[0010] Furthermore, a drilling motor is fixedly arranged on the top of the lifting plate, and an output end of the drilling motor passes through the lifting plate and is fixedly connected to the drill bit.

[0011] Furthermore, a lifting screw and a guide shaft are provided inside the U-shaped plate, the lifting screw passes through the lifting plate and is threadedly connected to the lifting plate, and the guide shaft passes through the lifting plate and is slidably connected to the lifting plate.

[0012] Furthermore, the lifting screw is rotatably arranged on the inner side of the U-shaped plate, the guide shaft is fixedly arranged on the inner side of the U-shaped plate, a lifting motor is fixedly arranged on the top of the U-shaped plate, and the output end of the lifting motor passes through the U-shaped plate and is fixedly connected to the lifting screw.

[0013] Furthermore, a positioning cylinder is symmetrically arranged on the top of the first positioning seat, and a positioning plate is fixedly arranged on the output end of the positioning cylinder.

[0014] Furthermore, a first positioning hole is formed through the top center point of the positioning box, and second positioning holes are formed through the middle of the first positioning seat and the second positioning seat, and the first positioning hole and the second positioning hole are both located directly below the drill bit.
