In general, the auto repair tools used in a narrow space cannot adjust the size of the jaws. Therefore, the user has to repeatedly insert a tool of various sizes into a narrow space to compare with the workpiece to be pulled. The size of the tool is extremely inconvenient, and tools of various sizes must be prepared, which are costly and difficult to carry.

It is customary to adjust the size of the wrench or the wrenching tool, and the size of the jaw is adjusted by the distance between the fixed jaw and the movable jaw, and the adjusting mechanism is mostly located at the head of the wrench, that is, near the jaw. However, as a tool for auto repair tools, it is often necessary to extend into a narrow space for work. The jaw adjustment mechanism of such an adjustable wrench will enter a narrow space and is difficult for the user to adjust according to the size of the workpiece to be pulled. If the visual adjustment is made multiple times in and out, it will reduce the work efficiency and it is quite inconvenient.

On the other hand, since the size of the jaw is controlled only by the movement of the movable jaw, the range of the size of the jaw is limited, and the user still needs to prepare a variety of tools for use.

The main purpose of this creation is to provide a wrench that can quickly adjust the jaws. Small, simple and easy to use.

In order to achieve the above object, the present invention provides a wrench comprising a body, two clamping members, a set of components and two connecting arms.

Each of the clip members 20 further defines a through hole 22 passing through the through slot 21, and each of the clip members 20 is formed toward one side of the other clip member 20. A jaw portion 23, the distance between the two jaw portions 23 is defined as a jaw width. In the main embodiment of the present invention, the clamping portion 23 is a flat surface and is parallel to the axial direction. Therefore, the two clamping portions 23 are also parallel to each other.

The sliding member 30 is sleeved on the screw segment 13 of the body and can slide along the length of the screw segment 13. One end of each connecting arm 40 is pivoted to the sliding member 30, and the other end is worn by a pivoting member 41. The through hole 22 of one of the clips 20 is pivotally disposed on the clip member 20, and the pivoting member 41 is slidable in the sliding slot 121. One end of the rotating member 50 is rotatably away from the sliding member 30. One end of the Y-shaped portion 12 is connected, and the screw member 50 has an internal thread and is screwed to the screw segment of the body Preferably, the screw member 50 covers a portion of the grip portion 11, that is, the lower portion of the screw segment 50 is completely covered, and the outer wall of the screw member 50 is formed with a three-dimensional embossing pattern for the hand-held rotation.

In the main embodiment of the present invention, the sliding member 30 includes two pressing members 31, and the two pressing members 31 sandwich the screw portion 13 of the body therebetween, in other words, between the two pressing members 31. The clamping portion is disposed in the clamping space, and the connecting arm 40 is sandwiched between the two pressing members 31 and the two connecting arms 40 are respectively located on opposite sides of the screw segment 13 The pivoting member 32 passes through the two pressing members 31 and one of the connecting arms 40 to pivot the connecting arm 40 relative to the two pressing members 31 with the pivoting member 32 as an axis, and each of the connecting arms 40 is bent Folded and bent toward the Y-shaped portion 12, one end of each connecting arm 40 connecting the clip member 20 has a U-shaped groove 42, and the clip member 20 is disposed in the U-shaped groove 42. 41 passes through the side walls of the U-shaped groove 42 and the through holes 22 of the clip member 20 to pivotally connect the connecting arm 40 to the clip member 20.

In addition, an annular groove 311 is defined in the axial direction of the pressing member 31. The locking member 50 has a latching portion 51 near the end of the sliding member 40. The portion 51 includes a large diameter portion 511 and a small diameter portion 512. The large diameter portion 511 is closer to the sliding member 30. The outer diameter of the large diameter portion 511 is larger than the outer diameter of the small diameter portion 512 but smaller than the spiral rotation. In addition to the outer diameter of the portion of the member 50 except the latching portion 51, the large diameter portion 511 is received in the second ring groove 311 to rotatably provide the screw member 50 to the sliding member 30. The moving member 30 is dropped, and the screw member 50 and the sliding member 30 are interlocked in the axial direction.

In addition, the sliding member 30 further includes a positioning member 33 passing through one of the pressing members 31 and selectively extending into the thread of the screw segment 13 so that the sliding member 30 cannot be along the screw The segment 13 moves up and down, whereby when the size of the jaw is adjusted and it is desired to be pulled, The positioning member 33 can be locked to avoid the rotation of the screw member 50 caused by the pulling process to loosen the overall structure. Moreover, the sliding member may further comprise at least one fixing screw disposed in the screw hole of the two pressing members to press the two pressing members to each other, thereby adjusting the pivoting of the two connecting arms relative to the sliding member The ease of use.

In practical use, referring to FIG. 3 and FIG. 4, the clamping gap formed between the two clamping members 20 can hold a workpiece, and the grip portion 11 is pulled to drive the workpiece to rotate, and if the clamping width is In contrast to the size of the workpiece to be clamped, the user can move the sliding member 30 upward or downward by rotating the screw member 50, and the sliding member 30 drives the two connecting arms 40 upward or upward. Moving downwardly, the two connecting arms 40 further drive the two clamping members 20 to slide along the two arm portions 121 to bring the two clamping members 20 closer to or away from each other. More specifically, when the user has to widen the width of the jaw, the screw member 50 is rotated to move the screw member 50 along the screw segment 13, and the sliding member 30 and the two connecting arms are coupled. 40 moves up, and since the two arm portions 121 extend obliquely upward, the upwardly moving connecting arm 40 drives the clip member 20 to move along the arm portion toward the free end of the arm portion 121, that is, the second The clips 20 are spaced apart from each other to increase the width of the jaws; conversely, when the user has to reduce the width of the jaws, the screw member 50 is reversely rotated to move the screw member 50 downward along the screw segments 13. The sliding member 30 and the two connecting arms 40 are moved downward, and since the two arm portions 121 extend obliquely upward, the downwardly moving connecting arm 40 drives the clamping member 20 along the arm portion 121 toward the arm portion 121. The body moves, that is, the two clips 20 are close to each other to make the width of the jaws small. The slidable member 12 is slidable in the sliding slot 1211, so that the clip member 20 cannot slide infinitely on the arm portion 121 to avoid the clip member 20 and the arm. The portions 121 are separated from each other.

In addition, since the two clamp members 20 are linearly moved, the two jaw portions 23 can be maintained parallel to each other, and the parallel and average clamping can be maintained regardless of the width of the jaws. And The two clamping members 20 are moved by the two arm portions 121, and the actuation is relatively stable, and the two clamping members 20 are sleeved on the arm portion 121. Therefore, when the workpiece is pulled, the torque of the clamping portion 23 is not It is transmitted to the connecting arm 40, the sliding member 30 and the screw member 50, reducing the probability of component damage.

In summary, the wrench structure provided by the present invention is simple and easy to manufacture and assemble, and the operation is simple and does not require complicated and fine structure. The most important thing is that the user can quickly adjust the width of the jaw to facilitate the clamping with a simple operation. The size of the workpiece, and all the components are on the same plane, and the moving paths of all the components are also on the same plane, so that the creation can be operated in a narrow space, compared with a wrench with a fixed jaw and a movable jaw. The width of the mouth can be adjusted to a larger extent, which is effective.
