When changing materials, the operator can rotate the fastening screw 14 at the lower end of the displacement frame 3 to move the anti-slip plate 15 at one end of the fastening screw 14 away from the mounting plate 4, so that the displacement frame 3 can slide on the mounting plate 4. Then, the displacement frame 3 is dragged by the pull rod 12 to move the whole displacement frame to directly above the collection hole, thereby removing and collecting the original residual material.

[0026] The scraper 2 is integrally fitted to the inner wall surface of the material cylinder 1. A connecting plate is fixedly installed on the upper surface of the scraper 2, and an operating handle 9 is fixedly installed on one end of the connecting plate.
