[0023] A first bearing 23 is installed in the first mounting hole 21. The first bearing 23 is matched with a first screw rod 24. The first screw rod 24 is threadedly connected in the first threaded hole 13. The arc surface clamping plate 2 is located at the lower side of the arc segment and fits with the lower end surface of the arc segment.
[0024] The lateral clamping plate 3 is located inside the matching ring 1, and a second mounting hole 31 is opened on the lateral clamping plate 3. Second matching rods 32 are symmetrically fixedly arranged on the lateral clamping plate 3 at both ends of the second mounting holes 31.
