A stapler includes a handle unit connected to a driver unit by a transmission shaft portion provided between a fulcrum shaft portion and a driver, and configured to move the driver unit; a camshaft provided to a clincher unit; a cam groove portion provided to the handle unit, configured to permit the camshaft to enter, and having one open end portion to enable to the camshaft to be inserted/pulled out; a guide convex portion provided to the clincher unit, and a guide concave portion provided to the handle unit and configured to restrict a movement path of the handle unit with respect to the clincher unit.

An electric stapler includes a main body, a handle, a striking assembly, and a safety mechanism between the main body and the handle. The handle is movable with respect to the main body between an original position and an unlock position. The striking assembly includes a striking mechanism for striking the staple out and a trigger switch on the handle for triggering the striking mechanism. The trigger switch has a strikable state and a locking state. When the handle is at the original position, the safety mechanism is at a locking mode to make the trigger switch at the locking state. When the handle is at the unlock position, the safety mechanism is at an unlock mode to make the trigger switch at the strikable state. An angle between the moving direction of the handle and the striking direction is smaller than 90 degrees.

The present invention provides a multifunctional stapler including a housing, a nailing portion arranged at a front end of the housing, and a toggling device, a part of which being arranged inside the housing and a part of which extending to the outside of the housing. The nailing portion comprises: a staple feeding member arranged at a front end of the bottom of the housing, a staple feeding groove arranged on the surface at one side of the staple feeding member for receiving staples, a striking member, a part of which being inserted into the staple feeding groove, the toggling device controlling the striking member to strike the staples, and an adjusting device, a part of which being arranged outside the housing, for adjusting a depth of the staple feeding groove.

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 fastener driving tool includes a housing, a striking member, an energy storing unit and a handle unit. The energy storing unit has a torsion spring which has weighted and driving legs extending from two ends of a coil. The driving leg is biased against and engaged with the weighted leg to be preloaded with a downward potential energy that urges a downward movement of the torsion spring and the striking member. The handle unit includes a handle and an anchoring member removably engaged with the striking member. When the handle is pivotally moved from a ready position to a striking position, the weighted leg is moved downwardly and the anchoring member and the striking member are moved upwardly to gradually increase a loading of the torsion spring for the striking member.

A binding machine, includes: a staple magazine unit configured to accommodate a staple having a crown portion and a pair of leg portions; a staple driver provided at a position facing the crown portion; a clincher provided at a position facing tip ends of the leg portions and movable along an extending direction of the leg portions; and a regulating portion configured to regulate a movement amount of the clincher toward the leg portions. The clincher and the staple driver are configured to sandwich the staple therebetween with a movement of the clincher along the extending direction toward the leg portions, folding the staple.

A binding machine that binds objects with a tape, the binding machine includes a staple magazine unit configured to accommodate a plurality of staples, a main handle, a clincher arm configured to approach a leading staple of the plurality of staples and a clincher configured to bend the leading staple. The clincher has, on a surface thereof, a first groove that extends in an acute angle direction with respect to an axial direction of a rotation shaft of the clincher arm and has a first groove length and a first groove width, and a second groove that extends in an acute angle direction with respect to the axial direction of the rotation shaft of the clincher arm and has a second groove length and a second groove width. The second groove is disposed offset with respect to the first groove in a width direction of the first groove.

A binding machine, includes a staple guide portion adjacent to a staple in a staple accommodating portion. A staple driver moves from below to above and pushes the staple located at the front end portion upward while pushing the crown portion of the staple. A clincher abuts against the pair of leg portions of the staple pushed out in a process of the staple driver moving upward from below so as to fold the pair of leg portions. The staple guide supports the crown portion of the staple from a side near a base end portion of the crown portion in a process of the staple being pushed out.

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.

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.
