Handheld automatic dust collection wall surface polishing device

Abstract

The invention discloses a handheld automatic dust collection wall surface polishing device. The handheld automatic dust collection wall surface polishing device comprises a box body, wherein a cavitywith an opening in the right side is formed in the box body; two auxiliary boxes which are symmetrical left and right are fixed on the inner wall of the upper side and the inner wall of the rear sideof the cavity; auxiliary cavities are formed in the auxiliary boxes; and the inner walls of the auxiliary cavities are rotatably connected with two spline sleeves which are symmetrical relative to thediagonal lines of the auxiliary boxes. The handheld automatic dust collection wall surface polishing device is manually pushed against a wall, so that the wall is polished; the polishing mode that the diameters are different and the polishing directions are opposite is adopted for polishing the plane of the wall, so that the wall is fully polished; and the handheld automatic dust collection wallsurface polishing device has a function of polishing a right-angle wall corner, and also has a function of collecting floating dust and lime. The handheld automatic dust collection wall surface polishing device is simple and practical, and is convenient to polish.

Description

technical field [0001] The invention relates to the field of grinding devices, in particular to a hand-held automatic dust-absorbing wall grinding device. Background technique [0002] Workers will encounter walls in different situations when they are polishing the walls. For example, some walls have a small bump, and the rigid grinder is easy to be damaged, and one-way grinding is easy to leave circles on the wall. The imprint is not very beautiful, and the existing grinding devices are all round, which cannot be used for grinding right-angled corners. Manual grinding is required, and the existing grinding device needs to be followed by a vacuum cleaner, which is extremely inconvenient. The existing wall grinding device does not have the function of polishing the plane at multiple angles and adapting to right-angled wall corners. A hand-held automatic dust-absorbing wall grinding device described in the present invention can solve the above problems. Contents of the inven...
