[0014] The side of the overall pusher frame 13 facing the stepping drive device 14 is connected to the power side plate 16 through a connecting rod 19. The stepping drive device 14 is specifically a stepping motor. The stepping motor is fixed to the motor mounting plate 17 and connected to the corresponding nut structure of the power side plate 16 through a screw rod 18.
