Abstract

The invention provides an angle grinder. The angle grinder comprises an angle grinder body, wherein the angle grinder body comprises a holding part, a deceleration gear part and an abrasive disc; a driving motor is arranged in the holding part; in addition, the holding part is provided with a main shaft connected to the deceleration gear part; after the deceleration gear part decelerates the rotating output of the driving motor, the decelerated rotating output is transmitted to the main shaft; the abrasive disc is arranged at the end part of the main shaft; the periphery of the abrasive disc is wrapped through an abrasive-disc cover; a water pipe is arranged in the angle grinder body; the water pipe is inverted in the angle grinder body from the tail end of the holding part, and enters the main shaft; the outlet of the water pipe is positioned at the center of the abrasive disc. According to the angle grinder disclosed by the invention, water flows to the abrasive disc through the water pipe, and water is uniform on the abrasive disc and the surface of a ground object; the working manner of an angle grinder is changed from dry and coarse grinding into water-supply coarse grinding, so that the dust is effectively prevented from flying and scattering, and the harm of dust to operators is reduced; in addition, the abrasive-disc cover wraps the abrasive disc, so that the dust is effectively prevented from flying and scattering, and water is effectively prevented from splashing.

Description

technical field [0001] The invention relates to an electric tool, in particular to an angle grinder for preventing dust from flying. Background technique [0002] The electric angle grinder is a tool for grinding, cutting, rust removal and polishing of metal components using high-speed rotating sheet grinding wheels, rubber grinding wheels, wire wheels, etc. [0003] Angle grinders are suitable for cutting, grinding and brushing metal and stone, and for models equipped with electronic controls, grinding and polishing can also be performed if suitable accessories are fitted to these machines. [0004] During the working process of the angle grinder, a large amount of dust is scattered, which seriously affects the health of the operator. Contents of the invention [0005] An object of the present invention is to provide an angle grinder that prevents dust from flying. [0006] In order to achieve the above object, the angle grinder provided by the present invention include...
