The multiple groups of special-shaped blocks 12 are arranged in an inclined shape. The surface of the special-shaped blocks 12 is provided with an inclined surface, and the inclined surface is close to the inner wall of the movable ring 8. The special-shaped blocks 12 are slidably inserted into the inner wall of the movable ring 8, so that the special-shaped blocks 12 can be gathered inside or spread around according to the needs of use, which is convenient for disassembly and maintenance.
