An ergonomic bucking bar is disclosed herein. The ergonomic bucking bar includes a bar body having a proximal end and a distal end. The proximal end includes a plurality of apertures formed therein for reducing weight of the bar body at the proximal end. The ergonomic bucking bar includes a compliant hand grip positioned over the proximal end of the bar body for reducing vibrations transmitted through the bar body during a riveting operation using the bucking bar. Optionally, the distal end includes at least one aperture formed therein for receiving an insert to increase the weight of the bar body at the distal end.

A die chanter for a die of a joining device, a die dome adapted to the die and a method for removing a die of a joining device and a method for inserting a die into a joining device. The die has a head having upper and bottom sides, and a shaft extending from the bottom side and receivable and lockable in a dome without rotation. The shaft comprises: at least one first web forming an undercut on two sides by which the shaft is lockable in the dome by a linear inserting movement, at least one second web, the length of which is adaptable to a diameter of the dome to ensure a lateral guiding of the shaft in the dome and which is arranged between the head and the first web, and an ejection surface by which the die can be moved out of the dome.

The present invention discloses a one-hand handled riveter, which includes a housing with a left handle on the bottom, and a right handle. The mentioned left handle and right handle are all covered by a handle cover. The mentioned housing is installed with a rivet head and the rivet head is equipped with a pull rod on the rear end. The right handle is connected to the pull rob by the top end. Both sides of the top end of the right handle, are equipped with a support arm. The support arms are connected with the pull rod through a positioning shaft by the top end, and the two support arms are connected to a connecting rod through a pin shaft by the bottom end. And a connecting shaft is arranged to the end of the two connecting rod far away from the support arm. Two L-shaped connecting pieces are respectively connected to two ends of the connecting shaft. A connecting hole is arranged to the front and rear ends of the L-shaped connecting piece, and the connecting shaft passes one of the holes. And the rear end of the L-shaped connecting piece is connected to the fixing seat on the rear end of the pull rod by screw connection. The invention can achieve the working mode for screw riveter and nut riveter by selecting the installation position of the connecting hole on the L-shaped connecting piece.

A quick-disassemble snapping device of a rivet gun has a front sleeve, a rear sleeve, a snapping assembly, and a retaining assembly. The front sleeve has multiple positioning recesses. The rear sleeve is coaxially connected with the front sleeve and has at least one mounting recess. The snapping assembly is mounted in the front sleeve and the rear sleeve. The retaining assembly has a locking ring. The locking ring is mounted around the rear sleeve and has at least one engaging tooth mounted through the at least one mounting recess of the rear sleeve and engaging in at least one of the positioning recesses of the front sleeve. The quick-disassemble snapping device can be used in a pneumatic, manual, or electric rivet gun and has a stable structure. No tool is needed for disassembling the snapping device and the snapping device can be easily disassembled to be cleaned.

A method for installing a fastener by positioning a cap around the fastener, spraying a cooling agent from a sprayer of a cooling system. The fastener may have a top portion including a dielectric material. The cooling system may be configured to cool the top portion of the fastener to stiffen the top portion. A tool may be configured to install the fastener in a structure after cooling, while retaining the cooling agent within the cap.

The present invention discloses a gecko gun, which includes a housing with a left handle on the bottom, and a right handle. The mentioned left handle and right handle are all covered by a handle housing. The mentioned cover housing is installed with a U-shaped seat at the top end. The top end of the right handle is rotated with the top end of the housing through a spindle. The top end of the right handle is installed with a link mechanism, which is covered by the mentioned housing and fixed to the housing via screws. The link mechanism includes a first linkage assembly linked to the top end of the right handle and a second linkage assembly connected to the first linkage assembly, and the second linkage assembly is used to drive the U-shaped seat to shift forward and backward. Thereby the designed gecko gun will help achieve the effect of energy saving.

The invention relates to a hand-held pulling and compression device for driving interchangeable tools, with a drive unit comprising a battery-operated electric motor, a screw drive with a threaded spindle connected to the drive unit and rotatably mounted on a housing body, and a threaded nut mounted rotatably on the threaded spindle and non-rotatably on the housing body via a bearing unit, and a coupling unit connected to a tool holder for transmitting tensile and compressive forces resulting from the direction of rotation of the threaded spindle from the threaded nut to the tool holder. In order to provide a hand-held pulling and compression device that can be used flexibly, it is provided that the housing body has a connection section for detachable fixing of a tool device to the pulling and compression device.
