A rivet feeding system having a hopper, an inclined rail, and a fastening assembly is disclosed. The hopper accommodates a plurality of rivets, each having a head and a tail, in a barrel rotatably mounted to a stationary back. The hopper permits a single rivet to exit the hopper at a time and the exiting rivets are received by the inclined rail. The inclined rail has a channel defined by two sidewalls and the channel is sized to accommodate the rivet tail and the two sidewalls are positioned to support the rivet head. The inclined rail is positioned to receive rivets in a first orientation and to deliver rivets to the fastening assembly in a second orientation that is distinct from the first orientation. The fastening assembly includes a stationary anvil positioned below a moveable punch and a pair of pivotable jaws positioned between the anvil and the moveable punch.

A fastener placement tool has a mandrel able to place a series of captive rivets in sequence. The tool employs a single electric motor capable of driving the tool into either a first cycle for rivet placement, to a second cycle for selective release of the mandrel form the tool for rivet replenishment. The tool includes a user-operable switch actual to select which of the first or second cycle the tool is to operate.

The disclosure relates to a method for screwing a locking ring onto a threaded bolt, wherein a coupling device for being threaded into the threaded bolt is driven in rotation by a rotary drive, and wherein the locking ring is then screwed onto the threaded bolt, which is fixed by the coupling device, by a locking ring holder which is driven in rotation by the rotary drive. The disclosure likewise relates to a method for screwing a locking ring comprising a fastening part and a tear-off part onto a threaded bolt, wherein a removal gripper grips the tear-off part and removes the tear-off part after the tear-off part has been torn off. The disclosure further relates to a screwing apparatus for executing a method according to the disclosure.

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.

The present invention discloses a one-hand-handled rivet gun, which has a handle seat with a through hole, a folding mechanism hinged to the handle seat and a pulling rod connected to the folding mechanism. The mentioned pulling rod is coated by a housing, and is equipped with a riveting gun tip assembly on the front end. A fixed sleeve is mounted on the front end of the housing of the pulling rod, and a guiding nipple is mounted on the front end of the fixed sleeve. The mentioned folding mechanism comprises two folding rod assemblies symmetrically mounted behind both sides of the rear end of the pulling rod, and the two folding rod assemblies include a front curved link and rear curved link hinged to each other. A handle cover is connected to the rear end of the rear curved link, and the front curved link is fixed to the pulling rod by the front end and hinged to the front end of the handle seat. Therefore, the invented one-hand-handled rivet gun can be used with only one hand, which is easy for people to use.

A blind rivet arrangement (1) is described, comprising multiple rivet bodies (3, 3a, 3b) arranged in succession on a mandrel (2), the mandrel (2) having a mandrel head (8) with an outside diameter which is greater than an inside diameter of the rivet bodies (3, 3a, 3b). The aim is to provide an inexpensive way to produce a blind rivet arrangement that works effectively. To this end the mandrel (2) and the mandrel head (8) are designed as parts that are produced separately and joined together.
