The power supply of the dust collector 15 can be provided by a storage battery 18 or an external power supply. The side of the storage box 17 is provided with an openable and closable box door, and the inside of the storage box 17 can be provided with a storage compartment for placing tools.

[0046] As an implementable manner, as shown in Figure 1 , Figure 2 , Figure 3 , Figure 6 As shown, the corrugated telescopic pipe 8 and the dust collecting hood 9 are structural members made of transparent materials.
[0047] Both the corrugated expansion tube 8 and the dust collection hood 9 are made of transparent materials such as transparent plastic, which makes it easy for construction personnel to observe the drilling situation of the drill bit 10 inside the dust collection hood 9 and the amount of dust generated.

The scale pointer 19 is welded or bonded to the lower end of the stop block 24. Initially, the scale pointer 19 corresponds to the zero mark value of the scale ruler 20. During drilling, the guide rod 7 moves backward (in the opposite direction to the drill bit 10 drilling into the wall), causing the scale pointer 19 to move backward along the scale ruler 20 from the zero mark value. The scale value of the scale pointer 19 on the scale ruler 20 is the same as the depth to which the drill bit 10 has penetrated into the wall. By directly observing the scale value of the scale pointer 19 on the scale ruler 20, the construction personnel can quickly and accurately determine the depth to which the drill bit 10 has penetrated into the wall, that is, accurately determine the drilling depth.
