When the fixed ball enters the movable groove, the side of the fixed ball contacts the lower end surface of the engaging block. Since the side of the fixed ball is curved, it resists the engaging block, so that the engaging block is squeezed and retracts into the fixed groove through the engaging block. At this time, the engaging block squeezes the push spring, so that the push spring is in a contracted state; when the fixed ball continues to extend into the movable groove, the engaging block loses its fixed position. The ball contacts, so the locking block is pushed by the contracted pushing spring, so that the upper end surface of the locking block fits with the lower end surface of the fixed ball, thereby fixing the scraper; by arranging a movable ball on the outside of the fixed block, the movable ball can be manually pushed, so that the movable ball moves along the top of the fixed block, and when the movable ball fits with the bottom side of the fixed ball, the movable ball also contacts the locking block, so that the scraper is separated from the fixed mounting seat. The present invention has a simple structure and is easy to operate. The fixed ball and the movable ball are manually moved, thereby facilitating the installation and disassembly of the scraper.
