Abstract
A bolster beam is correspondingly connected to a connection base by means of a damping unit; the radial dimensions of an outer wall of an inner supporting member and an inner wall of an outer supporting member gradually decrease from one end to the other end in a vertical direction; one of the inner supporting member and the outer supporting member is connected to the connection base, and the other one is connected to the bolster beam; when in use, the inner supporting member and the outer supporting member tend to be close to each other, and since surfaces, close to each other, of the two are configured to be tapered, the two can-not be relatively separated; when getting closer to each other, the inner supporting member and the outer supporting member produce a compression action on an intermediate buffer member, and the intermediate buffer member is elastically deformable.
