[0018] Preferably, the connection between the drill bit 1 and the drill body 2 can be either a clamping type or a direct insertion type. The clamping type uses a chuck to secure the drill bit to the drill body. The chuck consists of a chuck body, a locking ring, and a locking nut. There are two types of clamping connection: manual and automatic. The manual clamping type requires manually rotating the locking ring to clamp the drill bit onto the drill body. The automatic clamping type only requires pressing a button, and the chuck automatically clamps the drill bit. The direct insertion type involves directly inserting the drill bit into the drill body.

[0019] To make the structural design of the present invention more reasonable, as a preferred embodiment, the lifting mechanism 7 includes a base 71, a linear actuator 72, and a connecting frame 73. One side of the base 71 is integrally formed with the machine tool connector 8 or fixed by bolts. The lower end of the linear actuator 72 is fixed to the base 71 by bolts.

[0022] The upper housing 51 and the lower housing 52 are fixed together by bolts. The right end face of the lower housing 52 is integrally formed with the left end of the connecting shaft 6 or fixed together by bolts.

[0023] The left end of the support rod 3 is fixed to the drill body 2 by bolts, and the right end of the support rod 3 is integrally set with the left end face of the adjustment plate 4; a camera 11 is set at the lower left end of the support rod 3, and the camera 11 is fixed to the support rod 3 by screws.

[0024] The connecting shaft 6 is equipped with a first control switch 12 and a second control switch 13. Both the first control switch 12 and the second control switch 13 are fixed to the connecting shaft 6 by screws. The first control switch 12 is connected to the electric drill body 2 by a wire and controls the drill bit 1 to rotate or stop. The second control switch 13 is connected to the linear actuator 72 by a wire and controls the extension or retraction of the telescopic rod 721 of the linear actuator 72 by the second control switch 13.

[0025] Preferably, the linear actuator 72 is an existing electric linear actuator.

[0026] The fastener mounting base 9 is fixed to the upper end of the upper housing 51 by screws.

[0027] In practical applications, the lifting mechanism 7 can be installed on the tailstock of an existing machine tool via the machine tool connector 8. First, the telescopic rod of the linear drive 72 is adjusted to a suitable position by controlling the second control switch 13. Then, the limit bolt 10 is loosened, the adjusting disc 4 is rotated, and the angle of the drill bit 1 is adjusted to the required machining position. Then, the limit bolt 10 is tightened so that the head of the limit bolt 10 locks the knurled part 42 at a partial position. Next, the drill bit 1 is started by the first control switch 12. Finally, the telescopic rod of the linear drive 72 extends and retracts, thereby driving the drill bit 1 to rise and fall to perform drilling work. The structure is reasonably designed, small in size, convenient for drilling operation, reliable in operation, and highly practical. The above embodiments are only used to further illustrate the present invention and should not be construed as limiting the scope of protection of the present invention.
