A nail machine with effort-saving mechanism is provided, including: a shell body; an operating mechanism, disposed on the shell body and including a pressing lever, a driving rod and a linkage, the operating mechanism provided for being operated to move between a first position and a second position; an actuating member, two ends thereof having a sliding portion and an engaging portion respectively; a striking force accumulating mechanism, including a striking board and a force accumulating member, the striking board being movable between an initial position and a releasing position; wherein when the operating mechanism moves toward the second position, the engaging portion is engaged with the striking board, and the striking board moves toward the releasing position; when the operating mechanism is in the second position, the engaging portion is detached from the striking board, and the striking board moves toward the initial position.

A wire installation apparatus is provided. The wire installation apparatus includes a body through which a peg passes, a reel installed in the body to surround a wire, a wire guide member guiding the wire, and an external force transfer member transferring an external force, applied from the outside, to the peg so that the peg is driven into a ground. The wire is installed by the peg driven into the ground.

A fastener driver apparatus suitable for guiding and driving electrical staples into timber or on any other suitable mounting surface is presented. The fastener driver contains a driver body, a driver rod, and a fastener guide. The driver body contains a first driver channel and a mounting end. The mounting end is positioned adjacent to the driver body. The first driver channel traverses through the driver body and the mounting end. The driver rod is slidably connected to the driver body. The fastener guide is connected adjacent to the mounting end.

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.

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 hammer tacker includes a body having a nail track, an operation assembly and a strike plate. The operation assembly drives the strike plate to eject the nails. The operation assembly includes an operation unit which has a passive end to drive a resilient member located above the nail track. The resilient member provides the operation assembly a force to return to its initial position. The resilient member has one end mounted to a positioning member which has an insertion inserted into one end of the resilient member, and a flange extends outward from one end of the insertion. The flange has an end face contacts the passive end of the operation unit so as to ensure the resilient member to be operated in a horizontal direction.
