[0001] The utility model relates to the technical field of shock absorbers, in particular to a high-strength and deformation-resistant shock absorber. Background Art

[0002] The main function of the shock absorber is to suppress the vibration when the spring rebounds after absorbing shock, and to absorb the energy of road impact.
