When the position needing drilling is adjusted, the drilling motor 20 starts to operate to drive the drilling shaft 17 to rotate, so as to drive the threaded block 16 to move leftwards, further continuously compress the abutting spring 15, further drive the jacking sliding block 14 to move leftwards until the jacking sliding block 14 abuts against the wall, at the moment, the jacking sliding block 14 is completely fixed, further completely fix the internal drilling shaft 17, further avoid the influence of the shaking of the drilling shaft 17 on the cracking of the wall, at the moment, the small motor 12 operates to drive the long shaft 22 to rotate, further drive the moving block 21 to move, further drive the drilling motor 20 to continuously move leftwards, so that the drilling shaft 17 can continuously drill leftwards into the wall, while the jacking sliding block 14 moves leftwards, drive the abutting block 39 and the dust suction pipe 37 to move leftwards, further drive the hinged rod 40 to move leftwards, further drive the fan shaft 50 and the fan 48 to move leftwards, until the abutting block 39 abuts against the wall, at this time, the abutting block 39 starts moving rightwards, the hinge rod 40 is driven to move, the up-down sliding 46 is driven to move downwards, the extension spring 45 is continuously stretched, the up-down sliding 46 falls into the limiting groove 53 and is limited, at this time, the dust suction pipe 37 drives the fan shaft 50 to move leftwards, the driven gear 51 and the fan 48 are driven to move leftwards, until the driven gear 51 is meshed with the driving gear 13, the driving gear 13 rotates to drive the driven gear 51 to rotate, the fan shaft 50 is driven to rotate, the fan 48 is driven to rotate, air is continuously sucked into the dust suction cavity 38, dust drilled in the drilling shaft 17 is rotated by the fan 48 and is sucked into the dust suction cavity 38, and when the dust falls into the dust collection cavity 56 through the dust suction cavity 38, the dust is continuously accumulated on the abutting door 55 due to the inclination of the dust collection box 36; when drilling is completed, the drilling motor 20 reversely operates at this time, and further drives the drilling shaft 17 to rotate, and further drives the abutting spring 15 to move rightwards, and further drives the abutting spring 15 to be continuously stretched, and further drives the abutting slide block 14 to move rightwards, and further drives the right end of the up-down sliding 46 to start moving upwards against the right end of the limit groove 53, and further to disengage from the limit groove 53, and further is influenced by the repulsive force of the tension spring 45, so that the up-down sliding 46 is restored to the initial position, and further drives the hinge rod 40 and the abutting block 39 to be restored to the initial position, and the dust suction pipe 37 and the fan shaft 50 are driven to move rightwards while the abutting slide block 14 moves rightwards, and further the fan shaft 50 is disengaged, and further the fan 48 stops rotating, at this time, the small motor 12 reversely operates to drive the long shaft 22 to rotate, and further drives the, further, the drilling shaft 17 is continuously pushed out of the hole to restore to the initial position; when the drilling is finished and the drilling height needs to be adjusted, the large motor 32 operates the driving screw 34 to rotate, and further drives the expansion plate 26 to move upwards, and further drives the lower ends of the auxiliary expansion rod 29 and the main expansion rod 28 to move in the guide chute 30, and further drives the fixed shaft 58 to move upwards in the limiting cavity 27, and further drives the abutting rod 23 to move upwards, and further drives the whole drilling body 11 to move upwards, when the drilling body 11 needs to be reversed, the large motor 32 operates the driving short shaft 33 to rotate, and further drives the abutting plate 25 to move upwards, until the abutting plate 25 abuts against the lower end surface of the drilling body 11, at the moment, the upper end surface of the abutting rod 23 is continuously away from the upper wall of the fixed cavity 24 until the lower end surface of the abutting rod 23 abuts against the bottom wall of the fixed cavity 24, at the moment, the drilling body 11 is rotated, so that the two abutting rods 23 fall into another set of symmetrical fixed cavities 24, the large motor 32 runs in the reverse direction to drive the short shaft 33 to rotate, so as to drive the tightening plate 25 to move downwards, so that the tightening plate 25 is separated from the abutting connection hole body 11, the upper end face of the abutting connection rod 23 is continuously abutted against the upper wall of the fixed cavity 24, and the hole body 11 is fixed;

when the dust in the dust collecting chamber 56 needs to be cleaned, the sliding plate 54 is slid rightwards until the upper end surface of the sliding plate 54 is not abutted to the lower end surface of the abutting door 55 any more, at this time, the abutting door 55 is opened downwards, and the dust falls out of the dust collecting chamber 56.

The invention has the beneficial effects that: the invention is applied to the punching of building walls, when the wall needing punching is punched, the jacking slide block is abutted to the wall, so that a drilling shaft can not shake during punching, thereby achieving the purpose of preventing the wall from cracking, the jacking slide block can be completely locked through the jacking mechanism, the fan is rotated through the meshing of the driven gear and the driving gear, dust caused during punching can be sucked into a dust suction cavity for placing, meanwhile, the whole device can be rotated in multiple angles and multiple directions through the steering mechanism, thereby achieving the purpose of high utilization rate, the device can be lifted or lowered through the expansion plate and the abutting rod, and the punching height can be more conveniently adjusted.

In the above manner, a person skilled in the art can make various changes depending on the operation mode within the scope of the present invention.
