Hand-operated coil stapler

A hand-operated coil stapler, comprising:

• a main body including a case, in which an operation room is defined;
• and a linkage system being arranged in the operation room and pivotally connected to the case;
• a staple driving mechanism being assembled to a head portion at a front end of the main body, and including a pressing member and a complex staple driver;
• the pressing member being movably assembled to an outer side of the case to engage with the linkage system;
• and the complex staple driver also being engaged with the linkage system and including a driving plate and a bending plate;
• a pusher and magazine assembly being connected to a bottom of the main body, so that the pusher and magazine assembly and the main body together define a staple room in between them;
• the pusher and magazine assembly including a magazine and a movable pusher mechanism mounted in the magazine;
• and the pusher mechanism including a push rod, a push plate fixedly connected to a front end of the push rod, and a staple-pushing spring fitted around another end of the push rod;
• and
• a coil staple unit including a plurality of bar-shaped staples, which are parallelly arranged and continuously connected to form a web for winding into a coil;
• and the coil staple unit being mounted in the staple room with a front end thereof located below the complex staple driver;
• wherein when the main body is downward pushed relative to the pressing member, the linkage system brings the complex staple driver to move downward to thereby bend a first one of the bar-shaped staples at the front end of the coil staple unit and drive the bent staple downward at the same time;
• meanwhile, the downward moved complex staple driver comes into contact with the push rod, forcing the same backward and thereby compressing the staple-pushing spring;
• and when the main body is released, the complex staple driver is moved upward to separate from the push rod, and the staple-pushing spring is released from the compressed state to thereby elastically push the push plate and the push rod forward, which in turn move a subsequent staple on the coil staple unit to the position immediately below the complex staple driver for use in a next stapling operation.
