Torsion spring and a fastener driving tool with the same
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.
Cartridge
A cartridge includes a staple support part provided on a front end face. The staple support part includes an inclined surface protruding obliquely from the front end face in a striking direction, and is configured to support a crown portion of the staple with the inclined surface and a pair of leg portions of the staple with side edge portions of the inclined surface. The side edge portion has: a connection portion continuing to the inclined surface and extending from the inclined surface in an opposite direction to a feeding direction of the staple, by a first length; and a leg portion contact portion extending with being folded from a tip end portion of the connection portion in the feeding direction by at least the first length, and configured to support corresponding one of the pair of leg portions from an inner side thereof.
BINDING MACHINE
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.
ELECTRIC STAPLER
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.
Electric striking device
An electric striking device is provided, including a main body and a striking unit. The main body includes an interior space and an outlet opening; the striking unit is disposed in the interior space, the striking unit includes an electromagnetic device, a driving member, a steering mechanism and an impacting member, the electromagnetic device drives the driving member to move along a direction perpendicular to an open direction of the outlet opening and further drive the impacting member to move along the open direction of the outlet opening.
Staple gun with self-centering mechanism
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.
DIRECTIONAL CLINCHING TOOL AND NAILS
A clinch nailer tool system. The system includes a clinch nailer tool body, coil magazine disposed in a bottom of the clinch nailer tool body and configured to hold a coil of nails, clinch arm pivotally connected to the clinch nailer tool body at a proximal end of the clinch arm, clinch nailer tool nose disposed in a front portion of the clinch nailer tool body, wherein the clinch nailer tool nose includes an opening in a lower portion thereof for receiving a nail from the coil magazine; and clinch plate disposed on a distal end of the clinch arm, wherein the clinch plate is configured to bend a nail from the clinch nailer tool nose.
SOLENOID-POWERED STAPLER
A desktop stapler includes a base portion and a lever assembly pivotally coupled to the base portion at a pivot point. A gap is defined between the base portion and a distal end of the lever assembly opposite the pivot point. A biasing member is coupled to the lever assembly and biases the lever assembly away from the base portion. A first solenoid is operable to move the lever assembly relative to the base portion to decrease the gap. A second solenoid is operable to drive a staple from the lever assembly. A controller is programmed to sequentially actuate the first solenoid and the second solenoid.
SOLENOID-POWERED STAPLER
A desktop stapler includes a base portion. A lever is pivotally coupled to the base portion at a pivot point. A gap is defined between the base portion and a distal end of the lever opposite the pivot point. A biasing member is coupled to the lever and biases the lever away from the base portion. A solenoid is operable with a first actuation to move the lever relative to the base portion to decrease the gap and with a second actuation to drive a staple from the lever. A controller is programmed to sequentially initiate the first actuation and the second actuation.
Clinch staple mechanism
A clinch staple mechanism including a pivoting base configured to be pivotally connected to a pneumatic stapling tool. The pneumatic stapling tool is configured to dispense staples each staple having a crown and a pair of staple legs, wherein the crown is disposed in a crown direction. The clinch staple mechanism further includes a clinch arm pivotally connected to the pivoting base at a proximal end of the clinch arm; and a clinch block disposed on a distal end of the clinch arm, wherein the clinch block is configured to bend the staple legs in a direction perpendicular to the crown direction.
