[0014] 2. The internal motor drives the screw to rotate through the rotating mechanism, which moves the movable frame. After the extrusion wheel disengages from the extrusion groove, the rotating ring can descend vertically to complete the disassembly from the lifting plate. Pressing the positioning block disengages it from the positioning hole, and the mounting block and drilling rod can be disassembled through the disassembly port, which facilitates equipment maintenance and component replacement.

[0015] 3. In the positioning mechanism, the extrusion wheel enters the extrusion groove to prevent the rotating ring from moving vertically and detaching from the lifting plate; the extrusion mechanism uses the elastic potential energy of the spring to squeeze the positioning block part out of the extrusion groove and send it into the positioning hole, so as to realize the positioning and installation of components such as the mounting block and ensure the stability of the structure during drilling.
