  • Paper scrap pushing structure of paper shredder
    Patent number: 10875029
    Abstract: A paper scrap pushing structure of a paper shredder, including a rotating shaft, a paper pushing rod, and connecting rods, in which the rotating shaft is arranged under a paper outlet, and is in linkage with a paper shredder cutter shaft through a synchronous transmission device. The paper pushing rod is located on one side of the rotating shaft, arranged in the length direction of the rotating shaft in parallel and connected with the rotating shaft through the connecting rods. The distance from the paper pushing rod to the rotating shaft is smaller than the distance from the lowest portion of the paper shredder cutter shaft to the rotating shaft. When rotating, the rotating shaft drives the paper pushing rod to move in a circumferential direction through the connecting rods, removing paper scraps at the top of a paper scrap pile in a shredded paper waste bin.
