[0027] The staff can slide the limiting sleeve 7 and the positioning sleeve 6 along the support rod 2 and the positioning plate 3, and then adjust the height of the carbon dioxide sensor 8. While sliding the positioning sleeve 6, the height of the positioning sleeve 6, the limiting sleeve 7 and the carbon dioxide sensor 8 can be intuitively observed through the scale 12.

[0028] After adjustment is completed, the positioning assembly 9 is used to position the positioning sleeve 6 on the positioning plate 3, and then fix the height of the carbon dioxide sensor 8.

After the height of the positioning sleeve 6, the limiting sleeve 7 and the carbon dioxide sensor 8 is adjusted, the positioning pin 95 is loosened, the spring 98 pushes the clamping block 96 to be re-clamped into the corresponding clamping groove 93, the fixation of the positioning sleeve 6 is realized, and the carbon dioxide sensor 8 starts to collect data at the new height.
