Technical Field

The utility model belongs to the technical field of machinery, especially, relate to a multipurpose circlip handling instrument.

Background

In the case of mechanical maintenance, when the circlip (for shaft or hole) needs to be attached or detached, it is usually done by using special pliers. Because the spring collar is a common part positioned along the axial direction when the fittings are arranged on the shaft, in order to ensure that the spring collar can be tightly clamped on the shaft without sliding or falling off, the spring collar generally has stronger internal contraction force, and therefore, special pliers are required to be used for outward expansion before assembly and disassembly. The clamp body of the special clamp in the prior art is generally integrally formed, all parts of the clamp body are on the same plane, when a spring clamping ring needs to be assembled and disassembled on a shaft, the clamp body is kept parallel to the shaft, a jaw is inserted into a small hole on the spring clamping ring, and the clamp body is pressed to expand the spring clamping ring to complete assembling and disassembling. But to the spring collar of the less model of loading and unloading, it is comparatively convenient to obtain special pincers, and the while operation is also simple relatively, and to the spring collar of great model, the difficulty is great, shows as: firstly, it is difficult to obtain a special tool; secondly, the spring retainer ring with a larger size has higher rigidity, so that the spring retainer ring is not easy to elastically deform, and therefore, the operation is difficult and has higher danger. Therefore, the multipurpose spring retainer ring assembling and disassembling tool which is wide in application range, simple and convenient to operate and high in safety is a technical problem which needs to be solved urgently by technical personnel in the field.
