| 摘要 |
Aspects of the invention are directed to a fastening device. A housing comprises a substantially planar coupling plate defining an aperture. A first engagement member passes through the aperture and defines a first arcuate surface with a first outwardly extending foot at a proximal end and a first protruding rim at a distal end. A second member is largely a mirror image of the first engagement member. A slide is adapted to be translated between a first position and a second position. When the slide is in the first position, the slide occupies a space between the first and second engagement members so that they are fixedly spaced apart. When the slide is in the second position, the first engagement member and the second engagement member are free to limitedly pivot in the housing to a condition in which the distal ends of the two engagement members meet. |
