Description

Technical Field

[0001] The utility model relates to the technical field of hardware tools, in particular to a device for disassembling a shock absorber spring. Background Art

[0002] The shock absorber is mainly used to suppress the shock caused by the rebound of the spring after absorbing the shock and the impact from the road surface. When passing over uneven roads, although the shock-absorbing spring can filter the vibration of the road surface, the spring itself will still have reciprocating motion, and the shock absorber is used to suppress this spring jumping. If the shock absorber is too soft, the car body will jump up and down. If the shock absorber is too hard, it will bring too much resistance and hinder the normal operation of the spring. The operating conditions of the shock absorber are complicated. During long-term use, the shock absorber spring will often fail and need to be replaced with a new shock absorber spring. The existing technology uses wrenches, screwdrivers and other manual disassembly, which is time-consuming and labor-intensive. In order to solve the above problems, a device for disassembling the shock absorber spring is now proposed. Summary of the invention
