The top of the stirring rod is also fixedly connected with a connecting buckle 6, and the stirring rod is a mature product in the prior art. When the water-based polyurethane preparation equipment needs to be cleaned, the tank cover 3 is first opened, and the tank cover 3 and the stirring rod are taken out. At this time, the threaded rod 8 is rotated, and the rotation of the threaded rod 8 will drive the threaded plate 9 to move upward. At this time, the movement of the threaded plate 9 will pull the pull rod 10 and push the push rod 12. The lateral movement of the push rod 12 will push the cross plate 13 to move right. At this time, the movement of the cross plate 13 will compress the spring 14. At the same time, the movement of the cross plate 13 will drive the connecting plate 16 to move, thereby driving the positioning block 11 on the right to move. The pull rod 10 will pull the positioning block 11 on the left to move horizontally. At this time, The two positioning blocks 11 move to the side away from each other so that the connecting buckle 6 is unlocked. At this time, the stirring rod can be removed and the connecting buckle 6 on the top of the scraper 7 can be inserted into the fixed box 5. At this time, the threaded rod 8 is rotated, and the rotation of the threaded rod 8 will drive the threaded plate 9 connected by the thread to move down and reset. When the threaded plate 9 moves, it will drive the pull rod 10 and the push rod 12 to reset. The pull rod 10 will drive the positioning block 11 on the left to reset. At the same time, the spring 14 loses its restriction and pushes the connecting plate 16 to reset the positioning block 11 on the right. At this time, the two positioning blocks 11 move to the side close to each other and fix with the connecting buckle 6 to fix the scraper 7. At this time, the tank cover 3 is fixed on the processing tank 2.
