Specifically, each set of the friction plates has a same thickness in a radial direction of the sleeve and has a different friction coefficient of a surface of one side which is in contact with the outer wall of the piston rod, and the friction coefficient decreases from the closed end to the open end of the sleeve. Alternately, each set of friction plates are of a same material, and a thickness of the friction plates in a radial direction of the sleeve is different, and the thickness of each set of friction plates decreases from the closed end to the open end of the sleeve. The shock absorber of the present disclosure is simple and practical, and the cost is low, and the structure can ensure that the damping force is variable under different load and the rotational speed conditions.
