High-precision electric drill with dustproof function

Abstract

The invention relates to a high-precision electric drill with a dustproof function. The high-precision electric drill comprises a main body, a drill bit, a positioning mechanism and a dedusting mechanism, wherein the positioning mechanism comprises a supporting ring and two connecting assemblies; each connecting assembly comprises a fixed sleeve, a supporting rod, a friction block, a rotating rod,a turntable, a convex block and two supporting units; the dedusting mechanism comprises a cover shell, a pipeline, a cover plate, a dust collecting groove, an air pump, a connecting sleeve, a limiting ring, a filter screen and at least two permanent magnets; and each supporting unit comprises a fixed shaft and an installation sleeve. In the high-precision electric drill with the dustproof function, the depth of drilling of the electric drill can be controlled by the positioning mechanism, so that the drilling precision of the electric drill is improved; dust generated during the operation ofthe electric drill can be collected by the dedusting mechanism, so that the quantity of the dust generated during the operation of the electric drill is reduced, and the practicability of the electricdrill is improved.

Description

technical field [0001] The invention relates to the field of construction equipment, in particular to a high-precision electric drill with a dust-proof function. 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. 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. . [0003] As a kind of construction equipment, the electric drill is widely used in construction. The electric drill of the prior art will produce a large amount of dust during the drilling process. The long-term i...

Problems solved by technology

[0003] As a kind of construction equipment, electric drills are widely used in construction. The electric drills of the prior art will generate a large amount of dust during the drilling process. The long-term inhalation of dust by the operator will affect the health of the operator, not only that , the electric drill of the prior art is difficult to control the depth of the electric drill during the drilling process, which reduces the accuracy of the electric drill.
