The circular ring 5 is fixedly connected with the outer side of the connecting seat 4 through the connecting plate, and the rotating ring 9 is sleeved on the outer side of the circular ring 5. In order to ensure that the gears 14 on the outer side of each fixing bolt 13 are meshed with the gear ring 11, the fixing bolts 13 are evenly distributed in a circumferential array, and the gears 14 are meshed and connected with the gear ring 11. The inner diameter size of the limiting groove 8 is adapted to the outer diameter size of the limiting ring 10, and the limiting ring 10 is slidably connected with the inside of the limiting groove 8.
