A connection fastener in which a plurality of fasteners for a driving tool are connected includes a connection band which detachably connects sleeves holding the fasteners one by one. A gap is formed between the sleeve and the fastener so as to face a toe side of the fastener.

Connection fastener

A striking tool includes: a driver which is provided to be slidable toward an ejecting port provided in a tip end of the striking tool so as to strike out a fastener from the ejecting port; a plunger to which the driver is coupled; a plunger urging member which is configured to urge the plunger toward the ejecting port: and a drive mechanism which is configured to move the plunger to accumulate urging force in the plunger urging member. A standby position of the plunger before striking out the fastener can be switched between a usual standby position and a standby position for maintenance closer to the ejecting port than the usual standby position.

Striking tool

An impact tool can be operated by generating an impact using an internal mechanism. The impact tool includes a control unit and sensors. The control unit controls the internal mechanism. The sensors output a signal for operating the internal mechanism or a signal for preparing the operation of the internal mechanism, to the control unit. Until a predetermined condition is established after the internal mechanism is operated, the control unit does not accept the input of the sensors.

A fuel container holding structure for detachably holding a fuel containerincluding a nozzlein its front end portion is provided with a front end holding portionfor holding the front end portion of the fuel containerand a rear end holding portionfor holding a rear end portion of the fuel container. The front end holding portionincludes a connecting portionto which the nozzleis connected and a buffer mechanismdisposed between the connecting portionand fuel container. The fuel containeris supported by the buffer mechanism

Fuel container holding structure

In a gas combustion type striking machine, a combustion chamber is opened and closed by moving a movable sleeve in a vertical direction. A safety lever is attached to a trigger, and a switch is switched by being pressed by a switch lever arranged to be engageable with the safety lever. A hold member which is engageable with the movable sleeve is rotatably connected to the trigger. A shaft supporting a base end of the hold member positions between a shaft supporting the switch lever and a cylinder in a right-left direction which is perpendicular to the vertical direction.

Gas combustion type striking machine

A gas combustion type driving tool is provided with a combustion portion; a fuel container for containing a fuel; an electromagnetic valve device for injecting the fuel into the combustion portion; and a grip portion. A distance from the fuel container to the combustion portion is set substantially equal to or less than a distance from the electromagnetic valve device () to the combustion portion.

A part clamp is temporarily held in a short cylindrical portion provided on a contact arm of a nailing machine and is nailed to a building body or the like by the nailing machine. The part clamp is provided with a base portion having a through hole at its center for inserting a nail therethrough, and an engaging portions for engaging with the short cylindrical portion. When the part clamp is pushed in the axial direction of an injection port of the nailing machine, the part clamp is temporarily held in the short cylindrical portion. The load to push the part clamp to engage with the short cylindrical portion is lower than the load to push the contact arm to slide along the injection port.

Part clamp and nailing machine

An injection nozzlefor injecting a combustible gas into an annular combustion chamberformed above a driving cylinderis formed so as to face the interior of the combustion chamber, in which a rotary fanfor mixing a combustion gas supplied into the combustion chamberand air is provided. A vortex generatoris formed in an upstream side of the injection nozzlein an air flow formed in the combustion chamberby the rotary fan. Vortexes are generated near the injection nozzlein the combustion chamberby the vortex generator, so that the mixing of the combustion gas and air is promoted.

Gas combustion-type impact device

A front end of a ball screw shaft driven by a motor is connected with a binding line clamp apparatus () including three clamp plates (). The left and right clamp plates () are constituted to be brought into elastic contact with the center clamp plate () and close the left and right clamp plates by operation of cams () when a sleeve is moved rearward. In a state of opening the clamp plates, a binding line is fed out to an upper side by passing through an interval between the right clamp plate () and the center clamp plate (), formed in a loop shape and moved into an interval between the left clamp plate () and the center clamp plate (). When the sleeve is moved rearward by driving to rotate a ball screw shaft, the left and right clamp plates are closed to grasp a front end and a rear end of the binding line loop and thereafter, the binding line clamp apparatus is rotated to twist the binding line to bind a reinforcing bar.

Reinforcing steel bar typing machine

A final gear () and a ball screw shaft () of a rotation drive system of a binding line twist mechanism are connected by a spline and a shaft portion of a center clamp plate () of a binding line clamp apparatus () is connected to a front end of the ball screw shaft (). A shift mechanism for moving the ball screw shaft () and the binding line clamp apparatus () in a front and rear direction by a slide motor () is provided. A wire (W) is wound around a reinforcing bar (S) by a binding line feed mechanism, the wire is grasped by a front end portion of the binding line clamp apparatus () and thereafter, a shift mechanism applies a tension to a loop of the wire by moving rearward the binding line clamp apparatus (). The binding line clamp apparatus () is rotated by a twist motor () and the shift mechanism twists up the wire by moving forward the binding line clamp apparatus (). Since the wire is applied with the tension and twisted, a reinforcing bar binding strength of the wire loop is stabilized.

Reinforcing steel bar tying machine

A reverse rotational number of a binding wire feed mechanism is set such that a binding wire is completely pulled back regardless of a boldness or flexibility of the binding wire, a diameter of a reinforcing bar or the like. A driven gearhaving a V groove of the binding wire feed mechanism is brought into elastic contact with a main drive gearhaving a V groove by a spring and the binding wire is fed by pinching the binding wire by the main drive gearhaving the V groove and the driven gearhaving the V groove. After feeding out the binding wire to form a loop around the reinforcing bar and clamping a front end of the binding wire by a twist mechanism, the binding wire feed mechanism is rotated reversely and the binding wire is pulled back to be wound around the reinforcing bar. After stopping the binding wire, the main drive gearhaving the V groove and the driven gearhaving the V groove are slipped relative to the binding wire to rotate idly and continue to rotate reversely until a predetermined rotational number.
