[0021] The specific implementation process of this embodiment is as follows:
[0022] During use, first drive the bracket 13 to flip on the telescopic rod through the second electric cylinder 16 so that the laser pointer 17 and the telescopic rod are on the same straight line. Then push the base 1 to move so that the light spot projected by the laser pointer 17 on the ceiling is aligned with the point on the ceiling where drilling is required. Then drive the bracket 13 to flip through the second electric cylinder 16 so that the drilling mechanism and the telescopic rod are on the same straight line. Then start the drilling mechanism and the lifting mechanism to drive the drilling mechanism to move upward to drill a hole with the required depth on the ceiling. The operation is simple and convenient, without the need for workers to use a drill to work at height, and the drilling efficiency is higher.
[0023] Specifically combined with Figure 1 and Figure 3 , in an embodiment of the present utility model, the telescopic rod includes a sleeve 3. The top end of the sleeve 3 is slidably penetrated with an inner rod 7. The outer wall of the sleeve 3 near the top end is penetrated with a hand-tightening bolt 8 through a threaded hole. A plurality of positioning holes 9 are opened on the outer wall of the inner rod 7 along its length direction. The positioning holes 9 are adapted to the hand-tightening bolt 8.
[0024] By matching the hand-tightening bolt 8 with different positioning holes 9, the length of the inner rod 7 extending out of the sleeve 3 can be adjusted, and the inner rod 7 and the sleeve 3 can be locked, so that the device can be applicable to ceilings of different heights, greatly reducing the limitations of the use of the device.
[0025] Specifically combined with Figure 3, on the basis of the previous embodiment, further, a guide groove 10 is provided on the outer wall of the inner rod 7, and a guide block 11 is fixedly connected to the inner wall of the top opening of the sleeve 3, and the guide block 11 is located in the guide groove 10.
[0026] Through the cooperation of the guide groove 10 and the guide block 11, it can play a guiding role in the movement of the inner rod 7 on the sleeve 3, so as to improve the stability of the movement of the inner rod 7 on the sleeve 3, and at the same time avoid relative rotation between the inner rod 7 and the sleeve 3.
[0027] Specifically combined with Figure 1 , in an embodiment of the present invention, the lifting mechanism includes a first electric cylinder 4 fixedly installed on the top of the base 1. The push rod end of the first electric cylinder 4 is fixedly connected with a support plate 5. A U-shaped frame 2 is slidably sleeved on the outer wall of the sleeve 3. The bottom end of the U-shaped frame 2 is fixedly connected with the base 1. The bottom end of the sleeve 3 is fixedly connected with the support plate 5. A plurality of guide rods 6 are slidably penetrated through the top of the U-shaped frame 2, and the bottom ends of the guide rods 6 are fixedly connected with the top of the support plate 5.
[0028] By starting the first electric cylinder 4, the support plate 5 can be driven to move up and down, so as to realize the lifting of the telescopic rod. Through the cooperation of the guide rods 6 and the U-shaped frame 2, the stability of the up and down movement of the support plate 5 and the telescopic rod can be effectively improved.
[0029] Specifically combined with Figure 1 and Figure 2 , in an embodiment of the present invention, the cylinder body end of the second electric cylinder 16 is hinged to the outer wall of the inner rod 7 through a hinge seat, the push rod end of the second electric cylinder 16 is hinged to the bracket 13, the top end of the inner rod 7 is fixedly connected with a connecting seat 12, a pin shaft is fixedly penetrated through the outer wall of the connecting seat 12, the bracket 13 is rotatably sleeved on the pin shaft, an arc-shaped groove 14 centered on the pin shaft is provided through the outer wall of the connecting seat 12, and a positioning pin 15 is arranged in the arc-shaped groove 14, and the positioning pin 15 is fixedly connected with the bracket 13.
[0030] Starting the second electric cylinder 16 can drive the bracket 13 to rotate relative to the connecting seat 12, so that the drilling mechanism or the laser pen 17 faces upward. Through the cooperation of the arc-shaped groove 14 and the positioning pin 15, the flipping angle of the bracket 13 on the connecting seat 12 can be limited, so as to more conveniently position the orientation of the drilling mechanism and the laser pen 17.
[0031] Specifically combined with Figure 1 and Figure 2 , in an embodiment of the present invention, the drilling mechanism includes a frame 18 fixedly connected with the bracket 13. A motor 19 is fixedly installed inside the frame 18. The output shaft of the motor 19 passes through the frame 18 and is fixedly connected with a drill chuck for fixedly clamping a drill bit 20.
[0032] Furthermore, the outer wall of the frame body 18 is fixedly connected with a cylinder body 21. The outer wall of the cylinder body 21 is fixedly sleeved with a rubber corrugated cover 22.

The outer wall of the cylinder body 21 is fixedly communicated with a dust suction pipe 23, and the dust suction pipe 23 is communicated with a vacuum cleaner through a hose.
[0033] By adopting the above scheme, the utility model starts the motor 19 to drive the drill chuck and the drill bit 20 to rotate, and then starts the lifting mechanism to drive the frame body 18 to move upward, so that the drill bit 20 can be used to drill holes in the ceiling. During the upward movement of the frame body 18, the top end of the rubber corrugated cover 22 will contact the ceiling prior to the drill bit 20, so as to collect the dust generated during the drilling process to prevent the diffusion of dust. By starting the vacuum cleaner, the dust collected in the rubber corrugated cover 22 can be sucked out through the hose and the dust suction pipe 23.
[0034] Specifically combined with Figure 1 In an embodiment of the utility model, the top of the base 1 is provided with a plurality of screw rods 25 through threaded holes in a matching manner.

A spirit level 28 is fixedly installed on the top of the base 1, and the telescopic rod is perpendicular to the top surface of the base 1.
[0035] Before drilling, the screw rods 25 are rotated through the handwheels 26 so that the respective support plates 27 contact the ground and the universal wheels 24 are separated from the ground, thereby providing stable support for the base 1 to improve the stability of the base 1 during the drilling process and then improve the hole forming quality. By observing the scale of the spirit level 28 and finely adjusting the distance between the respective support plates 27 and the base 1, the levelness of the base 1 can be adjusted to ensure the accuracy of the drilling angle.
