[0029] Working principle: When using this device, the power of the external power grid and mobile power supply is connected to this device through the external cable 3, and the power is rectified by the electric control box 1 and input into the single-chip processor 4. The staff holds the electric control box 1 in one hand and the vacuum pump 12 in the other hand, and presses the dustproof cylinder 11 against the position to be drilled. The hand holding the electric control box 1 inputs the work instruction on the operation panel 5, and the single-chip processor 4 controls the motor 8 to start, and the motor 8 drives the drill rod 10 to rotate, and the drilling operation begins. The dust generated during the drilling process gathers in the dustproof cylinder 11, and then the vacuum pump 12 is started. The vacuum pump 12 generates a pressure difference, and the air in the dustproof cylinder 11 is pressurized together with the dust through the guide tube 15, and sent to the filter bag 13 for filtration. The dust remains in the filter bag 13, and the air is discharged into the air, completing the centralized treatment of the dust.
