[0018] Furthermore, the active protrusions 6 are distributed at equal intervals at the bottom of the movable frame 5, and both ends of the active protrusions 6 form a first groove with the outer wall of the movable frame 5. Two driven protrusions 12 are provided on the outer wall of the movable wheel 10, and a second groove is formed between the two movable wheels 10. The first groove cooperates with the driven protrusions 12, and the second groove cooperates with the active protrusions 6, which facilitates the movable frame 5 to drive the movable wheel 10 to rotate through the active protrusions 6 and the driven protrusions 12.

[0019] Furthermore, the pendulum rod 11 is distributed in an inclined shape, and the pendulum rod 11 forms a rotating structure with the device housing 1 through the movable shaft 9, which facilitates further stirring after the pendulum rod 11 rotates.
