Abstract: A connecting assembly includes: a connecting pipe, an inner wall of at least one end of the connecting pipe being provided with a pre-embedded nut, and the nut being coaxial with the connecting pipe; a connecting plate, the connecting plate being provided with a fixing hole; and a fastener, the fastener penetrating through the fixing hole and being in threaded fit with the nut. The connecting pipe is a light alloy component, and the connecting plate is a steel component. The connecting pipe is the light alloy component, the inner wall of at least one end of the connecting pipe is provided with the pre-embedded nut, and the fastener sequentially penetrates through the fixing hole on the connecting plate of a steel material and is in threaded fit with the nut at one end of the connecting pipe.
