Detailed Implementation

[0023] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. However, it should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit its scope. Furthermore, in the following description, descriptions of well-known structures and technologies are omitted to avoid unnecessarily obscuring the concepts of this utility model.

[0024] See Figure 1 This application provides a pair of pliers with a protective function, including two plier bodies 1, which are rotatably connected to each other via a plier shaft assembly 2. Each plier body 1 is provided with a protective mechanism 3. Each plier body 1 includes a jaw 11 and a plier handle 12 connected to the jaw 11. The protective mechanism 3 includes a jaw protection component 31 and a plier handle protection component 32. The jaw protection component 31 is disposed on both sides of the jaw 11, and the plier handle protection component 32 is connected to the plier handle 12.

[0025] See Figures 2-4 Specifically, the clamp shaft assembly 2 includes a bushing 21 and a stepped central shaft 22. The bushing 21 is connected to the jaw 11 through a shaft hole. The middle part of the stepped central shaft 22 is connected to the bushing 21. The stepped central shaft 22 has stroke grooves 23 at both ends, and multiple positioning holes 231 are provided in the stroke grooves 23.

[0026] Specifically, threaded sections 221 are provided at both ends of the stepped central shaft 22. The threaded sections 221 are connected to limit caps 24 through threaded engagement. The limit caps 24 are used to limit the movement of the jaw protection component 31 and prevent it from falling off during movement. The threaded connection also facilitates the replacement of the jaw protection component 31 if it is damaged.

[0027] Specifically, the jaw protection assembly 31 includes a locking ring 311 and a protective connecting ring 312. The locking ring 311 and the protective connecting ring 312 are sequentially connected to the side end of the stepped central shaft 22. The locking ring 311 has a locking groove 313 on the side near the protective connecting ring 312. The bottom end of the protective connecting ring 312 has a locking block 314 on the side near the locking ring 311. The locking block 314 and the locking groove 313 are connected by a mating connection. The locking block 314 and the locking groove 313 cooperate to restrict the degree of freedom of the locking ring 311 and prevent the locking ring 311 from rotating during movement.

[0028] Specifically, the inner ring wall of the locking ring 311 is provided with a travel block 315, which is connected to the travel groove 23. The locking ring 311 is provided with a second positioning hole 316, and the first positioning hole 231 and the second positioning hole 316 are connected by a positioning pin 317. By inserting and removing the positioning pin 317, the locking ring 311 and the stepped central shaft 22 can be quickly installed and removed.

[0029] Specifically, the protective connecting ring 312 is provided with a connecting rod 318, and the top end of the connecting rod 318 is connected to a clamping protective member 319. The clamping protective member 319 clamps the item, which stabilizes the small item and prevents it from splashing.

[0030] See Figure 5 Specifically, the pliers handle protection assembly 32 includes an anti-slip sleeve 321, which is disposed on the pliers handle 12, and a hand guard 322 is connected to the top of the anti-slip sleeve 321.

[0031] The working principle of this utility model:

[0032] When using this pair of pliers to cut or crush small items, place the item between the jaws 11. Adjust the clamping distance between the clamping protective members 319 according to the size of the item. First, pull out the positioning pin 317 and move the locking ring 311. At this time, the locking block 314 and the locking groove 313 are tightly connected. Therefore, the protective connecting ring 312 and the locking ring 311 move synchronously until the clamping protective members 319 clamp the item. Then, insert the positioning pin 317 into the positioning hole 231 corresponding to the current position to fix the clamping protective member 319. This forms a protective barrier, facilitating subsequent cutting.

[0033] When processing large items, in order to avoid obstructing the working opening of the jaws 11, pull the protective connecting ring 312 forcefully to pull the locking block 314 out of the locking groove 313, rotate the protective connecting ring 312 to drive the clamping protective member 319 to rotate around the stepped central axis 22 until the clamping protective member 319 completely avoids the working opening of the jaws 11, and then push the protective connecting ring 312 to insert the locking block 314 into the locking groove 313, thus completing the fixation of the clamping protective member 319 in this state.

[0034] The above description is only a preferred embodiment of this utility model and is not intended to limit this utility model. Any modifications, equivalent substitutions or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
