The damping cover is fixed in the damping shell and has a center hole defined, an inner wall of the center hole defines a plurality of loop-shaped groove perpendicular to the center hole and parallel each other. The damping body has a column portion received in the center hole, the column portion protrudes outward to form a plurality of rotating plates perpendicular to the column portion and parallel each other. The rotating plates engage the corresponding loop-shaped grooves. A bottom of the column portion connects a connecting portion located beneath the damping cover. The outer gasket is arranged around the connecting portion and against an inner side of the damping shell. Damping oil is filled between the outer gasket, the damping shell and the damping body.
