Specifically, as shown in fig. 2 to 6, in the embodiment of the present application, the trailer hook is connected to the vehicle through the first shock absorbing portion 1, and is connected to the towed member through the rotating assembly 2, the rotating assembly 2 is slidably connected to the first shock absorbing portion 1, and the rotating portion 21 of the rotating assembly 2 is located in the first clamping groove 111, so that when the vehicle runs on a bumpy road, the towed member towed by the vehicle can be converted into the rotating portion 21 to stretch or compress the first elastic member 3 due to a larger reaction torque caused by uneven road surface.

Because the first elastic member 3 is located in the first clamping groove 111, and one end of the first elastic member 3 is connected with the rotating portion 21, and the other end is connected with the boss 12, the reaction torque can be consumed in the process of stretching or compressing the first elastic member 3 by the rotating portion 21, so that the reaction torque is reduced, the damping of the towing hook around the axial rotation direction of the towing hook is realized, the drivability and riding comfort of a vehicle are improved, and the problems that the vehicle is damaged by the larger reaction torque and the vehicle turns are avoided.

One end of the first elastic member 3 may be connected to the rotating portion 21 by welding, bonding, or the like, and the other end may be connected to the boss 12 by welding, bonding, or the like, and may be selected by those skilled in the art according to actual needs, which is not particularly limited herein.
