The middle part of the drilling machine 4064 is rotatably connected to one side of the connecting seat 4063, and the reduction motor 4065 is installed on the other side of the connecting seat 4063. The output end of the reduction motor 4065 passes through the connecting seat 4063 and is connected to the drilling machine 4064.

[0021] Specifically, when the slider 403 slides on the outer periphery of the slide rail 402, the stepper motor 405 drives the threaded rod 401 to rotate, and the movable seat 404 drives the drilling assembly 406 to move left and right.
