When our factory processes large workpieces with holes on all sides (Fig. 1), it is difficult to load and unload the original drill.

By lifting the clamping plate 2 by hand, the workpiece can be pushed to the drilling position, the clamping plate 2 is lowered, and the hook plate 4 is pulled and hooked. Hold the pin on the clamp 2, tighten the screw 3, and then press the eccentric handle 8 to clamp the workpiece. When removing the workpiece, loosen the screw 3
