Abstract:
1. A floating fastener, comprising: a base member having an accommodation chamber defined in one end thereof, a tubular mounting neck axially extended from an opposite end thereof for fastening to an external first board member, an axial hole axially defined therein in communication between said accommodation chamber and the inside space of said tubular mounting neck and a shoulder located on an inside wall thereof between said axial hole and said tubular mounting neck; a locking rod set mounted in said base member and adapted for locking said external first board member to an external second board member, said locking rod set comprising: a limiter block fixedly mounted in said accommodation chamber, said limiter block having an non-circular constraint hole cut through top and bottom sides thereof in axial alignment with said axial hole of said base member; a locking rod inserted through said axial hole of said base member and said non-circular constraint hole of said limiter block, said locking rod comprising an elongated rod body, said elongated rod body having a non-circular cross section fitting the configuration of the non-circular constraint hole of said limiter block, a locking tip axially extended from one end of said elongated rod body, a stop flange extending around the periphery thereof between said elongated rod body and said locking tip and stoppable at said shoulder inside said base member, and an annular groove extending around a middle part of the periphery of said elongated rod body; a spring member sleeved onto said elongated rod body of said locking rod and stopped between said stop flange of said locking rod and said limiter block; and a knob fastened to one end of said elongated rod body of said locking rod and disposed outside said base member and operable to move said locking rod axially relative to said base member, and to rotate said locking rod, when said locking rod is moved with said knob to the elevation where said annular groove of said locking rod is kept in said non-circular constraint hole of said limiter block, between a constrained position where said locking tip of said locking rod is received inside said base member and said locking rod is stopped by said limiter block from axial movement relative to said base member and a released position where said locking rod is movable axially relative to said base member.
