Abstract
Disclosed is an improvement in a coupling mechanism for uniting two plates comprising a coupling member and associated apertures in the plates wherein the coupling member comprises a head portion and two legs integrally connected to the head portion and each having a stepped engaging portion on the periphery thereof, whereby when the two legs are inserted in the apertures of the two plates and rotated by 90.degree., the stepped engaging portions catch some selected parts of the circumference edge of the aperture of one of the plates, and clamp these plates in cooperation with the head portion, which is pushed against the other plate. The coupling mechanism according to this invention further comprises means to regulate the rotation angle of the shank of the coupling member at 90.degree., thus preventing the shank of the coupling member from overrunning the stop position at which the stepped portions catch selected parts of the circumference edge of the aperture of one of the plates to be coupled.
