The invention relates to a device (10) for manually introducing holes and/or rivets into a workpiece, said device having a body (20) which has a working region (12) into which a workpiece which is to be provided with holes and/or rivets can be introduced. In the working region (12), a tool plate (21) is provided, into which a tool (60) can be introduced, and a tool receptacle (31) is also provided, which is arranged on a slide (30) and into which a counter tool (61) can be introduced. The slide (30) is movable towards the tool plate (21) and away therefrom, the workpiece for machining being arrangeable on the working region (12) between the tool plate (21) and the tool receptacle (31). The invention comprises a handle (40) which is pivotable about a first pivot axis (41) in order to move the slide (30). The slide (30) is arranged away from the tool plate (21) in a release position (30.1) when the handle (40) is in its first position (40.1), and, as the handle (40) is pivoted into its second position (40.2), is moved towards the tool plate (21) into its working position (30.2), in which the tool (60) and the counter tool (61) are operatively connected to one another. Lastly, a stop (11) is provided on the body (20), which, in the second position (40.2) of the handle (40), cooperates with a counter stop (42) on the handle (40) in order to delimit the second second position (40.2) of the handle (40) and thus the movement of the slide (30) towards the tool plate (21) into its working position (30.2). The invention now proposes that the stop (11) and thus the working position (30.2) of the slide (30) are adjustable.

The present invention discloses a nut riveter comprising a front riveter seat with a cavity, a rear riveter seat arranged in the cavity of the front riveter seat and located at a rear end of the front riveter seat, a nut adjusting mechanism arranged at a front end of the front riveter seat, a nut riveting rod installed in the nut adjusting mechanism, wherein two sides of the rear riveter seat are each connected to a handle through a connecting rod; a pull rod seat located in the cavity of the front riveter seat, wherein a pull rod is inserted into the pull rod seat, wherein a rear end of the pull rod is connected with a pull rod retractable mechanism.

A construction support structure contains: a plurality of first hollow posts, plural second hollow posts, and at least one platform. Each first hollow post includes at least one groove, and each groove has a first width section and a first narrow section, wherein a horizontal width of the first width section is more than the first narrow section. Each second hollow post includes two locking protrusions, and a distance between two sides of each locking protrusion is more than a distance between a top end and a bottom end of each locking protrusion, wherein each locking protrusion has a connecting section, a diameter of which is less than the distance between the two sides of each locking protrusion and the distance between the top end and the bottom end of each locking protrusion, and the connecting section corresponds to the first narrow section of each first hollow post.

A multi-purpose and simple riveting tool comprises a male member, a female member and at least one rotating device, wherein the male member comprises a fixing part and a riveting part; the fixing part comprises an accommodating groove with a threaded part, and the female member comprises an inner cavity with a depth; the rotating device comprises a rotating shaft, at least a part of which has a threaded part; the male member penetrates through the inner cavity, and the inner cavity is configured to only allow the male member to move axially in the inner cavity; and the rotating shaft is screwed into the accommodating groove, so that the rotating device drives the axial movement of the male member in the inner cavity when rotating around at least one rotation axis.

A system and method for drilling a hole in a vehicle structure and installing a fastener in the hole. A drill plate having openings and associated machine-readable elements is positioned on the structure. A drill gun is positioned in a particular opening and reads hole information from the associated element, and a computer determines whether the drill gun is properly set-up to drill the hole. A fastener insertion gun is positioned in the particular opening and reads fastener information from the element, and the computer determines whether the hole has been drilled and, if so, whether the fastener insertion gun is properly set-up to insert the fastener. A fastener delivery subsystem stores, tracks, and delivers fasteners to the fastener insertion gun. A system computer monitors the drilling of every hole, the insertion of every fastener, and the overall operation of the fastener delivery subsystem.

A blind rivet setting tool including a clamping assembly for releasably clamping a nosepiece in place such that a blind rivet can bear against the nosepiece while the mandrel thereof is pulled; and a method of changing nosepieces using the clamping assembly.

A blind rivet setting tool including a nosepiece storage unit removably attached to a housing feature of the tool, wherein the nosepiece storage unit is configured to hold a plurality of nosepieces and defines a mandrel receiving opening which aligns with an exit opening of the tool such that the broken mandrel of a set rivet can be moved through the mandrel receiving opening in use; and method of using the nosepiece storage unit.
