A hammer tacker includes an outer housing comprising a handle portion and a head portion, the outer housing formed from a fiber reinforced polymer material. The hammer tacker also includes an elongated staple holder carried at least partially within the outer housing, the elongated staple holder being slideable between a use position and a refill position. The outer housing having the fiber reinforced polymer material defines a channel extending through the handle portion and into the head portion, the channel configured to receive the staple holder. The staple holder is slidable along the channel of the outer housing between the use position and the refill position. The hammer tacker further includes a staple driver assembly operable to drive a staple from the staple holder into a workpiece.

A positioning structure of stapler handle includes a buckle assembly and a buckle member. The buckle assembly includes a first coupling portion and a pushing unit connected together. The buckle member includes a first second coupling portion and a pushed unit connected together. The first coupling portion is adapted for being coupled with the second coupling portion. The pushed unit is located at the movement path of the buckle assembly.

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.

The stapler includes a main body, a trigger, a striking mechanism, and a stopping plate. The main body has an outlet at a first end portion. The trigger is pivotally connected to the main body with an end, and the other end extends toward the first end portion for being pressed toward the main body. The striking mechanism includes a striker at the first end portion and a releasing unit for releasing the striker. The trigger switches the releasing unit between a release mode and an accumulating mode so that the striker can move toward the outlet. The striker has a concave face facing the outlet for striking a staple unit. The stopping plate is disposed on the first end portion and is for the staple unit to abut against horizontally. The stopping plate has at least one recess at an end thereof facing the outlet.

A staple gun is provided, including: a main body, including a bottom side, and a staple outlet and a notch disposed on the bottom side; a staple magazine, being withdrawably received within the main body, including a track portion and an abutting portion out of the track portion; a lock mechanism, being located at the bottom side, including a pressed member disposed on the main body and located within the notch, the pressed member having a blocking portion movable between a blocking position and a releasing position; wherein when the blocking portion is in the blocking position, the blocking portion is blockably connected with the abutting portion and the staple magazine is non-withdrawable from the main body; when the blocking portion is in the releasing position, the blocking portion is unlocked by the abutting portion and the staple magazine is withdrawable from the main body.

A fastener delivery tool may comprise a sheath assembly having at least one position retention member proximate a distal end of the sheath assembly, and a handle assembly coupled to a proximal end of the sheath assembly, the handle assembly comprising a housing, a trigger handle, and an insert connector. An external force applied to the trigger handle may cause displacement of the trigger handle relative to a rest position, and displacement of the trigger handle from the rest position within a first displacement range may impart a first amount of force on the insert connector relative to the applied external force and displacement of the trigger handle from the rest position within a second displacement range may impart a second amount of force on the insert connector relative to the applied external force, with the first amount of force being greater than the second amount of force.

A novel quick fastening device comprises a base, an energy storage medium, an impact unit and a driving mechanism; the driving mechanism includes an annular gear, a driving shaft, a crank, a planet gear; the planet gear is placed in the annular gear and engaging with the annular gear, so that it can implement revolution against annular gear, the planet gear implements rotation at the upper end of crank; a clamp shaft for connecting the impact unit is located in the upper end of the connecting rod, the lower end of driving shaft is connected to the rotating energy release unit; the annular gear-planet gear structure to implement the conversion of rotary motion into reciprocating motion, the kinematic trajectory of clamp shaft on the connecting rod approximates to a straight line, so as to reduce the kinetic friction force of load to the maximum extent to avoid wear.
