[0019] A connecting plate 31 is screwed and fixed on the right end of the feeder 1, and the upper groove surface of the connecting plate 31 is connected to the flip plate 3 through a rotating shaft 33. The flip plate 3 is provided with adsorption holes 35 through the upper surface, and the rear side of the flip plate 3 is connected to a vacuum tube 34.
