[0041] Working principle: When scraping operation is required, the device is first moved to the corresponding position so that the scraper 202 can contact the outer wall surface, and the motor and fan 402 are started, so that the slide plate 106 can move up and down with the scraper 202, and then the cement mortar and paint on the outer wall surface are scraped, so that the dust cover 405 can absorb the dust-containing air from the outside into the collection box 401. Due to the limiting effect of the filter, the dust remains inside the collection box 401, and the dust-free air is discharged through the output end of the fan 402. When grinding operation is required, the device is rotated so that the grinding wheel 303 can contact the outer wall surface, and the high-speed motor, motor and fan 402 are started to realize the grinding operation. The protective component isolates the dust generated during grinding from the external environment to avoid affecting the external working environment, and has good practicality.
