A locating structure includes a fixture and a locating member. The fixture includes a body and a fastener, wherein the fastener is movably provided at the body. The body is configured to assemble with a first object, and the fastener is configured to fasteningly connect to a second object or be removed from the second object. The locating member is movably assembled with the body, and the locating member may press against or drive the fastener to locate the fastener at a located position, or the locating member may move or drive the fastener to locate the fastener at a locating-released position. Thus, the locating member may be moved to locate the fastener at the located position or at the locating-released position, so as to complete coupling or separation of at least two objects, achieving the effect of repeated quick coupling and separation.

A locking device (100) is operable to lock a tool (150) in an opening. The locking device includes a base (104) positionable with respect to a lifting member (152) of the tool when a first end of the lifting member is positioned within the opening. The locking device also includes a lift (106) coupled to the base for movement relative to the base. The lift includes an interface portion (110) coupleable to the lifting member such that the lifting member is moveable with the interface portion in an extraction direction of the opening when the lift is moved from a first position to a second position relative to the base.

A structure conducive to reduction of fastening element height, including a fastener and a body portion. The fastener has a head portion, fastening portion, rod portion, resilient component and resilient component placement portion. The body portion and fastener are movably fitted together. Therefore, the body portion is fitted to the first object, such that the fastening portion can be fastened to the second object and removed from the second object, thereby allowing at least two objects to be coupled together and separated repeatedly and rapidly.

Push nuts for cars, comprising a head having a member contact surface formed protruding in left and right sides, and having a fastening hole formed penetrating at the center; and a body having formed penetrating at the center, a fastening hole having the same inner diameter and center as the fastening hole which is formed at the head, characterized in that the body and the head are connected to a connecting bridge that elastic deformation is performed outwards, and the head and the body connected with the connecting bridge respectively have a head axial force support and a body axial force support formed protruding toward a space, the head axial force support and the body axial force support having fastening holes having the same center as the fastening holes respectively formed penetrating.

Fastener embodiments of the invention comprise a freely translatable collet body, which at least partially translates within an auxiliary structure, and further comprise a captive threaded screw for rotationally engaging with the collet body to transform rotational movement into translational movement through substantial arresting of collet body rotation by way of an anti-rotation means. The screw comprises a free-spin feature that functionally, but not physically, decouples a drive tool from the collet body.

The present invention concerns a fastener (110) for the temporary assembly of at least two previously drilled structures (112) comprising: a hollow body (122) comprising a bearing surface (40); elastic clips (24) which are movable relative to the body and which form a projection relative to the bearing surface; a spacer (26) around which the elastic clips are positioned; a connecting element (130), extending within the body and secured to the elastic clips (24); and an actuating element (132) linked to connecting element by a thread/tapping (67, 84). The connecting element is traversed by a lateral opening (70) axially extended between two closed ends (72, 74); and the fastener also comprises a transverse stop (28) secured to the spacer, the said stop being capable of sliding between the axial ends of the said lateral opening.

A fastener includes a hollow tubular body, a hollow leg member translatable within the body having a plurality of resilient legs each with a head at the distal end for engaging with a work-piece. The fastener also includes an actuating member for biasing the resilient legs, where the actuating member includes a profiled tip, the profile of the tip includes a ramp for expanding the legs and a stop, and the stop and legs are arranged such that the stop can engage with an end surface of the legs to draw the legs further into the body and not bias the legs radially outward.

A fastener structure includes a body portion, a control portion and a fastening portion. The control portion is movably fitted to the body portion. The control portion has a head portion and a limiting portion. The fastening portion is movably disposed at the body portion. The limiting portion is adapted to limit the fastening portion. Therefore, the body portion is disposed at the second object, and the control portion causes the fastening portion to be coupled to or separated from the first object, so as to couple together and separate at least two objects repeatedly and rapidly.

A tacking device for a temporary fastening of components has a sleeve having a first end, a second end, an axial hole and a radially projecting collar at the first end, and an elongate mandrel having a head end and a tensioning end. The mandrel can be inserted into the axial hole at the second end of the sleeve, can be brought into stop contact with a sleeve rim surface by the head end and projects beyond the first end from the sleeve in the inserted state. A holding unit is designed to hold the mandrel when the tacking device is inserted into an opening of a component. The sleeve has a deformable material, which is squashed against the component when is inserted into an opening of a component. The mandrel has a predetermined breaking point with a weakened cross section, positioned between the head end and the tensioning end.

The present invention concerns a fastening socket (112) for assembling at least two previously drilled structures, said socket comprising a substantially cylindrical body (34) and an enlarged head (35); said enlarged head comprising first mounting surfaces (42, 46) suitable for being assembled to a first installation component and for preventing said first installation component from rotating about the main axis. The socket comprises a first substantially cylindrical recess (40) extending along the main axis from the first end, said first recess ending at a planar shoulder (44) substantially perpendicular to said main axis, the first recess and the planar shoulder being received inside the enlarged head, the first mounting surfaces (42, 46) being formed by an inner surface of the first recess.
