When the clamping point of the pressure rod 12 and the supporting seat 10 is adjusted for displacement, the fixing seat 5 can be first fixed to the corresponding point on the workbench 1 by screws. Then, when it is necessary to further accurately adjust the displacement of the clamping point of the pressure rod 12 and the supporting seat 10, the mounting seat 4 can be manually rotated, so that the mounting seat 4 drives the first connecting shaft 7 to rotate through the displacement block 6 and the second connecting shaft 19.
