The outer wall of the rod body 101 is movably sleeved with the inner wall of the round hole 9.

[0026] The alarm body 1 is electrically connected to the control system. The control system includes an external main controller, which is connected to a wireless communication module and a power supply module. The main controller is provided with input terminals, and each input terminal is electrically connected to a corresponding signal acquisition module. Each signal acquisition module is electrically connected to a smoke-temperature composite detector 11 respectively. The main controller is provided with several output terminals, and each output terminal is electrically connected to a sprinkler fire extinguishing device, an alarm 12, a warning light 13, a control button 14 and a test button 15 respectively. When the smoke-temperature composite detector 11 senses the smoke in the environment, it is transmitted to the main controller through electrical connection. The main controller sends signals to each output terminal. The signal is sent to the sprinkler fire extinguishing device to spray water for fire extinguishing. The signal is sent to the alarm 12 to generate a warning sound. The signal is sent to the warning light 13 to make the fire warning light flash, so as to achieve the fire extinguishing effect.

[0027] Working principle: When in use, first, use the fastening bolt 20 to fix the extension plate 19 in the specified installation area, so as to achieve the installation of the mounting plate 2. Press the connecting block 602 to move inside the vertical rod 4. At this time, the first spring 601 is in a compressed state until the connecting block 602 is completely pressed into the vertical rod 4. Insert the vertical rod 4 into the engaging block 5. As the vertical rod 4 continuously moves inside the engaging block 5, use the rebound of the first spring 601 to eject the connecting block 602 from the inside of the through hole 26, so that the connecting assembly 6 can connect the vertical rod 4 and the engaging block 5. At this time, the insertion rod 18 is clamped with the slot 21, and the groove 16 is clamped with the convex rod 22. The sealing ring 24 is installed inside the inner ring plate 23 and the outer ring plate 17 to prevent dust from entering the inside of the alarm body 1. Then, since the alarm body 1 is externally connected to a main controller, the main controller is connected to a wireless communication module and a power module. The main controller is provided with input terminals, and each input terminal is electrically connected to a corresponding signal acquisition module. Each signal acquisition module is electrically connected to the smoke-temperature composite detector 11 respectively. The main controller is provided with several output terminals, and each output terminal is electrically connected to a spray fire extinguishing device, an alarm 12, a warning light 13, a control key 14 and a test key 15 respectively. When the smoke-temperature composite detector 11 senses the smoke in the environment, it is transmitted to the main controller through electrical connection. The main controller sends signals to each output terminal. The signal is sent to the spray fire extinguishing device for water spraying and fire extinguishing. After the signal is sent to the alarm 12, a warning sound is generated. The signal is sent to the warning light 13 to make the fire warning light flash, so as to achieve the fire extinguishing effect. Finally, when the alarm body 1 needs to be replaced, press the connecting block 602 to move inside the vertical rod 4. At this time, the first spring 601 is in a compressed state. By pulling the pull ring 103, the second spring 102 is stretched, and then the baffle 7 is pushed upward to make the baffle 7 block outside the connecting block 602 to prevent the rebound of the first spring 601. Then, the rod body 101 is penetrated through the inside of the round hole 9 from the cross plate 3, so that the rod body 101 restricts the movement position of the baffle 7, and controls each connecting assembly 6 one by one. After each connecting assembly 6 is retracted into the vertical rod 4, the vertical rod 4 is separated from the engaging block 5, and the alarm body 1 can be removed from the mounting plate 2 to achieve the disassembly effect of the mounting plate 2.
