[0032] Furthermore, in this embodiment, by activating the drive component 5, the operation of the drive component 5 drives the second bevel gear 525 to rotate, the rotation of the second bevel gear 525 drives the first bevel gear 412 to rotate, the rotation of the first bevel gear 412 drives the threaded rod 413 to rotate, the rotation of the threaded rod 413 drives the second handle 414 to move, and the movement of the second handle 414 drives the fixed block 416 and the wrench head 417 to move, thereby achieving the effect of adjusting the length of the handle.
[0033] Example 2:
[0034] Based on Embodiment 1, a preferred embodiment of the manual torque wrench with adjustable handle length provided by this utility model is, for example... Figure 1-4 As shown: The limiting part 51 includes: a fixing plate 511, which is set in the movable groove opened in the handle 1. A connecting groove is opened on one side of the fixing plate 511, and a limiting groove is opened on the inner wall of the connecting groove; the bottom of the fixing plate 511 is fixedly connected to the bottom of the inner wall of the movable groove, and a fixing post 512 is fixedly connected to the inner wall of the connecting groove.
[0035] A rotating disk 513 is rotatably sleeved on the outer wall of the fixed column 512. A return spring 514 is fixedly connected to one side of the rotating disk 513. A connecting disk 515 is fixedly connected to one end of the return spring 514. The connecting disk 515 is adapted to the connecting groove.
[0036] The movable part 52 includes: a rotating rod 521, which is disposed on one side of the connecting plate 515; one side of the rotating rod 521 is fixedly connected to one side of the connecting plate 515; a limiting block 522 is fixedly connected to the outer wall of one end of the rotating rod 521; a connecting block 523 is fixedly connected to the other side of the rotating rod 521; a handle 524 is fixedly connected to one side of the connecting block 523; the other side of the rotating rod 521 passes through the inner wall of the movable groove and extends to the outside to be fixedly connected to the other side of the connecting block 523; and the limiting block 522 is adapted to the limiting groove.
[0037] The movable part 52 includes: a second bevel gear 525, which is sleeved on the outer wall of one end of the rotating rod 521. A second limiting groove is provided on the inner wall of the second bevel gear 525, and the second limiting groove is adapted to the first limiting groove. The second limiting groove is adapted to the limiting block 522. One side of the second bevel gear 525 is rotatably connected to the inner wall of the movable groove.
[0038] Furthermore, in this embodiment, by pulling the handle 524, the movement of the handle 524 drives the connecting block 523 to move, and the movement of the connecting block 523 drives the limiting block 522 and the rotating rod 521 to move. When the limiting block 522 moves away from the first limiting groove and moves completely into the second limiting groove, the handle 524 is rotated. The rotation of the handle 524 drives the rotating rod 521 to rotate through the connecting block 523. The rotation of the rotating rod 521 drives the bevel gear 525 to rotate through the limiting block 522, thereby achieving the effect of driving the extension component 4 to operate.
[0039] In use, pulling the handle 524 causes the connecting block 523 to move, which in turn moves the limiting block 522 and the rotating rod 521. Once the limiting block 522 has moved out of the first limiting groove and fully into the second limiting groove, rotating the handle 524 again causes the rotating rod 521 to rotate via the connecting block 523. The rotating rod 521 then drives the bevel gear 2 525 to rotate via the limiting block 522, which in turn drives the bevel gear 1 412 to rotate. The rotation of bevel gear 412 drives the threaded rod 413 to rotate, which in turn drives the handle 414 to move. The movement of handle 414 drives the fixed block 416 and the wrench head 417 to move, thereby adjusting the length of the handle. After the length of the handle is adjusted, the handle 524 is released. At this time, the return spring 514 drives the connecting plate 515 to reset. The movement of the connecting plate 515 drives the fixed plate 511 to move, which in turn drives the limit block 522 to move, causing the limit block 522 to return to the limit groove.
[0040] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
