The conveying device comprises a first conveying section, a second conveying section and a third conveying section arranged inside the mounting base. The driving device comprises a pair of screws, motors arranged at the ends of the screws, a slider in threaded connection with the screws, and a pair of connecting rods hinged to the upper end of the slider. The connecting rods are arranged along a vertical plane, and the upper ends of the connecting rods are hinged to a cross bar below the second conveying section. The device has the advantage that the inclination angle of the second conveying section and the height of the third conveying section are changed by adjusting the inclination angle of the connecting rods, the inclination angle of the connecting rods can be
