Abstract
A buffering device of the invention includes a motor and a drive cutter shaft driven by the motor. Mounted on the drive cutter shaft are a drive cutter gear, a buffering disc, and a buffering gear. The buffering disc contains a cylindrical portion. A shifting block is extended from the cylindrical portion. A receiving hole is defined in the buffering gear. Plural recesses are extended from the circumferential inner wall. The cylindrical portion is inserted into the circumferential inner wall, while the shifting blocks are placed into recesses. A circumferential gap is defined between the shifting block and a recess. By this way, the gear components or motor are protected from being damaged due to overload, hence making it possible to protect the mechanical components and motor of the paper shredder.
