Abstract

The invention discloses a pair of pliers for a chain joint, which comprise a left plier body, a right plier body, a pivot and an elastic piece, wherein the left plier body is parallel to the right plier body or crossly abreast with the right plier body, and the left plier body and the right plier body are pivoted by using the pivot in the middle section; the elastic piece is arranged between the left plier body and the right plier body; the left plier body and the right plier body respectively comprise a plier part; each plier part is respectively bent and extended to be provided with a clamping block, and each clamping block is provided with a curve-shaped butting edge; and the clamping block of the left plier body corresponds to the clamping block of the right plier body. In the invention, the pair of pliers is butted against the chain end of a chain piece through the curve-shaped butting edges so as to form arc contact, thus the pair of pliers has the effect of stable operation.

Description

technical field [0001] The invention relates to a pliers for chain joints, in particular to a self-clamping connecting chain piece suitable for dismantling bicycle chains. Background technique [0002] The existing bicycle chains are connected to the chain pieces, mainly because there are more outer chain pieces and one more ring clamping groove at one or two ends of the chain tip. The outer chain piece is correspondingly provided with a C-shaped buckle edge, and then the outer chain piece Snap on the fastening groove, so as to prevent the chain tip from coming out. [0003] As for the disassembly of this type of connecting chain piece, it is necessary to use specialized tools to first fix the connecting chain piece, then stretch the outer chain piece, and finally use the push rod to extrude the chain tip to complete the disassembly. Therefore, the chain pullers currently classified in the patent international classification B21L 21 / 00 are suitable for this type of traditio...
