When the arc-shaped movable plate 32 moves toward one end of the driving motor 71, the first cone on the bottom of the arc-shaped movable plate 32 pushes and inserts into the rotating disk. The rotating block 36 on the disk 30 pushes the rotating disk 30 to move. After completing one action, the arc-shaped movable plate 32 moves away from one end of the driving motor 71. When the first conical push block 37 at the bottom of the arc-shaped movable plate 32 is separated from the rotating block 36, the second conical push block 38 enters the bottom of the next rotating block 36, and continuously drives the rotating disk 30 to perform intermittent rotational movement, so that the second gear 25 on the second rotating shaft 31 engages to drive the first rotating shaft 24 on the rotating seat 23 to rotate.
