As Figure 3 shown, the transmission screws 10 extend along the radial direction of the fixing sleeve 1. The transmission screws 10 respectively pass through the connecting seat 8, and the collar rings 9 are sleeved on the outer sides of the transmission screws 10. Internal threads that are screwed with the transmission screws 10 are provided on the inner walls of the sleeves 9.
