A disc is provided on the base plate, and the disc is provided with a drilling through hole and a plurality of blind holes. The axes of the drilling through hole and the plurality of blind holes are located on the same circle. The lifting component is provided on the base plate, and the rotating component is provided on the lifting component. The rotating axis of the rotating component is coaxial with the disc, and the drilling component is provided on the rotating component.
