The outer tube is composed of six outer tube ribs arranged in a regular hexagon. The middle of the outer tube ribs is connected to the inner tube. Both ends of the outer tube ribs are connected to support ribs. The support ribs are radially arranged and connected to the inner tube on the inside. One end of the inner ring is fixed to the end piece, and the other end is inserted into the inner tube.
