Safety device for guidance of electric drill

Abstract

The invention provides a safety device for guidance of an electric drill. The safety device comprises a locating pressing part, a pressing nut, a cover, a screw, a guiding sliding part, a compression spring, a spring positioning part, a protective cover and an arc-shaped cushion. The safety device disclosed by the invention is capable of rapidly playing a clamping and fixation effect; the guiding sliding part is capable of realizing slow and stable drilling by the effect of spring force during drilling and is also capable of realizing rapid and stable exiting by the effect of the spring force during exiting, so that a drill is effectively prevented from breakage, and the safety and reliability of the electric drill in use are improved; the protective cover is made from transparent organic glass, so the feed condition of the drill can be observed at any time; arc-shaped grooves are formed in the two sides of the bottom, so the perpendicularity when the drill is in contact with an arc-shaped working surface is guaranteed; the circular surface of the bottom is a plane, so the perpendicularity when the drill is in contact with a planar working surface is guaranteed; thus, the perpendicularity of the drill in work is guaranteed, a quite good guidance and location effect is played, the work efficiency is improved, and the stability in use is guaranteed.

Description

technical field [0001] The invention relates to the technical field of electric drill guidance, in particular to a safety device for electric drill guidance, and in particular provides a device that can automatically guide and provide safety protection when the electric drill is in use. Background technique [0002] An electric drill is a drilling tool that uses electricity as power. It is a conventional product in electric tools, and it is also the most demanded electric tool product. [0003] The working principle of the electric drill is that the motor rotor of the electromagnetic rotary or electromagnetic reciprocating small-capacity motor performs magnetic field cutting and works, drives the working device through the transmission mechanism, and drives the gear to increase the power of the drill bit, so that the drill bit scrapes the surface of the object and penetrates the object better. .

AI Technical Summary

Problems solved by technology

[0004] At present, electric drills on the market are not easy to maintain verticality during use, and the drill bit is easy to break and easily hurt people. Therefore, a positioning and guiding device that can not only maintain verticality but also play a protective role is particularly important.
