ABSTRACT:
The present disclosure is related to a power transmission mechanism for use in an electrically operated stapler, which includes a high speed motor driving a flywheel through a pair of speed reducing gears; on the flywheel is disposed a vertical pin which is moved in synchronism with the wheel in each cycle to hit a ram member having a spring located therebehind which can be compressed then extended to force the ram to strike a staple in a power stroke. Thus the present electric stapler is free of use of a conventional electromagnetic coil; besides, the striking force of the ram can be more stable, not influenced by the inefficiency of local power supply, because of the adoption of a rechargeable battery disposed within the casing of the present stapler.
