The inner body comprises a base and a limiting tube connected to the base, the limiting tube is arranged in a hollow manner, and a side surface of the limiting tube is provided with a plurality of limiting grooves extending in an axial direction. The tube base is provided with one or more bulges, an outside surface of each bulge is provided with outer threads. The tube base is arranged in the limiting tube of the inner body. The bulge on the tube base transversely passes through the limiting grooves. The outer threads on the bulge are in threaded connection to inner threads on the sleeve.
