A triangular scraper 4 is arranged at the lower end inside each C-shaped groove 101. When there are sticky sundries on the ground that are difficult to detach, the PVA glue cloth 1 and the air cushion 2 are compressed forcefully, so that the triangular scraper 4 extends out of the C-shaped groove 101 to contact the ground. The sundries adhered to the ground are scraped off by the triangular scraper 4 during mopping and washing. The upper end of each movable rod 402 respectively passes through the middle of the fixed limit ring 304 at the lower end inside the fixing cylinder 301 and extends into the circular groove 302 inside to be fixedly connected with a movable limit ring 403. The outer end face of the movable limit ring 403 is attached to the side end face of the circular groove 302 inside the fixing cylinder 301, so that when the triangular scraper 4 is compressed, the movable rod 402 is inserted into the circular groove 302 for buffering. The stability of the upper end of the movable rod 402 moving inside the circular groove 302 is maintained through the movable limit ring 403. A spring 303 is disposed inside the circular groove 302 of the circular groove 302.
