Abstract: An exemplary connecting structure (30), for connecting a first metal element (31) and a second metal element (32), includes a threaded weld bushing (34) and a fastener (36). The threaded weld bushing includes a main body (340) for being spot welded to the first metal element with a plurality of weld joints, and a collar (342) extending from one end of the main body for abutting the first metal element and connecting to the second metal element, and a fastener latching portion (346) defined in the main body and the collar. The fastener is configured for engaging with the fastener latching portion so as to prevent the second metal element detaching from the threaded weld bushing.
