Abstract

The invention relates to the technical field of common mechanical auxiliary equipment, and discloses an auxiliary drilling device for a hand-held electric drill. The auxiliary drilling device for thehand-held electric drill comprises a cover body, a mounting hole, a conical spring, a thin bearing, an auxiliary positioning mechanism, a transverse partition, a contact mechanism, an air pump, a transition mechanism, an air intake pipe, a single-way air guiding valve, a ring groove, an elastic sealing ring, a controlling switch, a two-foot pedal, and a tapered telescopic sleeve, wherein the mounting hole is formed in the top middle portion of the cover body; the top portion of the conical spring is fixedly mounted on the inner side of the mounting hole and extends to the inner side of the cover body; the thin bearing is fixedly mounted on the inner side of the bottom of the conical spring; the broadside of the top portion of the tapered telescopic sleeve is adhered to the inner bottom ofthe mounting hole; and the bottom inner side of the tapered telescopic sleeve adheres to the outer side of the thin bearing. According to the auxiliary drilling device for the hand-held electric drill, the purpose of assisting in the positioning and protection of a drill bit while preventing the diffusion of dust is achieved, and the dust generated by the drilling is prevented from falling on theground and causing the backfilling effect of the drilling hole.

Description

technical field [0001] The invention relates to the technical field of common mechanical auxiliary equipment, in particular to an auxiliary drilling device for a hand-held electric drill. Background technique [0002] During construction or decoration, electric drills are often used to drill holes in the ground. The drill bit of the electric drill acts strongly on the ground, causing the drilled part of the ground to be crushed and introduced into holes, but the force of this high-speed rotation is also easy to use. The generated dust is scattered in the air, which is easy to affect the working environment of the operator. Inhalation into the lungs is not good for the body. Some existing auxiliary devices for the use of electric drill bits cover the drill bit to prevent dust particles from spreading. However, this anti-diffusion method is to limit the dust particles within a certain range. After the drill bit is drilled, a large amount of dust generated is accumulated around...
