ABSTRACT:
The present invention provides a stapler with a novel leaf spring actuation mechanism. According to the teaching of the present invention, the stapler comprises a striking plate for dispensing a staple from a staple magazine, a leaf spring engaged with the striking plate for driving the striking plate, and an actuation bar for lifting the leaf spring from a first position to a second position whereby lifting the striking plate from an initial position to a release position in which the leaf spring is released from the actuation bar to drive the striking plate towards the initial position. Preferably, a pair of lugs on the actuation bar pushes up a pair of tabs on the leaf spring when an L-shaped front end of the actuation bar moves upward along a ramp when an external force is applied to the actuation bar during the stapling operation.
