electric drill dust cover

Abstract

The invention relates to an electric drill dust cover which comprises a cover body, an electric drill installation pipe and a stretchable neck. The electric drill dust cover is characterized in that the cover body is a hollow thin-wall frustum, a drill bit extending hole is formed in the upper bottom face of the frustum, the electric drill installation pipe is arranged on the lower bottom face of the frustum, the corrugated stretchable neck is installed inside the electric drill installation pipe, the stretchable neck can be compressed under the effect of pressure, one end of the stretchable neck is connected with the electric drill installation pipe, and the other end of the stretchable neck is provided with an L-shaped step. According to the electric drill dust cover, the working area of an electric drill can be closed, cuttings and dust are collected, and the problems that cuttings are scattered and fly out and dust is blown are avoided.

Description

technical field [0001] The invention belongs to the field of hardware tools, in particular to an electric drill dust cover. Background technique [0002] The electric drill is a commonly used tool, but there are problems of flying debris and dust during the drilling process. The debris generated by the drilling is scattered on the ground and is not easy to clean up. Some sharp debris will hurt the human body when flying out. The flying dust not only easily distracts the operator, but also affects the health of the operator if the dust is inhaled for a long time. Therefore, the debris and dust generated by drilling are a problem that needs to be solved urgently. [0003] Although the Chinese patent CN201534233 proposes a dustproof cover for an electric drill, it specifically discloses the following technical features: comprising a telescopic tube 3, one end of the telescopic tube 3 is connected to a semi-circular cover 2, a dust collector 1 is arranged on the semi-circular co...

Problems solved by technology

Therefore, when using the electric drill dust cover of this patent, the drill bit cannot expose the electric drill dust cover, and the operator can only: align the drill bit with the drilling position by feeling; The intersecting relationship of the centerline at the drill hole is roughly aligned with the drill bit. However, the dust cover cannot be accurately assembled with the electric drill. It is estimated based on the intersection relationship between the circular front surface and the centerline, and its positioning accuracy is poor; or in When aiming, use the other hand to compress the telescopic tube first and then expose the drill bit for aiming

As a result, it is impossible to align the drill bit with the part to be drilled more conveniently and accurately
