Abstract: A hand-held cutter with automatic blade changer which has a casing, short blades each with an aperture, a pushbutton and a plug, and the casing is composed of an outer casing, a fixed blade holder and a retractable blade holder; and it further has a blade changer which is divided into a blade unloading chamber and a blade loading chamber. The present invention has the advantages of being simple in construction and convenient to use, and allowing the users to change and dispose of the blades without touching them, thereby effectively protecting personal safety.

Abstract: A stapler that requires exertion of less effort comprising a body, an electric motor, a power supply, a power supply switch, a motion transmission mechanism having a gear cluster driven by the electric motor, a staple driving mechanism having a driving blade and a staple magazine driven by the motion transmission mechanism. The motion transmission mechanism comprises a rocking arm, and the rocking arm is a crank which is composed of a connecting shaft and a rocking shaft. The end of the connecting shaft connects to the top of the driving blade. The end of the rocking shaft is a gear, and the gear of the rocking arm has teeth which mesh with teeth of at least one gear of the gear cluster. The motion transmission mechanism comprises a double pole changeover switch and a micro switch.
