A labor-saving stapler is provided, including: a housing, having a nail outlet; a striker, disposed within the housing and movable between a preset position away from the nail outlet and a nailing position near the nail outlet; an energy-accumulating mechanism, including a connection portion connected to the housing and a connection end cooperating with the striker; an operable mechanism, movably connected to the housing and having a depression portion abutable against the energy-accumulating mechanism; a limitation mechanism, connected to the housing, the striker being positionably restricted by the limitation mechanism; wherein when the striker is in a preset position and positionably restricted by the limitation mechanism, the energy-accumulating mechanism is depressible by the depression portion to be in a energy-accumulating state, and when the striker is free of restriction by the limitation mechanism, the energy-accumulating mechanism actuates the striker to move toward the nailing position.

A spring energized fastening tool with compact, rigid, low friction working elements is disclosed. A torsion power spring includes forward extending arms with the arms pressing each other proximate a front distal end of the spring. A cantilevered lever links to a handle and engages the spring adjacent to the striker. A bottom loading staple track unlatches and opens through a simple pulling-out action. Structures are provided to enable fitment with a formed sheet metal handle and housing. The fastening tool is particularly simple to assemble, powerful, and of low operating effort.

A wire stapler for tacking an elongate element at an elevated location is disclosed herein. The element may be one of a cable, a rope light, decorations, and the like. The wire stapler comprises a handle. An elongate hammer is coupled to the handle and extends therefrom. An elongate sleeve is configured to receive the elongate hammer therewithin. A sleeve end is configured for coupling at an operative end of the sleeve, wherein the sleeve end includes a staple receiving pocket configured thereon for receiving a staple therein, wherein the hammer is configured for reciprocation within the sleeve and collision with the staple for tacking the element accommodated between the staple at the elevated location.

A stapler includes a staple ejection unit configured to eject a staple and cause the staple to penetrate an object, a stitching unit configured to bend staple legs of the staple penetrating the object, and a driving unit configured to move the staple ejection unit in a direction close to and away from the stitching unit along a first direction indicated by an arrow. The staple ejection unit has an ejection surface from which the staple is ejected, and a base surface located between the ejection surface and the driving unit, the stitching unit has a bending surface facing the ejection surface and configured to bend the staple legs, and the ejection surface protrudes with respect to the base surface in the direction of the bending surface along the first direction.
