Abstract
A double-nut-screw type fixing connector based on stretching wedge blocks comprises a compression bolt, a compression nut, an external bracing bolt and at least one holding pin. The holding pins are movably arranged at the tail end of the compression bolt. The compression nut is connected to the compression bolt in a threaded mode. The external bracing bolt is operationally arranged in the compression bolt. When the double-nut-screw type fixing connector based on the stretching wedge blocks is not used, all holding pins do not protrude from the surface of the compression bolt; and when the double-nut-screw type fixing connector based on the stretching wedge blocks is used, the external bracing bolt outwards ejects the holding pins in the compression bolt so as to make the holding pins protrude from the surface of the compression bolt, and thus two connecting pieces are connected.
