A fastener operating structure includes a holding base and a fastening-connecting unit. The holding base is disposed at a first object. The fastening-connecting unit is movably disposed at the holding base. The fastening-connecting unit is fastened to a second object. Consequently, the holding base is disposed at the first object, and the fastening-connecting unit is coupled to or removed from the second object, so as to couple together and separate the first and second objects repeatedly and quickly.

In order to provide a connecting device for connecting two components, which is simple to manufacture and enables a stable and reliable connection of the two components, it is proposed that the connecting device comprises a main body which comprises a receiving channel extending through the main body for accommodating a fixing element, wherein the receiving channel is preferably accessible at one end by way of an insertion opening of the main body and/or preferably at a (further) end by way of a fixing opening of the main body, wherein the main body preferably further comprises an actuating opening that is different from the insertion opening and/or the fixing opening, by way of which in particular the fixing element arranged in the receiving channel is preferably accessible for the actuation thereof.

A system for fastening two components is disclosed having a mechanical connection device including two tenons that each extend from an opposite face of an interposed plate, each of the tenons having two appendages forming coupling arms, each appendage being positioned on either side of the tenon. The appendages of one tenon being positioned in a different longitudinal direction than the appendages of the other tenon, each appendage having a coupling component to connect to a device for locking the tenons and two end fittings that each have a slot in which each of the tenons of the connection device is able to be fitted, each appendage protruding out of the slot on either side thereof.

An electrode plate (100) and a wearable defibrillation device are disclosed. The electrode plate (100) includes a hermetic shell (110), a capsule (120) and a sealing structure (130). The hermetic shell (110) has an inflation port (111) and an overflow aperture (112). The overflow aperture (112) is disposed in a conductive exposed surface (113) of the hermetic shell (110). The capsule (120) is provided in the hermetic shell (110) and defines a cavity (122) for storage of a conductive paste therein. The cavity (122) defines an inlet orifice (123) and an outlet orifice (124). The overflow aperture (112) is disposed at the outlet orifice (124). A sealing component (132) of the sealing structure (130) is positioned at the overflow aperture (112) and configured to close the overflow aperture (112) and the outlet orifice (124) when the hermetic shell (110) is not inflated. The force applying component (131) of the sealing structure (130) is disposed on the hermetic shell (110) and then is connected to the sealing component (132) after being inserted into the capsule (120) through the inlet orifice (123). The force applying component (131) is configured to pull the sealing component (132) as a result of inflation and expansion of the hermetic shell (110) and thus open the overflow aperture (112) and the outlet orifice (124) and bring them into communication. As a result, the conductive paste is allowed to flow through the outlet orifice (124) and the overflow aperture (112) onto the exposed surface (113). During cardiac defibrillation of the electrode plate (100), the conductive paste can automatically applied to provide a patient with timely protection, and the conductive paste can be released in a reliable and safe manner.

Discussed is a bolting device including an operation part disposed on a table; a jig disposed on the table to contact an object to be bolted in which a bolt hole is defined, the jig including a through-hole for guiding a bolt to the bolt hole; a guide inserted to the through-hole, the guide having a hollow shape to accommodate the bolt therein, the guide having an inclined inner surface with a shape having an internal diameter that gradually decreases in a downward direction to maintain verticality of the bolt, and the guide further having a portion cut in a movement direction of the bolt so that the inner surface is elastically opened when the bolt is moved downward; and an elastic part in contact with an outer circumferential surface of the guide to elastically support a surrounding portion of a cut portion of the guide.

A substrate usable with a double-side adhesive strip to suspend the substrate to a wall surface. The substrate can have one or more access holes located within an outer perimeter of the substrate. Each access hole has an inner perimeter inwardly of the outer perimeter that is sized and shaped to allow a tab of the double-sided adhesive strip to be extracted through the inner perimeter, after the substrate is suspended on the wall surface. Various articles can attach to the suspended substrate, such as through magnetic attachment, a hook, or a shelf.

In implementations of a pressure lock retention fastener, the fastener assembly includes an insert sized for insertion into a fastener hole in a first panel. The fastener assembly has a threaded collet sized to slide in the insert and has expandable flanges that extend below the insert. The expandable flanges are sized for insertion into an aligned hole in a second panel. The fastener assembly also includes a screw installable through the insert to engage the threaded collet. The screw exerts a force that pushes the expandable flanges outward as screw rotation drives the screw into the threaded collet, and ridge locks of the expandable flanges seat up against the second panel effective to fasten the panels together. In implementations, a plate is installable between the panels with slotted holes having anti-rotation tabs that prevent a fastener assembly from spinning in the panel holes.

A fastener system shifting shear stresses away from a collet body and provides clamping action to targeted structures. The fastener system includes feet in the collet body that mate with openings in a sleeve at least partially surrounding the collet body. The sleeve or the collet body includes interior threads that engage with a stud that is configured to extend through the collet body and bend the feet such that they project outward from the sleeve openings in an engaged configuration.
