Air-sac delay drive-hanging device of paper shredder

摘要

Disclosed is an air-sac delay drive-hanging device of a paper shredder that is mounted to a stand and arranged at an inner lower side of a paper entry formed on an upper lid of the paper shredder, the delay drive-hanging device including: a micro-switch, a rotating actuator, a press plate and an air-sac assembly, wherein the rotating actuator is supported by a shaft base by means of a biasing shaft, the press plate has a first end engaging with a leaf spring of the micro-switch and a second engaging with a coupling neck at a closed end of the air-sac, such that the first end would activate the leaf spring to turn on the micro-switch and the second end would exert a force inwards to compress the air-sac for rapidly discharging air within the air-sac when the press plate is activated by the rotating actuator, and that time required for the air-sac to recover to a fully inflated state would be extended because air is slowly drawn into the air-sac so as to delay the timing for the leaf spring to disengage from the micro-switch to facilitate in discharging paper shreds jammed between blade wheel shafts by means of continuous driving of the motor of the paper shredder.
