When an external force is applied to the movable limiting block 22, the elastic member 23 is compressed, the movable limiting block 22 is pushed into the groove by the hinge point center of the movable limiting block 22 and the bottom wall of the groove, and at this time, the upper sliding sleeve 21 can slide up and down through the position of the movable limiting block 22. When the upper sliding sleeve 21 slides upwards from the fixed limiting block 22, an external force is applied to the movable limiting block 22, so that the upper sliding sleeve 21 can smoothly slide over the position of the movable limiting block 22, then the applied external force is released, and the movable limiting block 22 returns to the initial position again under the action of the elastic piece 23, namely the outside of the second rotating shaft 6, so as to limit the upper sliding sleeve 21; similarly, when the upper sliding sleeve 21 needs to slide downwards, an external force is applied to the movable limiting block 22, and the external force is pushed into the groove, so that the upper sliding sleeve 21 can smoothly slide over the position of the movable limiting block 22 and slide downwards to the upper side of the fixed limiting block 20.

The bottom of the guide cylinder 4 is only contacted with the inner bottom of the dispersion box 2, so that the guide cylinder does not rotate along with the dispersion box 2 and the stability of the guide cylinder 4 is not influenced. The diameter of the opening at the upper end of the dispersing box 2 is larger than the maximum diameter of the material guide cylinder 4, so that the dispersing box 2 can drive the material guide cylinder to contract to the shortest.
