The driving groove 31 is horizontally arranged. The driving shaft 30 is located in the driving groove 31. When the driving gear 28 rotates, the driving shaft 30 moves in the driving groove 31 and drives the driving rod 29 to move up and down. The lower end of the driving rod 29 is provided with an abutment groove 32 with a gradually changing depth opposite to the side wall of the mounting plate 26, and the abutment groove 32 extends in the height direction.
