The tops of the four connecting blocks 12 are commonly connected to a rotating ring 13, and a U-shaped block 15 is fixedly connected to each of the four connecting blocks 12. A driving gear 14 is installed at the top of the sleeve 8, and the driving gear 14 movably fits the inner wall of the rotating ring 13.
