In FIGS. 4A-4F , various illustrations of the ratchet tooth assembly are shown, according to various embodiments. FIG. 4A shows ratchet tooth assembly 122 , ratchet pivot axis 126 , energy transfer opening 152 , and a ratchet pivot point 154 . FIG. 4B shows ratchet tooth assembly 122 , one or more spring-loaded teeth assemblies 124 , and one or more spring devices 156 . FIG. 4C shows a side view of ratchet tooth assembly 122 on the energy transfer opening side. FIG. 4D shows another side view of ratchet tooth assembly 122 . FIG. 4E shows a side view of ratchet tooth assembly 122 on the one or more spring-loaded teeth assemblies' side. In FIG. 4F , an illustration of the interaction between the ratchet tooth assembly and the drive gear assembly is shown. A fifth image 400 includes ratchet tooth assembly 122 , one or more loaded springs 402 , a tooth 124 , a tooth base 155 , primary gear 114 , a first primary gear tooth 160 , a second primary gear tooth 162 , and a third primary gear tooth 164 . In one example, tooth 125 is positioned on top of tooth base 155 . In this example, one or more loaded springs 402 makes contact with tooth base 155 . In this example, as tooth 125 and tooth base 155 move in a leftward movement pattern 404 , tooth 125 moves a primary gear tooth in a clockwise direction. In this example, a primary gear tooth moves in a clockwise direction which moves first primary gear tooth 160 up and to the right, second primary gear tooth 162 slightly up and to the right, and third primary gear tooth 164 down and to the right. Once tooth 125 moves primary gear tooth to the left, tooth 125 then moves in a rightward movement pattern 406 . During this rightward movement pattern 406 , tooth is reset onto a new primary gear tooth via tooth base 155 and one or more loaded springs 402 . This energy (e.g., movement) and/or a portion of this energy (e.g., movement) transferred from ratchet tooth assembly to drive gear assembly is transferred to one or more cams via one or more gears. In one example, 30 degrees of total movement back and forth is around the center hole. In various examples, any degrees (e.g., 0 degree, 1 degree, 2 degrees, 3 degrees, 10 degrees, 15 degrees, 20 degrees, 26 degrees, 29 degrees, 31 degrees, 43 degrees, etc.) may be utilized. In FIG. 5 , an illustration of the movement mechanism for the ratchet tooth assembly is shown, according to one embodiment. In one example, ratchet ball 128 is inserted into ratchet tooth assembly 122 via energy transfer opening 152 . In this example, one or more spring-loaded teeth assemblies 124 and/or one or more spring devices 156 are located (and/or coupled to and/or attached to and/or in proximity to) inside of ratchet tooth assembly 122 . In one example, as rotary force is applied to ratchet ball 128 (e.g., ball pin assembly, etc.), ratchet ball 128 spins on its axis. In one example, ratchet ball 128 is off center but concentrically. In another example, ratchet ball 128 is centered. Any mounting position may be utilized to transfer energy. In an example, ratchet ball 128 is mounted and spins in a larger circle inside ratchet tooth assembly 122 . Further, ratchet ball 128 may be mounted so that it fits inside the back of ratchet tooth assembly 122 in the elliptical relief cut out (e.g., energy transfer opening 152 ). This mating relationship causes ratchet ball 128 to collide only on the left and right of ratchet tooth assembly 122 but not on the top or bottom. This action causes ratchet tooth assembly 122 to pivot back and forth at a high rate of speed and impact. In one example, this back and forth movement of ratchet tooth assembly 122 transfers energy (e.g., movement, etc.) to tooth 125 which is positioned on top of tooth base 155 . Further, one or more loaded springs 402 makes contact with tooth base 155 . As tooth 125 and tooth base 155 move in a leftward movement pattern 404 , tooth 125 moves a primary gear tooth in a clockwise direction. In this example, a primary gear tooth moves in a clockwise direction which moves first primary gear tooth 160 up and to the right, second primary gear tooth 162 slightly up and to the right, and third primary gear tooth 164 down and to the right (see FIG. 4F ). Once tooth 125 moves primary gear tooth to the left, tooth 125 then moves in a rightward movement pattern 406 which may be matched (e.g., same direction—both parts move together, opposite direction—both parts move in opposite direction, etc.) with the movement of ratchet ball 128 . Further, it should be noted that the speed of both parts may be the same and/or different depending on the design. During this rightward movement pattern 406 , tooth is reset onto a new primary gear tooth via tooth base 155 and one or more loaded springs 402 . This energy (e.g., movement) and/or a portion of this energy (e.g., movement) transferred from ratchet tooth assembly to drive gear assembly may be transferred to one or more cams. In one example, 60 degrees of total movement back and forth is around the center hole. In various examples, any degrees (e.g., 45 degree, 46 degree, 47 degrees, 48.1 degrees, 49.7 degrees, 50.11 degrees, 53.001 degrees, 55 degrees, 59 degrees, 61 degrees, 83 degrees, etc.) may be utilized. In FIG. 6 , a diagram showing movement of the part is shown, according to one embodiment. A sixth image 600 includes first cam 106 B, second cam 106 A, and/or third cam 106 C. First cam 106 B, second cam 106 A, and/or third cam 106 C may interact with part 103 to move part 103 . In various embodiments, any number (e.g., 1-N) of cams may be utilized. In one example, first cam 106 B, second cam 106 A, and/or third cam 106 C may move in a clockwise direction to tighten and/or loosen part. Further, first cam 106 B, second cam 106 A, and/or third cam 106 C may move in a counter-clockwise direction to tighten and/or loosen part. In another example, first cam 106 B and second cam 106 A may move in a clockwise direction to tighten and/or loosen part. In another example, first cam 106 B and second cam 106 A may move in a counter-clockwise direction to tighten and/or loosen part. In another example, third cam 106 C and second cam 106 A may move in a clockwise direction to tighten and/or loosen part. In another example, third cam 106 C and second cam 106 A may move in a counter-clockwise direction to tighten and/or loosen part. In another example, first cam 106 B and third cam 106 C may move in a clockwise direction to tighten and/or loosen part. In another example, first cam 106 B and third cam 106 C may move in a counter-clockwise direction to tighten and/or loosen part. In one example, first cam 106 B, second cam 106 A, third cam 106 C, and Nth cam (not shown) may move in a clockwise direction to tighten and/or loosen part. Further, first cam 106 B, second cam 106 A, third cam 106 C, and Nth cam may move in a counter-clockwise direction to tighten and/or loosen part. In one example, one or more cams may not move while other cams are moving. In FIG. 7A , another illustration of the self-adjusting and open-ended wrench, according to one embodiment. In one example, open-ended and self-adjusting wrench 102 may include a drive gear assembly. Drive gear assembly may include primary drive gear 114 and one or more secondary drive gears 108 . Primary drive gear 114 may be secured to first element 116 (see FIG. 1 ). One or more secondary drive gears 108 may be secured to second element 104 A and/or third element 104 B. In one example, open-ended and self-adjusting wrench 102 may include a cam assembly. Cam assembly may include first cam 106 B, second cam 106 A, third cam 106 C, and/or Nth cam (not shown). Cam assembly may include any number (e.g., 1-N) of cams. In this example, cam assembly (e.g., first cam 106 B, second cam 106 A, and third cam 106 C) may be coupled to drive gear assembly (e.g., primary drive gear 114 and one or more secondary drive gears 108 ). In this example, drive gear assembly transfer energy (e.g., movement, the ability to move, etc.) to cam assembly. The movement (e.g., speed, direction, etc.) of the cam assembly is dependent on the movement (e.g., speed, direction, etc.) of the drive gear assembly. In one example, one or more of first cam 106 B, second cam 106 A, and/or third cam 106 C may interact with part 103 to move part 103 . In another example, first shield 120 A may be attached to second element 104 A to protect one or more elements attached to, on, and/or in proximity to second element 104 A. Further, second shield 120 B may be attached to third element 104 B to protect one or more elements attached to, on, and/or in proximity to third element 104 B. In one example, open-ended and self-adjusting wrench 102 may include universal adaptor 118 . In another example, open-ended and self-adjusting wrench 102 may be able to attach to, be coupled with, and/or interact with universal adaptor 118 . In one example, universal adaptor 118 may allow one or more power tools (and/or power tool types) to interact with, transfer energy to, and/or control open-ended and self-adjusting wrench 102 . In one example, universal adaptor 118 is a device that provides a path way and/or an interface device which allows one or more devices to interact with open-ended and self-adjusting wrench 102 . In one example, open-ended and self-adjusting wrench 102 may include ratchet tooth assembly 122 (see FIG. 7B ). In another example, open-ended and self-adjusting wrench 102 may be able to attach to, be coupled with, and/or interact with ratchet tooth assembly 122 .

In one example, ratchet tooth assembly 122 may allow one or more power tools (and/or power tool types) to interact with, transfer energy to, and/or control open-ended and self-adjusting wrench 102 . In one example, ratchet tooth assembly 122 is a device that provides a path way and/or an interface device which allows one or more devices to interact with open-ended and self-adjusting wrench 102 . In one example, power tool 136 may be any power tool (e.g., air, electric, mechanical, etc.). Further, power tool 136 may interact with, transfer energy to, and/or control open-ended and self-adjusting wrench 102 . In another example, ball pin assembly 130 may be utilized to transfer energy from power tool 136 to one or more of ratchet ball 128 , ratchet tooth assembly 122 , one or more spring-loaded teeth assemblies 124 , one or more drive gears, one or more cams, and/or any other device (see FIG. 1 , FIG. 2 , FIG. 4F , and FIG. 5 ). FIG. 8 shows various illustrations of the one or more cams, according to various embodiments. One or more cams 106 may include one or more connection points 107 . One or more connections points 107 may connect one or more cams 106 via a mechanical procedure, a chemical procedure, and/or any other connection process.

In another example, a rubber (e.g., plastic, and/or any other softer material) surface may be applied to outer surface of cam 800 . In this case, the rubber may allow the wrench to be utilized with more fragile materials (e.g., electronics, plastic, etc.). Any combination of materials (e.g., metals, plastics, rubber, etc.) may be utilized in the creation of the cams to provide varying strength, gripping power, precision, and/or touch (e.g., gentleness for specific material—electronics—plastics). In FIG. 9 , an illustration of one power tool being utilized with the self-adjusting and open-ended wrench is shown, according to one embodiment. A seventh image 900 includes a power tool 902 and self-adjusting and open-ended wrench 102 . In one example, power tool 902 may include a forward button 904 , a reverse button 906 , and an air inlet area 908 . In one example, when forward button 904 is selected one or more cams in self-adjusting and open-ended wrench 102 move in a first direction (e.g., clockwise). Further, when reverse button 906 is selected one or more cams in self-adjusting and open-ended wrench 102 move in a second direction (e.g., counter-clockwise). In FIG. 10A , another illustration of the self-adjusting and open-ended wrench is shown, according to one embodiment. In one example, ratchet ball 128 is inserted into ratchet tooth assembly 122 via energy transfer opening 152 (see FIG. 2 ). In this example, one or more spring-loaded teeth assemblies 124 and/or one or more spring devices 156 are located (and/or coupled to and/or attached to and/or in proximity to) inside of ratchet tooth assembly 122 . In one example, as rotary force is applied to ratchet ball 128 (via ball pin assembly, etc.), ratchet ball 128 spins on its axis (and/or spins off its axis center). In one example, ratchet ball 128 is off center but concentrically. In another example, ratchet ball 128 is centered. In an example, ratchet ball 128 is mounted and spins in a larger circle inside ratchet tooth assembly 122 . The movement of ratchet ball 128 may be seen by comparing the positions of ratchet ball 128 in FIG. 10A to FIG. 10B . Further, ratchet ball 128 may be mounted so that it fits inside the back of ratchet tooth assembly 122 in the elliptical relief cut out (e.g., energy transfer opening 152 ). This mating relationship causes ratchet ball 128 to collide only on the left and right of ratchet tooth assembly 122 but not on the top or bottom. This action causes ratchet tooth assembly 122 to pivot back and forth at a high rate of speed and impact. In FIG. 11 , another illustration of the self-adjusting and open-ended wrench is shown, according to one embodiment. In this example, self-adjusting and open-ended wrench 120 does not include (and/or is not attached to and/or is not coupled to) universal adaptor 118 and/or ratchet tooth assembly 122 . In this example, the energy transfer from power tool 902 occurs directly between self-adjusting and open-ended wrench 120 and power tool 902 . In this alternative image 1100 , the self-adjusting and open-ended wrench includes one or more cams 4 located on one or more surfaces 1 . Further, the self-adjusting and open-ended wrench includes one or more drive gears 5 . In this example, one or more cams 4 and/or one or more drive gears 5 may be attached by one or more attachment structures 6 to one or more surfaces 1 . In another example, a side shield 2 and/or a top shield 7 may be utilized. In another example, a primary drive gear 9 may be attached to a surface via another support structure 11 . Further, an assembly 12 may be utilized to power the drive gear assembly and/or the self-adjusting and open-ended wrench. In addition, a closure device 13 may be utilized.

The method may include placing one or more drive gears onto the third object (step 1212 ). The method may include connecting the first object to the third object and connecting the second object to the third object (step 1214 ). The method may include connecting the third object to a universal adaptor (step 1216 ). The method may include connecting the universal adaptor to the ratchet tooth assembly (step 1218 ). The method may include connecting the ratchet tooth assembly to the ball pin assembly (step 1220 ). The method may include connecting the ball pin assembly to the cam slide (step 1222 ). In one example, second cam 106 A is attached to one or more securing devices 110 . Further, one or more secondary drive gears 108 may also be attached to one or more securing devices 110 on second element 104 A and coupled to second cam 106 A. In addition third cam 106 C is attached to one or more securing devices 110 . Further, one or more secondary drive gears 108 may also be attached to one or more securing devices 110 on third element 104 B and coupled to third cam 106 C. Primary drive gear 114 may be attached to first element 116 . Further first cam 106 B may be attached to first element 116 and coupled to primary gear 114 . Optionally, first shield 120 A and second shield 120 B may be attached to second element 104 A and/or third element 104 B, respectively. Second element 104 A may be attached to first element 116 via support structure 112 . Further, third element 104 B may be attached to first element 116 via support structure 112 . First element 116 may be attached to universal adaptor 118 , ratchet tooth assembly 122 , and/or power tool 902 . In FIG. 13 , a flow diagram of one procedure for utilizing the self-adjusting and open-ended wrench 1300 is shown, according to one embodiment. The method may include attaching the power head to a power source (step 1302 ). The method may include orienting the wrench head perpendicular to the fastener and/or any other device (step 1304 ). The method may include selecting the appropriate direction for the power source (step 1306 ). The method may include placing the wrench in position to interact with the fastener and/or any other device (step 1308 ). The method may include utilizing the trigger to activate the wrench (step 1310 ). The method may include releasing the trigger when the fastener and/or any other device is in the desired location (step 1312 ). In one embodiment, a self-adjusting and open-ended wrench may include a drive gear assembly coupled to a power source. The drive gear assembly may include a primary drive gear located on a first element (e.g., reference number 116 from FIG. 1 , the structure below reference number 116 from FIG. 1 , and/or any portion thereof). The self-adjusting and open-ended wrench may include one or more secondary drive gears located on a second element (e.g., reference number 104 A from FIG. 1 and/or any portion thereof). The self-adjusting and open-ended wrench may include one or more secondary drive gears located on a third element (e.g., reference number 104 B from FIG. 1 and/or any portion thereof). Further, the first element may be coupled to the second element and the third element. The self-adjusting and open-ended wrench may include a cam assembly coupled to the drive gear assembly. The cam assembly may include a first cam (e.g., reference number 1068 on FIG. 1 ) located on the first element (e.g., reference number 116 from FIG. 1 , the structure below reference number 116 from FIG. 1 , and/or any portion thereof). Further, the cam assembly may include a second cam (e.g., reference number 106 A on FIG. 1 ) located on the second element (e.g., reference number 106 A from FIG. 1 and/or any portion thereof). The cam assembly may include a third cam (e.g., reference number 106 C on FIG. 1 ) located on the third element (e.g., reference number 104 B from FIG. 1 and/or any portion thereof). In addition, the first cam, the second cam, and the third cam may interact with each other to move a part (e.g., fastener, etc.). In one example, one or more cams are made of a softer material (e.g., rubber, plastic, etc.) to be able to handle sensitive parts (e.g., electronics, plastics, etc.). In another example, one or more cams are made of a harder material (e.g., steel, iron, etc.) to be able to handle tough parts (e.g., steel fasteners, etc.). In another example, one or more cams are made of softer material and one or more cams are made of harder material at the same time. A user may select which cams to utilize based on the part being worked on. For example, when a user is working on sensitive part the user may select an option that utilizes the one or more cams made of the softer material. Then, when the user moves onto a tougher part, the user may select an option that utilizes the one or more cams made of the harder material. In another example, the first cam may be coupled to the primary drive gear on the first element. Further, the second cam may be coupled to the one or more secondary drive gears located on the second element. In addition, the third cam may be coupled to the one or more secondary drive gears located on the third element. In another example, the first element may be coupled to the second element via a first support structure and/or the first element may be coupled to the third element via a second support structure. In another example, the second element may shield one or more secondary drive gears (and/or any other element attach to second element and/or any other element in proximity to second element) located on the second element and/or the third element may shield one or more secondary drive gears (and/or any other element attach to third element and/or any other element in proximity to third element) located on the third element. In another example, the self-adjusting and open-ended wrench may include a first top shield element coupled to the second element and/or a second top shield element coupled to the third element. In another example, the self-adjusting and open-ended wrench may include and/or be attached to a universal adaptor (and/or any adaptor—a first kind of adaptor may work with one or more power tools and a second kind of adaptor may work with different power tools, etc.). The self-adjusting and open-ended wrench may be coupled to the universal adaptor via the first element and/or any other element. In another example, the second element and the third element form a portion of a closure element. Further, the second element and the third element may be configured to move towards each other. In another example, the self-adjusting and open-ended wrench may further include and/or be attached to a ratchet tooth assembly. The ratchet tooth assembly may transfer energy from the power source to the drive gear assembly of the self-adjusting and open-ended wrench. Further, the ratchet tooth assembly may include one or more spring loaded teeth. The one or more spring loaded teeth may strike the primary drive gear of the self-adjusting and open-ended wrench to transfer energy to the drive gear assembly of the self-adjusting and open-ended wrench. In another embodiment, an apparatus may include a drive gear assembly which may be coupled to a power source. The drive gear assembly may include a plurality of drive gears. The apparatus may include a cam assembly which may be coupled to the drive gear assembly. The cam assembly may include a first cam and a second cam. The first cam and the second cam may interact with each other to move a part. In another example, the apparatus may further include a first leg and a second leg where the first leg and the second leg may form a V-shaped closure structure (and/or any other shaped closure—a C-shaped closure, a Y-shaped closure, a L-shaped closure, an X-shaped closure, a J-shaped closure, an O-shaped closure, a T-shaped closure, a U-shaped closure, and/or any combination thereof). In another example, the apparatus may further include a closing lever where the closing lever may move the first leg and the second leg towards each other. In addition, any number (e.g., 1 to N) of legs may be utilized. For example, a first leg, a second leg, and a third leg may be utilized. In addition, the legs may be on different planes. In one example, a first leg and a second leg are on the same plane and clamp down on the part to be worked on. Whereas, the third leg is on a different plane (e.g., above, below, etc.) which allows the third leg to interact with the first leg and the second leg to secure the part in place. In one example, the first leg and the second leg attach to the side of the part. Whereas, the third leg attaches to the top and/or both of the part. In another example, the closing lever may be attached to the first leg and/or the second leg. Further, the closing lever may be attached to any number (e.g., 1-N) of legs. For example, the closing lever may be attached to the first leg, the second leg, and the third leg. In another example, the closing lever may be attached to the first leg and the second leg but not the third leg. In addition, there may be more than one closing levers. For example, a first closing lever may be utilized to close the first leg and a second closing lever may be utilized to close the second leg. In addition, a first closing lever may be utilized to close the first leg and the second leg but a second closing lever may be utilized to close the third leg. Any number of legs and/or closing levers may be utilized in any combination. In another embodiment, a wrench may include a drive gear assembly coupled to a power source. The drive gear assembly may include a plurality of gears located on at least one of a first element, a second element, and/or a third element. The first element may be coupled to the second element and the third element. The wrench may include a cam assembly which may be coupled to the drive gear assembly. The cam assembly may include a first cam, a second cam, and/or a third cam located on at least one of the first element, the second element, and/or the third element. Any number (e.g., 1-N) of drive gears, cams, and/or any other element described in this disclosure may be utilized. Therefore, one, two, three, four, five, six, seven, eight, nine, ten, one million drive gears, cams, and/or any other element described in this disclosure are disclosed but for brevity purposes are not individually described in detail. Further, in one example, at least two of the first cam, the second cam, and the third cam are configured to interact with each other to move a part. In another example, N cams are disclosed where a fraction (e.g., 2 of 3, 2 of 4, 3 of 4, 2 of 5, 3 of 5, 4 of 5, 2 of 6, 3 of 6, 4 of 6, 5 of 6, 2 of 7, etc.) of the cams interact with each other to move a part. In another example, the wrench may further include and/or be attached to a universal adapter. In addition, the wrench may further include and/or be attached to a ratchet tooth assembly. In one example, the ratchet tooth assembly may be coupled to one or more power tools. In an example, the one or more power tools may include a power tool which has bidirectional movement where the bidirectional movement includes movements in a first direction and a second direction. In addition, the ratchet tooth assembly may cause movement in the drive gear assembly in a first movement direction based on the first direction of the power tool. Further, the ratchet tooth assembly may cause movement in the drive gear assembly in a second movement direction based on the second direction of the power tool. In one example, the self-adjusting and open-ended wrench may have one or more identification tags. For example, a radio frequency (“RF”) tag may be utilized to keep track of the location of the self-adjusting and open-ended wrench, the work performed by the self-adjusting and open-ended wrench, the utilization rate of the self-adjusting and open-ended wrench, any maintenance required, any maintenance history, and/or any other data relating to the self-adjusting and open-ended wrench. Further, the RF tag and/or a RF device may log one or more data elements and may transfer the one or more data elements to one or more devices. For example, a mobile device may receive information related to one or more self-adjusting and open-ended wrenches. In addition, the mobile device may issue commands, schedules, and/or any other signal based on the received information relating to the one or more self-adjusting and open-ended wrenches. As used herein, the term “mobile device” refers to a device that may from time to time have a position that changes. Such changes in position may comprise of changes to direction, distance, and/or orientation. In particular examples, a mobile device may comprise of a cellular telephone, wireless communication device, user equipment, laptop computer, other personal communication system (“PCS”) device, personal digital assistant (“PDA”), personal audio device (“PAD”), portable navigational device, or other portable communication device. A mobile device may also comprise of a processor or computing platform adapted to perform functions controlled by machine-readable instructions. In one example, a user may utilize this disclosure by attaching the wrench to a power head. Further, the power head may be attached to a power source. In this example, the user may orient the wrench head perpendicular to an appropriate sized fastener so that the cams are oriented around fastener. Further, the user may squeeze a trigger lever to activate the device (e.g., close one or more elements). In this example, the ratchet body may pivot and clamp down on one or more parts (e.g., fastener, etc.). In one example, the cams may spin in a unidirectional manor. Further, depending on the orientation (and/or the movement direction of the power tool) of the wrench to the fastener, the cams will either loosen or tighten the fastener. In this example, once the fastener is tightened or loosened to the operator's satisfaction or a device maximum, the release trigger lever may disengage and the cams may cease to rotate and the ratchet body pivots may release one or more parts (e.g., fastener, etc.). Further, the user may remove the device (e.g., wrench) from fastener and/or detach the wrench from the power source. In another example, this disclosure presents a unique powered ratcheting wrench capable of self-adjustment to allow the wrench to insert or extract (and/or tighten and/or loosen) hexagonal headed fasteners ranging in size from ¼ inches through ⅝ inches with respective head sizes of ⅜ inches through ⅞ inches. In addition, any shape (e.g. circle, elliptical, square, etc.) for the head of the fastener may be utilized with this disclosure. Further, any head size (e.g., less than ¼ inches and/or bigger than ⅝ inches) may be utilized with this disclosure. In addition, any size may be utilized (e.g., less than ¼ inches, less than ⅜ inches, greater than ⅝ inches, greater than ⅞ inches, etc.). This disclosure may be utilized in aviation, marine, automotive, any other industry, construction, repair, maintenance, and/or general hardware use. Further, this disclosure may be intended to allow access to hardware in difficult to reach places where the use of a standardized socket style wrench would not have access and where there is insufficient room to operate a box style wrench. In all embodiments, the wrench is designed as both a possible attachment to existing powered ratchet bodies and/or as a full customized complete tool (e.g., self-powered tool, etc.). It may be implemented as a pneumatic tool, power tool and/or battery operated. In another example, the wrench utilizes cams for tightening and loosing fasteners in hard to reach places. Further, this disclosure may ease the process in which tightening and loosing of fasteners occurs. Especially, in cases of insufficient space where current wrenches and ratchets fail. In another example, a power wrench may utilize gear-driven cams arranged in such a way around an open-ended pivoting wrench body as to allow the device to grasp any hexagonal fastener (and/or any other shaped fastener and/or any other shaped device) from ¼ inches to ⅝ inches and either tighten or loose it depending on the orientation of the wrench to the fastener and/or the directional movement of the power tool. As noted above, any size part may be tightened and/or loosened. Further, any shaped part may be tightened and/or loosened. In another example, a universal, open-ended, self-adjusting, cam driven wrench head, may include a cam slide set perpendicular to a wrench body for clamping force; a wrench body to house gears and cams; multiple small gears arranged on the wrench body for transferring rotational force to cams; and/or gear-driven cams for exerting rotational force on a fastener. In addition, the cams coupled with a gear shaft rotates while simultaneously forcing the cam slide toward the ratchet body engaging both internal clamping force onto an inserted fastener and exerting rotational force on contacting knurled cams through a number of small gears so as to facilitate loosening or tightening of the part (e.g., fastener, etc.) by contacting one, two, three, or more sides thus allowing the wrench to be applied to fastener perpendicular to the head as opposed to a socket-based device which must be placed over a fastener from a parallel approach. In another example, the open-ended self-adjusting, ratchet drive wrench may have a cam slide which is forced toward the ratchet body which in turn drives the ratchet body pivot and ratchet body pivot mirror and their components inward upon the fastener. In another example, with knurled cams shaped and arranged in the ratchet body pivot and ratchet body pivot mirror so as to contact the fastener at one or more points (e.g., one, two, three, etc.) simultaneously on a part (e.g., hexagonal fastener, etc.) of any size (e.g., in this case between ¼ inch and ¾ inch) with sufficient internal clamping force to facilitate tightening and losing of the fastener. In another example, the open-ended self-adjusting, ratchet drive wrench may have the knurled cams shaped and arranged in the ratchet body pivot and ratchet body pivot mirror so that when pressurized air is introduced into the air body drive the cam slide forward engaging the clamping force and/or simultaneously rotating the large bevel gear shaft and/or attached the large bevel gear which in turn rotates the bevel gear which through contacting a number of small gears turns the knurled cams in parallel thus rotating the inserted part (e.g., fastener, etc.) of any size (e.g., in this case between ¼ inch and ¾ inch) with sufficient torque to loosen and/or tighten the fastener. Additionally, in the case of long nuts, nuts positioned several inches down the bolt or specifically the tie rod end nuts on a car, where a socket will not facilitate removal and/or tightening of the part (e.g., fastener, etc.), an open-ended hand-held tool is required such as a box wrench and/or a crescent wrench, to tighten and/or remove such fasteners, which is significantly time consuming, burdensome and more often than not a painful endeavor trying to manipulate a wrench back and forth between various sharp, often hot metallic parts in an engine compartment. This disclosure shows an alternative head to the preexisting square socket-attachment head found on pneumatic ratchets. It is such that when assembled on and incorporated into the drive mechanism of a preexisting pneumatic ratchet (and/or other powered device), transforms the ratchet into an open-ended impact ratchet that auto-adjusts to fit fastener head sizes (e.g., in this case of ⅜ inch up to ⅞ inch) and facilitates tightening and/or removal of the part (e.g., fasteners, etc.). In one example, the wrench may be an adjustable pneumatic box wrench with an impact drive mode of operation to increase torque and efficiency. In one example, the wrench facilitates the removal and/or tightening of parts (e.g., fasteners, etc.) which are inaccessible to existing conventional pneumatic devices. In another example, through the use of rotary torque, rotational force is applied to the large bevel gear shaft while simultaneously forcing the cam slide towards the ratchet body through application of a slip gearing arrangement. Further, as torque is applied through the mechanism two distinct actions take place: 1) The wrench body may be actuated into significant clamping force on the bolt head through direct contact with the cams; and/or 2) Rotational force may conducted through the bevel gear shaft to the bevel gear. Rotational force may be transferred directly through the bevel gear to the small gears. In another example, the rotational force may be transferred directly through the small gears to the cams. In addition, the rotational force may be transferred directly through the cams to the head of the bolt (e.g., part). Further, cessation of torque may stop all transfer of force allowing for easy removal of the wrench from the bolt. In another example, the pivoting action allowed by the wrench body may allow the mechanism to firmly grasp the heads of bolts ranging in size from 0.25 inches to a maximum of 0.625 inches. In another example, the jaws of the wrench may expand for a positive gripping force to be applied to a part (e.g., bolt, etc.). In another example, the jaws of the wrench may be contracted to provide for positive gripping force on the part (e.g., bolt, etc.). Since this may be an attachment to a power head, there are several variations of power heads that will operate this device. These include pneumatic, electrical, battery operated and/or any new designs that may exist now and/or are developed at a later time that transfer energy. In various examples, there are several types of cams, materials and/or designs that will satisfy the requirements of this disclosure. The cams may include various knurled surfaces, textures, patterns to accommodate different size, shape and styles of parts (e.g., fasteners, etc.) and/or object not limited to fasteners. In another example, this disclosure may be utilized with an impact drive. In another example, this disclosure may not be utilized with an impact drive. The size of the device can change to accommodate larger and/or smaller parts. The materials used for every piece of the device are vast and will not be limited to any particular item. For instance, a plastic model may be made for low torque applications such as for use on models and/or electronic parts. The shapes of the parts may be redesigned to accommodate smaller and/or larger spaces. An identifying mark and/or placard may be included for tracking. The wrench and/or another device may include a reversing mechanism and switch. The wrench may include a locking mechanism. Further, a ratcheting or like mechanism may be included to tighten and lock the wrench onto a part. In one example, the wrench may be mounted onto a standard available air ratchet body with the factory supplied ratchet mechanism removed. This may be done by simply unscrewing the existing ratchet and replacing it with the adjustable air wrench attachment. In one example, the air body provides rotational force via the application of pressurized air supply. In one example, as high pressure air flows through the air body, two distinct actions take place: 1) Air pressure may drive the cam slide away from the wrench via the large circular end causing interaction with the ratchet body pivots are actuated into significant clamping force on the part head through direct contact with the cams; and/or 2) Rotational force may be conducted through the ball pin assembly. In one example, as rotary force is applied to the ball pin assembly, the assembly spins on its axis. The ball pin, which is off center but concentrically, mounted spins in a larger circle inside the ratchet tooth assembly. The ball pin may be mounted so that it fits inside the back of the ratchet tooth assembly in the elliptical relief cut out. This mating relationship causes the ball pin to collide only on the left and right of the ratchet tooth assembly but not on the top or bottom. This action causes the ratchet tooth assembly to pivot back and forth at a high rate of speed and impact. In one example, as the ratchet tooth assembly pivots, a built in single tooth (and/or multiple teeth) acts directly onto the drive gear indexing it one tooth at a time generating significant rotational and impactful force. This force may be directly transferred via gears to the cam gear assemblies giving direct rotational force to the knurled cams contained in the cam gear assembly. Further, rotational force may be transferred directly through the cams to the head of the part. In addition, cessation of torque may stop all transfer of force allowing for easy removal of the wrench from the part. In another example, the pivoting action allowed by the wrench body may allow the mechanism to firmly grasp the heads of part (e.g., in one case—bolts ranging in size from 0.25 inches to a maximum of 0.625 inches). Reference throughout this specification to “one example,” “an example,” “embodiment,” “further,” “in addition,” and/or “another example” should be considered to mean that the particular features, structures, or characteristics may be combined in one or more examples. The parts associated with this disclosure may be made and/or formed from steel, iron, plastic, rubber, glass, paper, any other similar material, and/or any other material. In addition, one or more parts may be made from similar material and/or a variety of materials. For example, a first part may be made of steel while a second part may be made of rubber. In one example, a cam may be a rotating or sliding piece in a mechanical linkage used especially in transforming rotary motion into linear motion or vice-versa. In another example, the cam may be a tooth, teeth, as is used to deliver power via a reciprocating (back and forth) motion in the follower, which is a lever making contact with the cam. In another example, a cylindrical cam or barrel cam may be a cam in which the follower rides on the surface of a cylinder. In one example, the follower rides in a groove cut into the surface of a cylinder. These cams may convert rotational motion to linear motion parallel to the rotational axis of the cylinder. A cylinder may have several grooves cut into the surface and drive several followers. Cylindrical cams may provide motions that involve more than a single rotation of the cylinder and generally provide positive positioning, removing the need for a spring or other provision to keep the follower in contact with the control surface. In another example a constant lead cam may be utilized (where the position of the follower is linear with rotation, as in a lead screw). It should be noted that any type of cam may be utilized with this disclosure. It should be noted that this disclosure has shown non-limiting examples of the wrench. The scope of the claims should not be limited by any examples utilized in this disclosure.
