The invention discloses a waste landing point-variable waste discharge mechanism. The waste landing point-variable waste discharge mechanism comprises stand columns on a punching machine; an inclineddischarge groove plate is arranged between the stand columns; a rotating shaft is hinged between the stand columns; support rods are fixedly inserted in the two sides of the rotating shaft; one ends of the support rods butt against the bottom surface of the discharge groove plate; a support shaft is inserted between the support rods; beating rods are inserted in the two sides of the support shaft,and are provided with arc beating plates; pressure springs are fixed on the beating rods on one sides above the beating plates; one end of the support shaft penetrates through the support rods, and is inserted with a torsion spring; the two ends of the torsion spring are respectively fixed on the side walls of the support rods and the support shaft; a limiting rod is inserted in the end side wallof the support shaft, and cooperates with a spline of the support shaft; limiting keys are molded on the side wall of the limiting rod; limiting grooves are molded on the side walls of the support rods; and the limiting keys are inserted in the limiting grooves. The waste landing point-variable waste discharge mechanism is variable in waste landing point, is suitable for loading wastes in large waste frames, and meanwhile, can realize smooth discharge of wastes.
