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.

A power transmission mechanism for use in an electrically operated stapler, comprising: a casing; an electrical power means coupled to a control switch disposed within the casing; a pair of speed reducing gears in engagement with each other; a driven gear in engagement with one of said speed reducing gear; a flywheel horizontally disposed and mounted on the top end of the axle of said driven gear, with a vertical pin projected from the top surface thereof and located near the peripheral edge thereof; a ram means having an oblong piece extending from the front end thereof serving as a hitting means, and the underside of said ram means being provided with a vertical wall; a trigger means in association with a bias spring for permitting the same to be retractably operated; a link in operative association with said trigger means by pivotably fixing the link to a cylindrical projection on the trigger means, and a coil spring being engaged with both said link and said trigger means so that the link can be resiliently operated in response to the actuation of said trigger means.
