Abstract
A fastener driving tool includes a striking member mounted in a housing for reciprocal movement relative to a fastener striking opening, a leaf spring engaging with the striking member at an end, and having a flexible section anchored by an anchoring unit, and a press handle pivotably connected with the anchoring unit, and having an elongated guide slot in which a pivot axle is movably engaged. The press handle is pivotable from a ready position, where the anchoring unit anchors the flexible section, through an intermediate position, where the anchoring unit is moved upwardly and rearwardly to cause resilient deflection of the leaf spring and load the leaf spring with an accumulated biasing energy, to a striking position, where the anchoring unit abuts against and is counteracted upon the pivot axle or a stop peg to be disengaged from the leaf spring so as to release the biasing energy.
