Abstract:
A fastening connector component and structure, mounting and removing methods, a crankshaft connecting rod mechanism, a track structure, a frame connecting apparatus, and a connecting method. The fastening connector component comprises a threaded rod (3) and a rotation-stopping sleeve (4). A first rotation-stopping part (11) arranged in the circumferential direction is provided at the periphery of a rotation-stopping resistant part. A rotation-stopping through hole (12) fitting the rotation-stopping resistant part is provided on the rotation-stopping sleeve (4). A second rotation-stopping part (13) fitting the first rotation-stopping part (11) is provided on the wall of the rotation-stopping through hole (12). A third rotation-stopping part (13) arranged in the circumferential direction is provided on the outer surface of the rotation-stopping sleeve (4) or two or more rotation-stopping through holes (12) are provided on the rotation-stopping sleeve (4). The second rotation-stopping part (13) fits the first rotation-stopping part (11) to restrain rotation of the threaded rod (3) relative to the rotation-stopping sleeve (4). This is advantageous in that the threaded rod (3) is restrained by the rotation-stopping sleeve (4) and thus is non-rotatable, and a thread connection does not come loose due to the threaded rod rotating in reverse, thus allowing the threaded rod (3) to be kept at a fastened position initially required.
