Abstract

The invention discloses a sound-reducing electric drill. The sound-reducing electric drill comprises a drill bit, an electric drill, a handlebar and a handle which are connected in order; the upper part of the electric drill is equipped with a blocking opening, and the middle part of the electric drill is equipped with an upper handle and a lower handle; the upper handle and the lower handle are fixed on an outer layer cover, and an inner layer cover places in the outer layer cover; the inner layer cover sleeves on the outer shell of the electric drill; the middle part of the outer layer cover and the inner layer cover is provided with an anti-shock strip, the left bottom parts of the outer layer cover and the inner layer cover are fixed with suction disks, and the suction disks are sucked on the wall. Two covers of the outer layer cover and the inner layer cover adopt a double-layered structure, and the middle of the double layers is hollow, and the outer layer cover and the inner layer cover are made of stainless steel and in the shape of round; the anti-shock strip is made of sponge material. The sound-reducing electric drill coats the drill bit part of the electric drill by the outer layer cover and the inner layer cover, and the anti-shock strip is placed in the middle of two layers; the handle is installed on the outer layer cover, and noise of the electric drill can be reduced in use by pressing the handle on the outer layer cover and fixing the suction disks on the wall; and thereby, the noise pollution for house decoration is reduced, and people cannot be troubled by noise of house decoration.

Description

1. Technical field [0001] The invention relates to a tool, in particular to a sound-absorbing electric drill in which an outer cover and an inner cover are installed on the electric drill. 2. Background technology [0002] Nowadays, electric drills must be used to decorate houses, but the noise of electric drills is very loud, which makes the whole building uneasy. There is no anti-noise equipment for electric drills, so as long as there is a house for decoration in the building, the noise pollution will be very large. 3. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies of the prior art and provide a sound-absorbing electric drill in which an outer cover and an inner cover are installed on the electric drill. [0004] The technical solution adopted by the present invention to solve the technical problem is: a sound-absorbing electric drill, including a drill bit, an electric drill, a handle, and the handles are connect...
