Abstract
A shock-absorbing device includes an outer threaded tube, a threaded rod having a retractable rod, a compression spring, an adjusting nut, and an urging nut. Thus, when the urging nut on the outer threaded tube is unscrewed, the threaded rod can be rotated relative to the outer threaded tube, thereby adjusting the relative distance between the threaded rod and the outer threaded tube, such that the height of the automobile can be adjusted largely. In addition, the scales of the flat surface can be used to indicate the length of the shock-absorbing device, so that the height of the automobile can be adjusted exactly.
