The connecting assembly 30 is suitable for various use scenes needing quick assembly and disassembly, and has the advantages of high applicability, easiness in operation and the like.

Although some specific embodiments of the present application have been described in detail by way of example, it should be understood by those skilled in the art that the above examples are for illustration only and are not intended to limit the scope of the present application. It will be appreciated by those skilled in the art that modifications may be made to the above embodiments without departing from the scope and spirit of the present application. The scope of the application is defined by the appended claims.
