Abstract
A universal joint includes a seat body, a cover body, a damping member, and an elastic member. The cover body is fixed on the seat body and the cover body and the seat body form a cavity together. The damping member and the elastic member are respectively located on opposite sides of the cavity. The elastic member is fixed on the seat body and maintained below the cover body. The damping member is fixed on the cover body and maintained above the seat body. The universal joint of the present disclosure has the beneficial effect of structural stability, avoiding the problem of insufficient clamping force or even failure.
