[0003] During building renovation or maintenance, it is often necessary to remove the plaster layer on the surface of bricks. Traditional removal methods are mostly manual operations, using a scraper, but the scraper needs to maintain appropriate scraping force as much as possible. Long-term scraping operation is prone to fatigue, unstable force can easily damage the brick surface, and the efficiency will gradually decrease.
[0004] Therefore, the prior art needs to be improved. Utility Model Content
[0005] The technical problem to be solved by the utility model is that the existing method for removing the plaster layer is inefficient and easily damages the surface of the brick.
