They are widely used in the reinforcement of building beams, plates, columns, walls, etc., decoration, wall installation, brackets, rails, billboards, air conditioner outdoor units, guide rails, satellite receivers, elevators, steel structure workshops, etc. During the installation process, electric drills are needed to drill holes in the wall. The dust generated during the drilling process will affect the workers.

[0003] The existing dust-proof device is generally an elastic cone-shaped structure made of rubber. The existing dust-proof device is generally opaque and not fixed, and may swing when the staff is working, thereby affecting the work of the staff.

[0004] For example, a dust-proof device for an electric drill disclosed in Chinese patent CN217728028U is provided by fixing a circular fixing part on the main body of the electric drill, and then installing a telescopic part on the circular fixing part, and the telescopic part can be telescoped back and forth. A transparent dust cover can be installed on the telescopic part, and a dust collection box can be provided at the bottom of the transparent dust cover. When the electric drill needs to drill a hole in the wall, the transparent dust cover can be pressed against the wall first, because the transparent dust cover is transparent, and the staff can easily observe the position where the hole needs to be drilled, and then start drilling. One end of the dust collection box is a slope, which can make larger particles generated by drilling slide into the dust collection box to avoid affecting the drilling work of the staff.

[0005] However, it is inconvenient to install and disassemble the dustproof device during use, which makes the device inconvenient to use.

[0006] For this reason we urgently need to provide a kind of electric drill dustproof device that is easy to install. Utility Model Content
