A cap hammer for driving a staple through a cap into a work surface. The cap hammer includes a staple magazine configured to hold a plurality of staples, a cap magazine disposed beneath the staple magazine and configured to hold a horizontal stack of caps, an internal guide body disposed at a forward end of the cap hammer, a cap driver blade disposed within the internal guide body configured to shear a cap from the stack of caps, a staple driver blade disposed within the internal guide body configured to shear a staple from the plurality of staples, and a work contact element disposed at the forward end of the cap hammer and configured to activate the cap driver blade and the staple driver blade when depressed against a work surface.

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 nailing unit comprising a nail box, a nail magazine, a nail pushing block, a tail buckle switch, a nail limiting block fit together with a nail guiding plate through slits is provided. The nail magazine includes a heat-treated guide rail assembly mounted with a nail splitting plate at the end near the nail guiding plate; the nail pushing block which is connected to a spring is formed with three nail pushing feet adapted to a first, second, and third gaps; the nail guiding plate includes two connecting wings and forms a low-lying guide plate therebetween; each angle between the guide plate and each connecting wing is respectively fixedly provided with a positioning step along the longitudinal direction.

The nailing unit fulfills efficient nailing for T nails, straight nails, and different types of code nails and U nails, and prolongs the service life of the nail gun.

A staple gun and a method of using the same. A stapling mechanism in the housing is activated to deliver a staple through an aperture in a housing wall and drive the staple into a surface around a stack of one or more electric cables. The gun includes a reciprocating cable guide for centering the gun on the stack of cables and closing a safety switch to permit the gun's trigger to be activated. A spacer extending outwardly from the housing wall rests on the upper surface of the cable stack. The spacer and a bumper that engages a hammer of the stapling mechanism provide for automatic depth adjustment when driving the staple into the surface. A reciprocating cable guard extending outwardly from the housing wall is positioned between the stack of cables and the staple to aid in preventing the staple from piercing the cable.

A fastener driver includes a housing defining a head portion and a handle portion, a drive mechanism positioned within the housing, and a firing mechanism. The firing mechanism includes a piston, a driver blade attached to the piston, a biasing member having a first end supported within the piston and a second end supported by the head portion, and a damper positioned between the firing mechanism and the head portion of the housing. The damper configured to attenuate one or more of noise or vibration from the firing mechanism as the driver blade moves from the top dead center position toward the bottom dead center position.
