1. A connecting structure, comprising a coating component, an expansion component and a threaded first fastener, wherein the coating component is provided with a storage cavity; a part of the expansion component is stored in the storage cavity; the coating component is provided with a threaded first through hole; and the expansion component is provided with a second through hole;
the expansion component has a rotary state and a fixed state relative to the coating component; when the expansion component is in the rotary state relative to the coating component, the expansion component can be rotated relative to the coating component; the first fastener can pass through the first through hole and extend into the second through hole so as to make the expansion component expand; the outer surface of the expansion component is pressed against the inner surface of the coating component so as to fix the expansion component in the coating component; when the expansion component is in the fixed state relative to the coating component; and
the connecting structure further comprises a threaded second fastener; the coating component is provided with a threaded third through hole opposite to the first through hole; the expansion component is provided with a fourth through hole opposite to the second through hole; and the second fastener passes through the third through hole and extends into the fourth through hole.
