A fastening connector structure comprising a parent (1), an attachment (2), and a fastening connector component. The fastening connector component comprises a threaded rod (3) and a rotation-stopping sleeve (4). Provided on the wall of a first rotation-stopping hole (20) and/or the rotation-stopping sleeve is an extraction structure for extracting the rotation-stopping sleeve. The threaded rod runs through the attachment to be mounted together with the parent. The rotation-stopping sleeve is mounted on the exterior of a rotation-stopping resistant part of the threaded rod and within the first rotation-stopping hole and is axially limited. A first rotation-stopping part (11) at the periphery of the rotation-stopping resistant part of the threaded rod fits a second rotation-stopping part (13) on the wall of the rotation-stopping hole to restrain rotation of the threaded rod relative to the rotation-stopping sleeve. A third rotation-stopping part (14) at the periphery of the rotation-stopping sleeve fits a fourth rotation-stopping part (21) on the wall of the first rotation-stopping sleeve to restrain rotation of the rotation-stopping sleeve relative to the attachment. The threaded rod is non-rotatably mounted together with the attachment and the parent, thus preventing the threaded rod from rotating in reverse and coming loose, and allowing the rotation-stopping sleeve to be extracted conveniently, quickly, and reliably from the first rotation-stopping hole. |
