[0028] The second ladder body 20 is provided with a fixing assembly, which is used for fixing the first ladder body 10 and the second ladder body 20. The fixing assembly includes a socket 41 opened on the end wall of the second ladder body 20, and the interior of the first ladder body 10 is provided with a mounting groove 44 which is in communication with the end wall of the first ladder body 10.
