Therefore, in some embodiments, the second elastic member can also be configured as a compression spring and an elastic steel plate.

[0070] In the embodiment of the present invention, the purpose of this arrangement is that relevant technicians can swing the first support rod 601 relative to the second door 3 to make the length direction of the first support rod 601 and the second support rod 602 perpendicular to the plane of the second door 3, thereby supporting the second door 3 when the plane of the second door 3 is in a horizontal state.
