[0023] In this embodiment, the elevator shaft 1 is connected to the rescue box 6 via an internally arranged vertical guide rail 3, and one side of the rescue box 6 is limited by the vertical guide rail 3 to prevent the rescue box 6 from being offset.

[0024] In this embodiment, the supporting mechanism 5 includes a rescue box 6, a lifting rubber seat 9, an electric cylinder 13, an equipment support plate 14, and a guide groove 15. The rescue box 6 is arranged at the bottom end of the spring seat 11. The internal rectangular distribution of the rescue box 6 is provided with a guide groove 15.
