Snap spring pliers for efficiently assembling piston check ring

Abstract

The invention provides a pair of snap spring pliers for efficiently assembling a piston check ring, and belongs to the technical field of piston check ring assembling. The clamp spring pliers for efficiently assembling the piston check ring comprise a handle part, a hinging part and a clamping part. The included angle between the first handle and the second handle is driven to change under the action of a human hand, so that the clamping cylindrical table can be inserted into a mounting hole in the piston check ring, the angles of the first handle and the second handle are driven by the human hand to change reversely, the piston check ring is opened through the clamping cylindrical table for assembly, and the first handle and the second handle are subjected to arc treatment and accord with human engineering; under the normal opening degree of a palm, the opening degree of the sharp-nose clamping cylindrical table can reach the size of a check ring hole, the clamping cylindrical table on the sharp-nose arc-shaped rod is in a boss type, the clamping cylindrical table is in a cylindrical type, stress generated in the axial direction of the clamping cylindrical table when the piston check ring is opened is reduced, falling of the piston check ring is reduced, and the service life of the piston check ring is prolonged. And the piston retainer ring can smoothly enter the groove when being assembled to the piston.

Description

technical field [0001] The invention relates to the field of assembling piston retaining rings, in particular to a snap ring pliers for efficiently assembling piston retaining rings. Background technique [0002] The piston retaining ring is an elastic retaining ring used when the piston is assembled. When the piston retaining ring is assembled, a caliper is used to clamp and stretch the piston retaining ring. The opening and closing angle is relatively large, and it is laborious to use for a long time by hand, and the end of the clamping part of the circlip pliers is set in a small circular truncated shape. Although it is easy to insert into the mounting hole on the piston retaining ring, it is easy to fall off after the piston retaining ring is stretched. Contents of the invention [0003] In order to make up for the above deficiencies, the present invention provides a snap ring pliers for efficiently assembling the piston retaining ring, which aims to improve the openin...
