By adopting the technical scheme, when the spring body is compressed and deformed, the upper cylinder body can move relative to the lower cylinder body under the guidance of the guide post and the guide groove.

Further, the guide post slides in the guide groove.

Through adopting above-mentioned technical scheme, make wave spring elasticity more even, improve the holding power of spring.

(III) advantageous effects

Compared with the prior art, the utility model, following beneficial effect has:

1. in order to solve the problems that the gap formed by wave crests and wave troughs in the existing wave spring is large, and the spring can be seriously damaged when the spring is subjected to large instantaneous impact force, so that the spring loses elasticity and the using effect is influenced, the utility model discloses a spring body, a wave-shaped groove and a rubber plug are arranged, and the rubber plug is nested and installed in the wave-shaped groove, so that the elastic force of the spring body can be increased, the instantaneous bearing force of the spring is improved, and the using effect of the wave spring is improved;

2. for having a plurality of grooves on solving current wave spring, taking place the distortion easily when using, in making support piece embedded groove, influence the problem of the use of spring, the utility model discloses a set up upper end cover, last barrel, bottom end cover and lower barrel, can increase wave spring's holding power, make the spring more even in the elasticity of use, can effectively prevent the wave spring atress to take place the distortion simultaneously, ensure spring normal use.
