[0002] Shock absorbers are used to suppress the shock caused by the rebound of springs after absorbing shock and the impact from the road surface. They are widely used in automobiles to accelerate the attenuation of frame and body vibrations to improve the driving smoothness of the car. When passing through uneven roads, although the shock-absorbing spring can filter the vibration of the road, the spring itself will still have reciprocating motion, and the shock absorber is used to suppress this spring jumping.

For example, a shock absorber compression valve assembly disclosed in Chinese patent announcement No. CN202510614U, however, since the pressure of the spring on the valve body cannot be adjusted according to different usage requirements, the application scope of the compression valve assembly is relatively single.

[0027] A second connecting column 10 is fixedly connected to the surface of the ring 84, and a second cylinder 11 is fixedly connected to the side of the second connecting column 10 away from the ring 84. The inner wall of the second cylinder 11 contacts the surface of the spring seat 2. A second strip hole 12 is opened on the surface of the spring seat 2.

At the same time, when the sleeve is separated from the bolt 81, the elastic force of the U-shaped spring sheet 15 makes the left and right sides of the bolt 81 contact with the side of the limit block 16. At this time, the bolt 81 can be locked by the limit block 16, and the bolt 81 cannot rotate after being vibrated.
