Abstract

The invention relates to an electric tool which comprises a shell provided with a cavity in a surrounding manner, a working assembly connected with the shell and a driving assembly arranged in the cavity to drive the working assembly. An air port is formed in the shell, and the shell further comprises a dustproof cover detachably installed on the air port. The electric tool is characterized in that a positioning hole is formed around the air port, a positioning column matched with the positioning hole is arranged on the dustproof cover, and a flexible mechanism in interference fit with the positioning column is arranged in the positioning hole; and the electric tool further comprises an outer shell wrapping the shell, an injection molding channel used for being communicated with the positioning hole is formed in the shell, and the outer shell and the flexible mechanism are integrally formed in an injection molding manner through the injection molding channel. By arranging the dustproofcover matched with the air port, dust and the like are prevented from entering a machine, and the service life of a brushless angle grinder is prolonged; and the flexible mechanism is arranged in thepositioning hole, and the flexible mechanism is in interference fit with the positioning column, so that the dustproof cover and the air port are more convenient to disassemble.

Description

technical field [0001] The invention relates to an electric tool and belongs to the technical field of electric tools. Background technique [0002] The angle grinder is a power tool that is powered by electricity and drives the grinding wheel to rotate at high speed for grinding and cleaning. The internal components of the angle grinder will generate a lot of heat during the working process, so it is necessary to open an air vent on the casing to effectively dissipate heat from the electronic components on the control board. The angle grinder in the prior art is not provided with a dust cover matching the tuyeres, or even if a dust cover is provided, it is difficult to fix the dust cover with the tuyeres or to disassemble it, thereby causing inconvenient cleaning in the later stage. Contents of the invention [0003] The object of the present invention is to provide an electric tool, which is provided with a dust-proof cover and a positioning post connected with the dust...
