Two L-shaped mounting brackets 210 are symmetrically mounted on the rear side of the gas detection device body 10 respectively and extend to the bottom of the gas detection device body 10 respectively. A sliding connecting member 220 is slidably arranged on the two L-shaped mounting brackets 210 together. A U-shaped mounting plate 230 is connected to the sliding connecting member 220. The U-shaped mounting plate 230 can slide to the back and bottom of the gas detection device body 10 through the sliding connecting member 220. Among them, when it is necessary to perform online monitoring of toxic and harmful gases in a polluted risk plot, the U-shaped mounting plate 230 is mounted on a drone or other mobile device, so that the gas detection device body 10 can be moved to the polluted risk plot for gas online monitoring, increasing the stability of the gas detection device body 10 when moving, and further increasing the stability of the online monitoring of the gas detection device body 10. By using the sliding connecting member 220 to slide on the L-shaped mounting bracket 210 to the back and bottom of the gas detection device body 10, the gas detection device body 10 can be installed according to the actual situation, improving the installation range.
