A device includes a first member having a first surface, and a second member having a second surface that is partially or wholly in contact with the first surface. The first member and the second member are configured to operate relatively. The first member has a flow path of a lubricant that has an opening provided in the first surface.

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 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 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.

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.

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.

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.
