The invention discloses a financial certificate punching device, which comprises a bottom plate, an upper plate, a pressure rod, a connecting rod, a hydraulic lifting column, and a round hole. A suction cup is bonded to the bottom of the bottom plate, and a round hole is opened on the upper surface of the bottom plate. An air outlet head is installed in the round hole, and the air outlet head is connected to the air guide pipe. There is a drawer on the bottom plate, and a screw-mounted column is installed in the drawer. There is a screw-mounted hydraulic lifting column on the bottom plate. The upper plate is equipped with a screw-mounted fixing block, the pressure bar is hinged with the fixed block, the connecting rod is welded to the pressing bar, a sleeve is installed on the upper plate, and the connecting rod is connected with the upper plate through the sleeve. The end is tapered, the bottom of the connecting rod is welded with a first spring, and the upper plate is provided with a screw hand wet device. The invention is simple in structure and reasonable in design; the hydraulic lifting column can adjust the height of the upper plate, thereby adjusting the strength when punching holes, and the air outlet head and the air guide pipe can easily clean the paper scraps in the round holes.
