A fastener driving tool includes a housing, a drive track within the housing, a magazine connected to the housing and configured to hold a supply of fasteners and to provide a leading fastener to the drive track, a driver configured to move downward in the drive track and drive the leading fastener into a workpiece during a drive stroke, a mount connected to the driver, and a clincher operatively connected to the housing and to the mount. The clincher is configured to engage the leading fastener during the drive stroke and move into a clinching position at the end of the drive stroke to clinch the fastener to the workpiece. A motor is configured to rotate a crank arm, and a connecting rod is pivotably connected to the mount at one end portion thereof and pivotably connected to the crank arm at an opposite end portion thereof.

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 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.

Various embodiments of the present disclosure provide a battery-powered stapling tool. In one embodiment, the stapling tool includes a drive wheel, a cam drivable by the drive wheel in a first rotational direction from a first position to a second position and back to the first position to carry out a staple-driving process, a motor operably connected to the drive wheel to drive the drive wheel, a lifting element defining a slide in which the cam is received, and an ejector connected to the lifting element and drivable by the lifting element between an ejector home position and an ejector ejection position. The slide has first and second slide segments that are transverse to one another. The lifting element is movable between a lifting-element home position and a lifting-element ejection position.

A staple cartridge for use with a stapling device that has an actuator that is selectively actuatable in an axial direction and an anvil portion that is selectively movable between open and closed positions is disclosed. Various embodiments of the present invention include a cartridge body that movably supports first and second staple drivers. The staple drivers each support a staple thereon and serve to drive the staples into forming contact with the anvil upon actuation by the actuator. The various embodiments of the present invention enable the final formed heights of the staples to be varied without the need to use different sizes of staples.

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.

An electric stapler is configured to perform binding processing including a plurality of processes. The electric stapler includes: a binding unit configured to execute the binding processing for a sheet bundle; a motor configured to drive the binding unit; and a control unit configured to control the motor. The control unit is configured to control the motor; thereby adjusting processing times of the processes so that a binding processing time after the binding processing by the binding unit starts until the binding processing is completed falls within a predetermined range.

A fastener driving tool includes a magazine unit, a handle, a striking plate, an energy restoring member and a wire bending spring disposed to a housing unit. The housing unit includes an inner housing assembly made from a plastic material, and an outer housing assembly made from a metal material and covering the inner housing assembly. The wire bending spring is biased for storing a striking energy for the striking plate, and includes an extending section and a backwinding section. The extending section has first and second ends. The backwinding section is connected with the second end, and extends and bends toward the first end to terminate at a terminal end portion. The ratio of a height to a width ranges from 1:1 to 1:1.6.

A fastener delivery tool may comprise a sheath assembly having at least one position retention member proximate a distal end of the sheath assembly, and a handle assembly coupled to a proximal end of the sheath assembly, the handle assembly comprising a housing, a trigger handle, and an insert connector. An external force applied to the trigger handle may cause displacement of the trigger handle relative to a rest position, and displacement of the trigger handle from the rest position within a first displacement range may impart a first amount of force on the insert connector relative to the applied external force and displacement of the trigger handle from the rest position within a second displacement range may impart a second amount of force on the insert connector relative to the applied external force, with the first amount of force being greater than the second amount of force.
