Problems solved by technology

[0002] As an important part of various vehicles, the oil shock absorber's damping characteristics directly affect the safety, stability and comfort of the vehicle operation. The oil shock absorber bottom valve is an important component structure to ensure the damping characteristics of the oil pressure shock absorber , the existing installation method of the bottom valve of the oil pressure shock absorber is mostly bolt and nut connection. This connection method is easy to rust and fix into a dead knot. During maintenance, maintenance workers are not easy to disassemble and replace, which wastes manpower and financial resources, and the work efficiency cannot be guaranteed.
