the rotation of the rotating rod 37, the rotating disk 36 is driven to rotate for a certain displacement through the rotating slot 361 provided on the rotating disk 36, then the incomplete gear 49 is separated from the third rack 46 and then moves continuously, the circular roller provided below the incomplete gear 49 contacts with the second wedge-shaped block 47 on the sliding frame 40, and then presses the wedge-shaped block, so that the sliding frame 40 moves along the sliding slot 2401 in the direction of the third rack 46, and thus the third rack 46 is driven to move in the direction away from the incomplete gear 49, the fourth rack 48 moves in the direction close to the incomplete gear 49, so that the incomplete gear 49 can be engaged with the fourth rack 48, and in conclusion, when
