A fastening tool using a fastener of a type which is configured such that swaging is completed while an end region of a shaft part of a bolt remains integrated with the shaft part, and more particularly, a technique that may help provide a compact device structure while facilitating output management required for swaging, in the fastening tool. The fastening tool is configured to fasten a workpiece with a bolt and a collar without breaking a shaft part of the bolt, and a control part performs swaging operation while controlling the driving current of a motor to become a specified target current value and completes the swaging operation based on rotation speed of the motor.

A tool for installing a blind fastener including a core bolt and a core nut is provided. The tool includes a driving member, a collet driven by the driving member for engaging the core bolt, and an external sleeve for holding the core nut and preventing the core nut from rotating during installation of the blind fastener. The external sleeve is movable between a first position in which the external sleeve is driven by the collet to rotate with the collet and a second position in which the external sleeve is stationary despite rotating action of the collet.

A blind fastener tool with pulling fingers is provided. One embodiment is a tool for installing a blind fastener in a hole. The tool includes stationary fingers having tips protruding from a front end of the housing to contact a rim of a sleeve of the blind fastener. The tool also includes pulling fingers in the housing arranged longitudinally in spaces between the stationary fingers. Ends of the pulling fingers proximate to the front end are configured to radially expand to receive a drive element of the blind fastener, and to radially collapse to grip a collar of the drive element. The pulling fingers are configured to translate inside the housing to pull the drive element away from the sleeve as the stationary fingers contact the rim of the sleeve to form a bulb with the sleeve at a blind side of the hole.

A lockbolt collar feeder employing a resilient holder coupled to a linear actuator via a positioning arm, where the resilient holder can receive a lockbolt collar from a collar dispensing mechanism while disposed in a first position, and then when the linear actuator is extended the positioning arm extends and rotates the resilient holder to a second position in which the resilient holder can facilitate positioning the lockbolt collar onto a lockbolt for subsequent swaging. The linear actuator of the lockbolt collar feeder is configured to be coupled to a swaging tool, and thereby facilitates a method of positioning a lockbolt collar onto a lockbolt using the swaging tool.

A tool for installing a blind fastener. The tool includes a retention member and a gripping member that defines a longitudinal axis and is moveable relative to the retention member along the longitudinal axis, the gripping member further defining a receiving cavity that is elongated along the longitudinal axis, an axial opening into the receiving cavity, and a radial opening into the receiving cavity. The tool also includes a contact element at least partially received in the radial opening and a locking collar moveable relative to the gripping member along the longitudinal axis between at least a first position and a second position. In the first position the locking collar engages the contact element and urges at least a portion of the contact element into the receiving cavity. In the second position the locking collar is disengaged from the contact element.

A fastener application device comprising an hydraulically-operated tool head held by an operator and having an actuator trigger, a base structure having an air-operated power cylinder operatively attached to an hydraulic cylinder to supply hydraulic pressure to the tool head in response to operation of the actuator trigger. The tool head and base structure are connected only by air and oil lines that are long enough to allow the base structure to be supported on, for example, a workbench, requiring the tool operator to support only the weight of the tool head during a fastener installation sequence.

A non-path-variable element switch, in particular for connecting elements, which can be passed continuously by the elements being positive-lockingly guided, in particular head-guided, therein only in a feeding direction, from a plurality of profiled tracks into a number of profiled tracks, which is reduced compared to the plurality of profiled tracks. With the non-path-variable element switch, a plurality of feeding sources with different elements are connected to a processing tool. Thereby, the element switch is characterized in that it comprises no mechanically switchable elements.

Disclosed herein is a handle for a tool head. The handle includes a handle region having a first end and a second end. The handle region includes a first region adjacent the first end and adapted to receive a user's thumb and index finger, the first region including a trigger for actuating the tool head. The handle region also includes a second region adjacent the first region that is adapted to receive the user's middle finger and a first portion of the user's palm, and a third region adjacent the second region and adapted to receive the user's ring finger and a second portion of the user's palm. The handle region also includes a fourth region disposed between the third region and the second end that is adapted to receive the user's pinky finger and a third portion of the user's palm.

A fastening tool includes a housing, a handle, an anvil, a pin-gripping part, a motor, and a driving mechanism. The driving mechanism is configured to move the pin-gripping part along a first axis defining a front-rear direction, relative to the anvil. The driving mechanism includes a rotary member, a movable member, a driving gear and an idler gear. The rotary member has a driven gear formed on its outer periphery and is rotatable around the first axis. The movable member is connected to the pin-gripping part and configured to be linearly moved in the front-rear direction by rotation of the rotary member. The driving gear is configured to be rotated around a second axis extending in parallel to the first axis below the first axis. The idler gear is engaged with the driving gear and the driven gear.

A riveting tool chuck. The riveting tool chuck comprises a cylinder handgrip (1). A rotating member (2) and a transmission member (3) are disposed in the cylinder handgrip in a penetrating manner, the rotating member is axially positioned and circumferentially and rotatably connected to the cylinder handgrip, and the transmission member is circumferentially positioned and axially and movably connected to the cylinder handgrip, and the rotating member and the transmission member are connected by means of a thread structure (4). A safety valve mechanism (9) that can enable the thread structure to have a screw pair pretightening force is disposed between claw body top columns (8) and the transmission member, and in the process of forward rotation of the rotating member, the safety valve mechanism can enable the rotating member to implement screw pair transformation of a screw structure before the axial reaction force between the front end of each claw body (5) and the rear end of a cylinder guiding nozzle (7) is reduced to zero, so that backlash stroke of the screw structure is avoided. A riveting tool using the riveting tool chuck. The riveting tool chuck has the advantages that the structural design is reasonable, and the riveting tool chuck can be adaptive to a driving device containing power output, can provide a pretightening force for screw pairs, and has no backlash stroke.
