paper scraps generated after waste paper is processed by a motor paper shredder (4) are sequentially guided into a scrap collecting barrel (56) from a scrap inlet (55) through a scrap guiding U-shaped chute (52) and a scrap guiding bent pipe (54), a rocker (511) is swung anticlockwise at the moment to enable a driving belt pulley (515) to rotate, a driving belt (516) is arranged between the driving belt pulley (515) and a driven belt pulley (519), the driving belt (516) rotates anticlockwise at the moment, the driving belt (516) is matched with a driving wheel (538), the driving wheel (538) rotates anticlockwise, a connecting circular shaft (539) is embedded and fixed on a notch of the driving wheel (538), the other end of the connecting circular shaft is fixed on a gear (518-f), and the gear (518-f) rotates anticlockwise and moves downwards along a rack (518-g);

the scrap pressing plate (534) is driven to slide downwards along the first longitudinal sliding rail (57) and the second longitudinal sliding rail (517), scraps in the scrap collecting barrel (56) are extruded by the scrap pressing plate (534), so that the quantity of the scraps stored in the scrap collecting barrel (56) is increased, a reset tension spring (518-a) is arranged between the first sliding block (518-e) and the spring limiting joint (518-b), after the scrap pressing plate (534) works downwards, the first sliding block (518-e) of the rocker (511) is loosened to realize upward automatic reset due to the reset elastic force of the spring, and after a certain quantity of the scraps are stored, the movable bottom cover (58) is opened from the bottom of the scrap collecting barrel (56);

make the wastepaper fall into the garbage bin along activity bottom (58) incline direction, and then avoided album problem that wastepaper can waft to ground after bits bucket (56) takes out, installed first chamfer scraper blade (531) and second chamfer scraper blade (5310) on pressing bits board (534), effort can strike off the wastepaper that adheres at first longitudinal slide rail (57) and second longitudinal slide rail (517) when utilizing to press bits board (534) vertical activity from top to bottom, improves the slip efficiency of pressing bits board (534).
