A stapler including a moveable strike plate and accessibility features is described. A slidable strike plate is moveable from a first staple forming position to a second staple forming position to form different staple shapes. The slidable strike plate is moved relative to the anvil of the stapler with a single hand to change positions. A rotatable strike plate is turned with a single hand to move between staple forming positions by rotating an outer dial of the rotatable strike plate relative to the anvil of the stapler. The stapler includes an indicator window that shows if the stapler is empty or running low on staples and a quick release staple loading magazine that is operable using a single hand.

A magazine for use with a fastening tool. The magazine can have a pusher assembly that can be retracted into a recess in the magazine to facilitate loading and reloading of fasteners. The pusher assembly can have a pusher assembly knob which can be reversibly latched to a detent to maintain the pusher assembly in a retracted state. The fastening tool can use a magazine which can be reloaded by a method which has a step of reversibly retracting the pusher assembly into the retracted state to allow for feeding one or more fasteners to the magazine.

A staple gun is adapted for driving out a frontmost staple of a staple strip and a frontmost press piece of a press piece strip simultaneously. The staple gun includes a casing unit adapted for receiving the staple strip and the press piece strip, a striker unit adapted for striking the frontmost staple and the frontmost press piece out of the casing unit through an exit opening, and a loading unit including a staple holder, a press piece pusher that is adapted to abut against a rear end of the press piece strip, and a press piece spring that is connected between the press piece pusher and the staple holder for maintaining contact between the press piece strip and a front portion of the casing unit.

A staple insertion device includes a staple drive chamber, staple reservoir, staple feed mechanism, and staple drive member. The staple drive chamber is formed between a backing plate and a jam plate removably attached to the backing plate. The staple reservoir is configured to receive and hold a plurality of staples and extends from the backing plate to a staple reservoir terminal plate. The staple feed mechanism is operatively connected to the staple reservoir and is configured to feed the plurality of staples from the staple reservoir into the staple drive chamber through the backing plate. The staple drive member is configured to advance downwardly through the staple drive chamber so as to drive a staple out of the staple drive chamber.

A reload assembly includes a shell housing, a knife carrier, a lockout component, and a hook component. The lockout component is supported on an inner wall of the knife carrier and has a body formed of a resilient material that defines a window. The hook component is supported on the inner housing portion of the shell housing and includes a body having a hook that is received within the window of the lockout component when the knife carrier is in its retracted position after the reload assembly has been fired to obstruct readvancement of the knife carrier.

A hammer tacker is provided, including a grip portion and a body portion; a magazine, including a rail, at least partially received in the housing, being movable relative to the housing between a stapling position and a staple-installing position, including an outlet disposed at a front end of the body portion; a biasing mechanism, including a push member movably mounted to the rail and a constant force spring which is rollable, the constant force spring being positionally attached to the rail through a connection portion and located at a front end of the magazine, and the constant force spring being attached to an inner face of the push member, the push member being movable to be correspondingly above or beyond the connection portion; a striking mechanism, mounted to the body portion and configured to strike at least one staple installed in the magazine.

A fastening tool having a nail stop which positions a nail for driving and is made at least in part of a contact material which can be investment cast and/or hardened. The contact material can resist wear from the action of driving the nail and the movement of a driver blade. The nail stop can be configured to align nails fed from a magazine and can be offset from the longitudinal centerline of the fastening tool. The nail stop can have a head contact length which is 0.5% to 95% of the length of the nail to be driven. The nail stop is used in methods for positioning a nail for driving.
