An energy storage tool includes a handle selectively linked to a power spring to deflect and store energy in the spring. The handle is decoupled from a link to the power spring by decoupling members in a release action. A peak release force results during the de-linking that is additive to a spring deflection force. An added motion bar adds leverage to the handle during the decoupling release action to reduce the peak release force.

A nail guiding device of a nailer includes a guiding portion for guiding the nails along a straight path. The nailer has a reception recess with which a guiding member is pivotably connected. A guiding plate includes two grooves defined along two sides thereof. The strike plate and nails are slidably moved along the guiding plate between the two grooves. The guiding plate has first and second slots. The guiding member has a pivot pivotably inserted in the reception recess, a first guiding portion, a first rail, a second rail parallel to the first rail and a second guiding portion. The guiding member has a resilient arm connected thereto which contacts an inside of the body of the nailer. The first and second rails swing through the first and second slots so as to guide the nails to be ejected along a straight path.

A safety device for tackers includes a safety slide slidably connected to the outlet of the tacker and the safety slide has a stop protruding from the inside thereof. The rod has one end contacts the stop and the other end of the rod has a plastic tip connected thereto. An ignition spring is connected between the plastic tip and a safety switch. A recovery spring is connected to another position of the rod to position the rod. The safety slide is slidably connected to grooves of the tacker. When the safety slide contacts against an object to be stapled, the rod is pushed by the stop and activates the ignition spring to activate the safety switch so as to reduce the impact of the rod and the safety switch.

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 nail gun of the present invention includes an adjusting portion which has elasticity. The elasticity of the adjusting portion is able to offset a thrust force of a nail pusher pushed by a magazine, so that a nail slot receives a nail only. The nail gun ensures not to shoot two sticks of nails simultaneously. The nail squeezes one side of the adjusting portion in a firing process so that the nail gun can provide sufficient space. Thereby when the nail is thicker, it can be shot by the nail gun. The present invention need not adjust by hand anymore for shooting different thickness of nails. The nail gun can not shoot two sticks of nails simultaneously.

A carrier with a fastener depth limiter. The carrier may be used to drive fasteners of a staple type. Carriers may include a fastener holder and a fastener depth limiter securable to the holder. The holder may include an axial body with distal and proximal ends, a fastener-receiving opening in the distal end normal to the axis, and an anvil-receiving opening in which an anvil repeatedly strikes a fastener held by the holder as the holder retracts during fastener driving. The fastener depth limiter may be a collar and the collar may be axially adjustable along the holder to enable user selection of the depth limitation. A workpiece-contacting distal end of a collar-type depth limiter may be spaced axially outward from the distal end of the holder a distance approximately the same as a thickness dimension of the fastener, which may be the thickness dimension of the crown of a staple-type fastener. The carrier enables consistent driving of each and every fastener relative to a cable or other workpiece thereby providing securement without damage that could be caused by excessive contact with the crown.
