[0031] Specifically, this utility model uses a pull plate 19 to pull the fixing post 18, which moves within the movable hole 16. The spring 20 then stretches accordingly. Once one end of the fixing post 18 disengages from the fixing hole 17, the second extension bar 13 can be moved to the position of the connecting channel 12 of the first extension bar 11. After the adjustment hole 14 aligns with the position of the fixing post 18, the pull plate 19 is released. Under the action of the spring 20, the fixing post 18 moves within the movable hole 16. Once one end of the fixing post 18 is engaged in the adjustment hole 14, the first extension bar 11 and the second extension bar 13 are fixed, thus achieving the purpose of adjusting the length of the first extension bar 11 and the second extension bar 13.

By reasonably extending the arm length of the pliers body 1, the applicability of the pliers body 1 can be improved.
[0032] Working principle:
[0033] The operator can adjust the arm length of the pliers body 1 according to actual needs. During adjustment, the operator pulls the fixing post 18 through the pull plate 19. At this time, the fixing post 18 will move within the movable hole 16, and the spring 20 will perform a corresponding stretching movement. After one end of the fixing post 18 disengages from the fixing hole 17, the second extension bar 13 can be moved to the position of the connecting channel 12 of the first extension bar 11. After the adjustment hole 14 aligns with the position of the fixing post 18, the pull plate 19 is released. At this time, under the action of the spring 20, the fixing post 18 will be driven to move within the movable hole 16. When one end of the fixing post 18 is engaged in the adjustment hole 14, the first extension bar 11 and the second extension bar 13 can be fixed, thereby achieving the purpose of adjusting the length of the first extension bar 11 and the second extension bar 13, and indirectly achieving the purpose of adjusting the arm length of the pliers body 1. Then, the operator uses the pliers body 1 to process the workpiece. When using the pliers body 1, a connecting shell 2 is fixed to the pliers arm of the pliers body 1. A first connecting ear 3 and a second connecting ear 5 are fixed to the outer wall of the connecting shell 2. A threaded rod 7 is connected to the first connecting groove 4 and the second connecting groove 6 of the first connecting ear 3 and the second connecting ear 5. A silicone column 8 is installed on the outer wall of the threaded rod 7. With the cooperation of the threaded rod 7 and the silicone column 8, the user's hand can be prevented from directly contacting the pliers arm of the pliers body 1 when the user is bending the pliers arm, thus avoiding discomfort or even abrasion to the user's hand. This meets the current needs. The operator can use an external tool to rotate the fixing ring 10 and disengage the fixing ring 10 from the outer wall of the threaded rod 7, thereby removing the threaded rod 7 from the first connecting groove 4 and the second connecting groove 6, achieving the purpose of disassembling the silicone column 8. Therefore, this utility model facilitates the disassembly and maintenance of the silicone column 8, and helps to improve the working efficiency and cleanliness of the silicone column 8.
