The mixture rotates spirally in the vertebral tube 1 to perform swirl operation. When the swirl angle needs to be changed, the operator can turn the adjustment handwheel 13. The rotation of the adjustment handwheel 13 drives the rotation shaft 7 to rotate. The rotation of the rotation shaft 7 drives the blade plate 9 to rotate. The blade plate 9 adjusts the angle to change the direction of the water flow through the drainage groove 10. When the adjustment handwheel 13 rotates, it drives the inclined protrusion 19 to be subjected to force, so that the surface of the inclined protrusion 19 is aligned with the triangular groove. 15 frictionally contacts the inner wall, and the compression spring 18 becomes shorter, thereby releasing the current plug-in state for repositioning.
