The present invention provides a rivet gun including a first handle, a second handle, a transmission mechanism, and a clamping-pulling mechanism. The first handle is fixedly connected or integrated with a housing limiting the clamping-pulling mechanism, and the second handle is rotatable around a first fixed shaft relative to the first handle; the clamping-pulling mechanism includes a pull rod with gear grooves thereon; the transmission mechanism includes a gear member with a gear end rotatable around a second fixed shaft, the gear end of the gear member being configured to engage with the gear grooves on the pull rod; and the second handle is connected to the transmission mechanism, and configured to drive the gear member of the transmission mechanism to rotate when the second handle is rotated and opened relative to the first handle such that the gear member pushes the pull rod forward by engagement between the gear end and the gear grooves, and to drive the gear member of the transmission to rotate when the second handle is rotated and closed relative to the first handle such that the gear end of the gear member pulls the pull rod backward by engagement between the gear end and the gear grooves.

A device is disclosed for supplying swageable collars from a magazine to a swaging tool such that the collars may be affixed to the shanks of lockbolts in a series of application steps. The feeder device can be mounted on the nose assembly of a swaging tool so that collar feeding and swaging can be accomplished in a single-handed operation. The feeder device responds to contact pressure against a work surface during a collar placement maneuver to release a collar from a presentation position for normal swaging. Releasing pressure on the workpiece allows a lower assembly of the feeder device to lift the next collar available from a magazine into the presentation position for application to the next lockbolt shank in a series of lockbolts to be finished.

A method and apparatus for installing a fastener is provided. The apparatus comprises a plate system and an air system that is connected to the plate system. The plate system has a plurality of air passages and at least one opening. The air system directs air through the plurality of air passages, out of the opening, and in a selected direction substantially parallel to a surface of a structure into which a fastener is to be installed such that the air impinges on an exposed portion of a shaft of the fastener.

A portable test instrument for a rivet nut setting tool is disclosed, and the portable test instrument includes a shell body, a circuit module disposed in the shell body, and a strain gauge having a part located in the shell body and electrically connected to the circuit module, and a display device. An end of the strain gauge is exposed to the shell body and used to mount with the rivet nut setting tool. The strain gauge can change a value of a signal transmitted to the circuit module when being forced to deform. The display device is disposed on the shell body and electrically connected to the circuit module, and configured to display data measured by the strain gauge.

A method for repairing rivet tape includes steps of cutting portions of the rivet tape on each side of a break to define at least three aligned coplanar rivet tape edges, abutting the at least three aligned coplanar rivet tape edges to define a seam, and joining the at least three aligned coplanar rivet tape edges to one another. The seam may define a Z shape. One or more rivets may be removed to expose rivet apertures on each side of the break before the steps of cutting, abutting, and joining. The step of joining is accomplished by at least one adhesive strip disposed on a surface of the rivet tape and dimensioned to overlie the at least one or more exposed rivet apertures. Adhesive strips may be disposed on each opposed surface of the rivet tape length. In other aspects, workstations comprise devices for practicing the described methods.

An apparatus, system, and method for removing and installing slasher teeth in a saw are provided. The apparatus has a first body and a second body having a space formed therebetween, wherein a slasher tooth is positionable within the space. At least one locator pin is connected to at least one of the first and second body, the at least one locator pin contactable to the slasher tooth to locate the first and second body relative to the slasher tooth. At least one engagement device is positioned on one or both of the first and second bodies, the at least one engageable device being actuatable, whereby actuation of the at least one engagement device moves it relative to the first and second bodies and into the space where the at least one engagement device contacts a rivet positioned between the slasher tooth and a saw body.
