[0012] Furthermore, a non-slip pad is bonded to the bottom of the pressing plate.

[0013] The beneficial effects of the utility model are:

[0014] 1. Clamp the flange by bringing multiple clamping plates together and push the flange toward the center of the operating table, so that the center of the flange is aligned with the center of the positioning plate, so as to position the flange and realize positioning drilling.

[0015] 2. The pressure ring is driven to move downward under the threaded connection of the second screw rod, thereby pushing the pressure plate downward, and then the pressure plate is pressed on the flange, thereby further fixing the flange and improving the fixing effect of the flange.
