[0019] As Figure 1 and Figure 2 shown, a rectangular mounting plate 7 is also arranged on the upper surface of the L-shaped support block 6. A driving motor 8 is arranged on one side of the L-shaped support block 6. Fixing plates are arranged on both sides of the driving motor 8, and the other ends of the fixing plates are connected to the vertical surface of the L-shaped support block 6. A rotating rod 9 is also arranged on the circular surface of the driving motor 8, and the rotating rod 9 also penetrates through the L-shaped support block 6. A gear column 10 that is penetrated is arranged at the end of the rotating rod 9 away from the driving motor 8. A toothed plate 11 is arranged directly below the gear column 10, and the lower surface of the toothed plate 11 is connected to the upper surface of the rectangular moving plate 2.
