A mechanical coupling device includes a spring retainer wound up around two tie rods inside a housing, a driving device supported on a bearing plate above the spring retainer and having an axle extended out of the housing through a center hole. Inserting a rod member through an opening on the housing into openings on two side sections and an intermediate section of the spring retainer causes locating spring leaves on the spring retainer to be spread out to hold the rod member firmly fastened. Rotating the axle of the driving device in one direction causes the spring retainer to be contracted in moving back the locating spring leaves and releasing the rod member; rotating the axle of the driving device in the reversed direction causes the locating spring leaves to be spread out to hold the rod member being inserted firmly fastened.
