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.

A stapler is provided, including: a main body, having a front end and a rear end; a magazine, disposed in the main body having an outlet end; a striker, disposed in the main body and located between the front end and the outlet end along the longitudinal direction; a driving mechanism, connected to the striker to optionally drive the striker to strike the staple; a pressing element, located in the main body and between the striker and the outlet end along the longitudinal direction, the pressing element being movable between an original position and a pressed position, the original position being higher than the pressed position, the pressing element having a tendency to stay on the original position, when the pressing element is located on the pressed position, the pressing element presses the staples which are exposed outside the outlet end of the magazine.

A driving tool includes a head-guide surface and a pair of leg-guide grooves, both are formed in a driving passage extending in a driving direction. The head-guide surface slidably guides a head of a U-shaped driving member. Each of the pair of leg-guide grooves is recessed from the head-guide surface toward a side of a first end surface of a tool main body. Legs of the driving member enter the leg-guide grooves. The driving member is driven in an inclined posture in which the legs enter the leg-guide groove, thereby avoiding a slipping off posture in which a driver is deviated from the driving member owing to a reaction force occurred when the driving member is driven by the driver.

In one aspect, a conveyor belt fastener is provided having a rigid body made from a strip of cold-rolled or cold-drawn material such as steel. The body has an upper plate portion, a lower plate portion, and loop portions connecting the upper and lower plate portions. The upper and lower plate portions each have a variable cross-sectional thickness laterally thereacross including raised walls projecting outwardly and ribs projecting inwardly. The fastener has at least one attachment member, such as a staple, for connecting the plate portions to a conveyor belt end and the raised walls protect the staple once driven into the conveyor belt end.

The stapler includes a main body, a magazine, a striker, and a driving portion. The main body encloses a receiving space and has an opening at a lower portion of a front end thereof A longitudinal direction is defined by the front end and a rear end of the main body. The magazine is arranged in the main body to receive staples. The striker is arranged at the front end of the main body and is movable linearly above the opening of the main body. The driving portion is arranged in the main body and is connected to the striker. The driving portion drives the striker to move downward to strike a staple out. The striker has a bottom end which is recessed and has two ends and an intermediate portion between the two ends. The intermediate portion is more recessed than the two ends.

A staple gun includes a base seat having a pivot shaft and a coupling shaft, a striking member disposed movably in the base seat and having a connecting hole, an elastic member engaging the connecting hole, a driving member having a slot and a linking hole that is engaged with the elastic member, and a handle. The driving member is inclined with a lower portion thereof being disposed in front of an upper portion thereof. The handle has a cam surface, and an engaging hole retaining the pivot shaft. Pivot movement of the handle toward a pressed position deforms the elastic member resiliently and moves the handle rearwardly due to a slidable contact between the cam surface and the coupling shaft.

A powered fastener driver includes a magazine configured to receive fasteners, a pusher slidably coupled to the magazine, a nosepiece coupled to the magazine, and a workpiece contact element movable with respect to the nosepiece. The powered fastener driver further includes a lockout member pivotally coupled to the nosepiece, and a magnet exerting a magnetic force on the lockout member to bias the lockout member toward a first position. The pusher moves the lockout member to a second position where the lockout member blocks movement of the workpiece contact element when a predetermined number of fasteners remain in the magazine.
