A handwheel 7 is provided at one end of the connecting rod 6 located outside the workbench 1. The screw rod 5 is rotated by turning the handwheel 7, thereby driving the slider 4 and the movable column 32 to move, which is convenient for operation.

[0028] A rotating shaft 9 is provided on the clamping member 2, and the rotating shaft 9 is inserted in the mounting column 3. A bearing is provided between the mounting column 3 and the rotating shaft 9. A semicircular plate 10 is provided on the top of the mounting column 3.
