Abstract

A labor-saving stapler of the present invention includes a base, a press arm, a transmission arm, a connection arm, a magazine, a staple pusher, a moving mechanism, a buckling mechanism and a switching mechanism. The magazine is slidably disposed between the connection arm and the base. The moving means moves the magazine outwardly when the switching mechanism is activated. As such, the magazine can be opened by operating the switching mechanism. When the switching mechanism includes a button or the same, users can open the magazine easily with only one hand.
