[0002] Currently, shock absorbers are used in a wide range of fields, and different fields have different technical requirements for shock absorbers. The main function of spring shock absorbers is to suppress the shock caused by the rebound of the spring after absorbing shock, as well as the impact from the road. In order to reduce the impact of the vibration on the unit, the spring needs to release the energy of the absorbed vibration impact and consume the energy that affects the stability of the unit. At the same time, it must ensure that the normal operation of the spring and the unit is not affected. This is when the importance of the shock absorber's appearance design is reflected. Therefore, the appearance design of the shock absorber should try to understand the environment in which it will be used, the weight of the equipment, and the material selected for the shock absorber. The shock absorber should be selected according to local conditions to solve the corresponding problems.
