A retaining ring 12 is rotatably installed on the bottom of the support tube 11. Two electric telescopic rods 13 are fixedly installed on the lower surface of the second connecting plate 8. An inner gear sleeve 14 is fixedly installed on the bottom of the electric telescopic rod 13. A circular hole 17 is opened on the surface of the inner gear sleeve 14. The threaded rod 9 is located in the circular hole 17. The outer diameter of the threaded rod 9 is smaller than the inner diameter of the circular hole 17, which is convenient for moving the inner gear sleeve 14 on the threaded rod 9. A drill bit 15 is fixedly installed on the bottom of the threaded rod 9.

[0030] The external shape and size of the outer toothed disc 10 are matched with the internal shape and size of the inner toothed sleeve 14, and the position of the outer toothed disc 10 corresponds to the position of the inner toothed sleeve 14, so that the inner toothed sleeve 14 can be engaged with the outer toothed disc 10. The outer toothed disc 10 can be limited by the inner toothed sleeve 14 to prevent the outer toothed disc 10 from rotating on the threaded rod 9.

[0031] The working principle of the above embodiment is:

[0032] When in use, the inner gear sleeve 14 is driven upward by the electric telescopic rod 13 to separate the inner gear sleeve 14 from the outer gear disc 10, and then the outer gear disc 10 and the support tube 11 are rotated, so that the outer gear disc 10 and the support tube 11 can be moved on the threaded rod 9 until the length of the threaded rod 9 exposed to the bottom of the support tube 11 reaches the required length, and then the inner gear sleeve 14 is driven downward by the electric telescopic rod 13 to engage with the outer gear disc 10, so that the outer gear disc 10 and the support tube 11 can be limited, and then the outer gear disc 10 and the support tube 11 can be moved downward by the electric telescopic rod 13. The electric lifting rod 4 drives the first connecting plate 5 to rise and fall. At this time, the motor 6, the threaded rod 9 and the drill bit 15 rise and fall synchronously with the first connecting plate 5. The motor 6 is started, and the motor 6 drives the rotating rod 7 and the second connecting plate 8 to rotate, so that the threaded rod 9 and the drill bit 15 can rotate synchronously to drill. When the specified depth is reached, the retaining ring 12 will contact the surface of the object, thereby preventing the threaded rod 9 and the drill bit 15 from continuing to drill deeper. The support tube 11 rotates on the retaining ring 12, and the threaded rod 9 and the drill bit 15 rotate in the drilled hole.

[0033] The control method of the present invention is controlled by a controller. The control circuit of the controller can be realized by simple programming by technicians in this field. The provision of power is also common knowledge in this field. The present invention is mainly used to protect mechanical devices, so the present invention will no longer explain the control method and circuit connection in detail.
