The gas alarm detector body 7 is installed inside the support rod 4. The support rod 4 is arranged in an "L" shape, and the inner end of the support rod 4 is connected to the inside of the activity block 2 through a first spring 6. Three groups of support rods 4 arranged in an "L" shape are evenly arranged on the surface of the activity block 2. The use of the three groups of support rods 4 arranged in an "L" shape in cooperation with the first spring 6 can facilitate the clamping and supporting installation of the gas alarm detector body 7 by the support rods 4, and is convenient for quickly removing the gas alarm detector body 7 during maintenance;

[0027] Please refer to Figures 1-5 , on one side of the surface of the mounting block 1, a rotating lead screw 8 is arranged, and on the other side of the surface of the mounting block 1, a positioning rod 9 is arranged. The connection mode between the rotating lead screw 8 and the mounting block 1 is a threaded connection, and the connection mode between the mounting block 1 and the positioning rod 9 is a sliding connection. A rotating block is fixed at the top of the rotating lead screw 8. By rotating the rotating block at the upper end of the rotating lead screw 8, the rotating lead screw 8 can drive the mounting block 1 to move in a threaded manner, so that the mounting block 1 slides up and down on the positioning rod 9, facilitating the adjustment of the height position of the gas alarm detector body 7 during use. Both the upper and lower ends of the rotating lead screw 8 and the positioning rod 9 are rotatably connected to a connection block 10. The outside of the connection block 10 is provided with a mounting slide rail 11, and both ends of the outer side of the mounting slide rail 11 are fixed with mounting plates 12. Tooth blocks 13 are evenly fixed on the inner surface of the mounting slide rail 11.
