Inner wall surface polishing device for house building engineering

The utility model provides an interior wall surface polishing device for house building engineering, which comprises a shell, a connecting frame, a suction pipe, a waste tank, an outer cylinder and a grip, the connecting frame is fixedly mounted at the bottom end of the shell, compared with a traditional interior wall surface polishing device, the interior wall surface polishing device can quickly clean impurities and dust on the surface of an interior wall during use, and the interior wall surface polishing device is convenient to use. And impurities can be sucked after cleaning is completed, workers do not need to manually clean waste materials after machining is completed, the overall working intensity is greatly reduced, dust and impurities are prevented from influencing work of the workers, the overall machining quality is more perfect, the overall length of the equipment can be rapidly adjusted, and the machining efficiency is improved. According to the wall surface machining device, the wall surfaces w
