At this time, the emergency communication base station 1 is positioned and placed above the mounting base 2 through the positioning column 24. By pulling the rotation limiting abutting block 12 through the guiding rod 11 to cancel the limit on the rotation handle 7, the pressing spring 20 abuts the pressing block 3 to extend out of the mounting base 2, which drives the movable plate 22 to cancel the limit on the limiting block 25. The mounting abutting spring 32 abuts the limiting block 25 into the inside of the mounting limiting groove 28 to limit and fix the emergency communication base station 1. Conversely, the emergency communication base station 1 can be disassembled. The installation and disassembly can be completed by simple placement, saving a large amount of time and improving the emergency response efficiency.
