By rotating the inner rod 242, the length of the telescopic support leg 24 can be adjusted to adapt to different heights of the centering disk 1. At the same time, the end of the inner rod 242 away from the centering disk 1 is designed as a rounded structure.

[0041] Furthermore, a plurality of threaded holes 211 are provided at equal intervals around the circumferential direction on one side of the adjustment disk 21 away from the connecting column 213, and the number of the threaded holes 211 is at least three or more, and an outer sleeve 241 is provided with external threads at one end, and the outer sleeve 241 is threadedly connected and fixed with the threaded holes 211 through the external threads. In actual use, the position of the telescopic support leg 24 can be adjusted according to the force applied to the adjustment disk 21 to improve the support effect on the adjustment disk 21.

[0042] In this embodiment, there are three telescopic support legs 24, which are evenly spaced around the circumference of the adjustment disk 21 to provide stable three-point support for the adjustment disk 21. In other embodiments, the number and position of the telescopic support legs 24 can be adjusted according to actual conditions.
