[0013] Beneficial effects of the utility model:

[0014] 1. The utility model provides an automobile bumper tow hook assembly, which is provided with a vacuum cavity tube and an air groove therein, and an appropriate amount of air is injected to adsorb a sliding piston. When the tow hook body is stretched, the air pressure in the air groove is reduced, adsorbing the tow hook body. When the tow hook body is hit, the compressed air causes the air pressure to rise, and then the tow hook body is pushed out, thereby solving the problem of metal fatigue that is prone to occur during the stretching process of the tow hook.

[0015] 2. The utility model provides a car bumper tow hook assembly. By setting a separation design, the bumper body can be freely separated from the bumper mounting plate, which facilitates the replacement of the bumper. At the same time, a damping spring is set to effectively reduce the impact force of the bumper during collision, thereby reducing damage to the vehicle. BRIEF DESCRIPTION OF THE DRAWINGS
