Abstract:
1. A shredder comprising: a shaft set driven by a motor and comprised of at least two shafts rotating in opposite directions and with cutting blade sets mounted thereon; a paper passage formed by the shafts; a sliding switch hat to switch to a reverse mode; a movable stopper provided at the exit of the paper passage; and a clearing mechanism; wherein paper enters the entry of the paper passage and is cut by the cutting blades into paper strips; the paper strips are pushed down by the rotating blades toward the exit; the paper strips accumulate at the stopper so that crinkles form on the paper strips until the accumulated paper strips force the stopper to open, thereby letting the crinkled paper strips fall; the clearing mechanism is manual and includes the sliding switch hat, a pulling bar, a transmission shaft, a lock, a stopper, a restoring switch, a pulling spring, and a torsional spring; when the sliding switch hat switches to the reverse mode, the sliding switch hat unlocks and moves the stopper to open the exit also causing the restoring switch to become active, and when the reverse mode is switched off, the restoring switch is used to close the exit.
