Paper scrap pushing structure of paper shredder

A paper scrap pushing structure of a paper shredder having two opposing sides, comprising:

• a paper pushing unit, including
• a common rotating shaft,
• a paper pushing rod, arranged in the length direction of the common rotating shaft in parallel, and
• two connecting rods, connecting the common rotating shaft to the paper pushing rod;
• wherein the two connecting rods are the left connecting rod and the right connecting rod respectively, with the left connecting rod and the right connecting rod being located at respective ends of the paper pushing rod and the common rotating shaft,
• wherein the common rotating shaft is arranged under a paper outlet of the paper shredder and is in linkage with a paper shredder cutter shaft through a synchronous transmission device,
• wherein the distance from the paper pushing rod to the common rotating shaft is smaller than the distance from the lowest portion of the paper shredder cutter shaft to the common rotating shaft,
• wherein the left connecting rod and the right connecting rod are each a telescopic structure, and springs are arranged proximate to respective ends of the common rotating shaft on the left connecting rod and the right connecting rod and
• wherein when the common rotating shaft rotates, the common rotating shaft drives the paper pushing rod to move in the circumferential direction through the connecting rods, removing paper scraps at the top of a paper scrap pile in a shredded paper waste bin and two inverted U-shaped guide grooves oppositely arranged on inner walls of side plates on the two opposing sides of the paper shredder, wherein the paper pushing rod enters the inverted U-shaped guide grooves when rotating around the common rotating shaft in the circumferential direction and is compressed to be prevented from colliding with the paper shredder cutter shaft above.
