Offset fastener

An offset fastener affixed to a mounting through hole of a first panel member for detachably locking said first panel member to a positioning hole of a second panel member, comprising:

• a socket comprising a socket hole and a positioning portion located at a bottom side thereof for fixation to said mounting through hole of said first panel member;
• a retaining shaft comprising a shaft body axially movably positioned in said socket hole of said socket and transversely movable in said socket hole of said socket between a center position and an offset position, at least one spring chamber transversely defined in said shaft body and exposed to the outside of said shaft body, each said spring chamber having accommodated therein a spring member and a floating ball, said floating ball being supported on said spring member and forced by said spring member into abutment against an inside wall of said socket that defines said socket hole, a positioning member axially extended from one end of said shaft body and adapted for inserting through said positioning hole of said second panel member when said retaining shaft is disposed in said center position and for locking said retaining shaft to said positioning hole of said second panel member when said retaining shaft is moved to said offset position;
• and
• a stopper member fastened to said retaining shaft and operable to move said stopper member between said center position and said offset position,
• wherein said socket further comprises a through hole cut through an opposing top side thereof in axial communication with said socket hole and having a relatively smaller diameter than said socket hole, an abutment surface internally defined in the connection area between said through hole and said socket hole for stopping against said shaft body of said retaining shaft to hold said shaft body in said socket;
• said retaining shaft further comprises a connection rod axially extended from an opposing end of said shaft body and extended through said through hole of said socket and connected to said stopper member outside said socket.
