Special tong for assembling and disassembling chains

Abstract

A special tong for assembling and disassembling chains comprises a first half body and a second half body, wherein the first half body and the second half body are pivotally connected to each other; a first transverse recess is formed in a first clamping portion of the first half body, is positioned in the inner side surface of the first clamping portion and runs through a left side surface and a right side surface of the first clamping portion; the width of the inner side surface of the second clamping portion of the second half body is greater than that of the inner side surface of the first clamping portion; a second transverse recess and two intervening preventing recesses are formed in the second clamping portion; the second transverse recess is positioned in the inner side surface of the second clamping portion and runs through a left side surface and a right side surface of the second clamping portion; and the intervening preventing recesses are respectively formed in the left side surface and the right side surface of the second clamping portion. Owing to the intervening preventing recesses, when a positioning plate is assembled or disassembled, the tong can be prevented from colliding with an adjacent latch, intervening is avoided, and assembling and disassembling operations are quite quick and convenient.

Description

technical field [0001] The invention relates to a hand tool for disassembling parts of a bicycle, in particular to a special pliers for chain disassembly and assembly. Background technique [0002] Bicycle chain 40 of present prior art, as Figure 8 to Figure 10 As shown, an outer plate 41 and an inner plate 42 are provided. The outer plate 41 has a pair of outer plates 411 , and each outer plate 411 has a through hole 412 . The inner plate 42 has a pair of inner plates 421 , and each inner plate 421 has a through hole 422 . [0003] A pair of bushings 43 are arranged between the inner plate 42 and the outer plate 41, and each bushing 43 is rotatably covered and sleeved by a rotor 44, and a corresponding bushing is provided through the corresponding through holes 412 and 422. 43 is sleeved with a latch 45 , and one end of the latch 45 protruding outward is provided with an annular embedding groove 451 . [0004] There is also a slightly C-shaped positioning piece 46 , and ...

AI Technical Summary

Problems solved by technology

[0010] The purpose of the present invention is to solve the problem that the outer side of the clamping part of the clamp is easy to collide with the adjacent pins and cause interference. The left and right sides are provided with anti-interference recesses, so the present invention can prevent the pliers from colliding with the adjacent pins and avoid interference when disassembling and assembling the positioning piece, and makes the disassembly and assembly operation very fast and convenient
