[0042] The working principle of the present invention is as follows:

[0043] Before the electric hand drill starts drilling, first dock the suction head of a household vacuum cleaner with the interface 101 on the vacuum cover 1 of the dust collector; then place the dust collector at the position where the hole needs to be drilled. At this time, the sealing gasket 2 and the sealing ring 3 surround the position where the hole needs to be drilled, and the axial center of the through hole 105 is aligned with the drilling position; then start the vacuum cleaner. At this time, under the action of the vacuum cleaner, a negative pressure is formed in the annular cavity 102 on the vacuum cover 1 of the dust collector, so that the dust collector is adsorbed on the drilling surface; then the drill bit on the electric hand drill is passed through the hole on the fixing plate 7 and the through hole 105 and aligned with the drilling position; then rotate the adjusting ring 6 to bring the dustproof brush 5 close to the drill bit; finally, start the electric hand drill and start drilling; a large amount of waste chips generated during drilling are continuously sucked away along the through hole 105 and the suction cavity 103 by the vacuum cleaner.
