Preferably, the embodiment of the present invention adopts a spring structure as a vibration damping body for reducing vibration transmission upwards, specifically, the vibration damping body includes a spring connecting shaft 5 and a compression spring 6, and the compression spring 6 is sleeved outside the spring connecting shaft 5. Wherein, the minimum circumcircle of the opening structure on the upper portion of the damping box body 3 is larger than the shaft diameter of the spring connecting shaft 5 and smaller than the middle diameter of the compression spring 6, so that the spring connecting shaft 5 can penetrate out of the upper portion of the damping box body 3, and the compression spring 6 is limited in the hollow inside of the damping box body 3, and can be of a polygonal opening structure, also can be of an open pore structure, and is preferably a through hole.
