By rotating the fixing sleeve 6 threadedly connected to the outer surface of the fixing column 5, the fixing sleeve 6 rotates with the fixing ring 7, and the fixing sleeve 6 drives the fixing ring 7 to move up and down outside the fixing column 5. At this time, the fixing ring 7 rotates with the fixing bracket 8, and the fixing ring 7 drives the fixing bracket 8 to rotate with the clamping plate 9.
