According to the utility model discloses bus connecting device through adopting first elastic component 222 and second elastic component 223, can realize bus connecting seat 100 and connection socket 200's quick assembly disassembly's effect, when bus connecting socket 200 or connection socket 200 appear unusually, but bus connecting socket 200 or connection socket 200 that direct replacement corresponds need not the while replacement, have improved installation effectiveness and replacement efficiency between bus connecting socket 200 and the connection socket 200 effectively.

The embodiments of the present invention have been described in detail with reference to the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made without departing from the gist of the present invention within the knowledge range of those skilled in the art.
