Claims

[Scope of utility model registration request]

A motor as a power source, a gear for power transmission and deceleration, a storage battery for supplying energy to the motor, and a compression system for storing rotational kinetic energy of the motor as elastic energy and using this energy to drive staples. A spring, a spring holder for holding a compression spring, and a drive bit for driving a staple, the drive bit being in contact with a protrusion provided on the spring and being high in the compression direction of the compression spring. The gear is characterized in that an inclined surface whose height increases in accordance with the rotation of the gear and a discontinuous portion whose height decreases from the maximum height to the bottom of the inclined surface are formed on the end face of the gear.
