First, two sets of L-shaped clamping plates 207 are penetrated through the through groove 208 until the detector body 3. The bottom is in contact with the top of the return frame 201. Then, manually rotate the handle 204 counterclockwise. The handle 204 drives the two-way threaded rod 205 to rotate through the rotating shaft 203. Since the two-way threaded rod 205 is threadedly connected with two sets of push plates 206, and the two sets of push plates 206 are slidingly connected with the guide rail 210 through the sliders 209 on their respective outer sides. Therefore, when the two-way threaded rod 205 rotates counterclockwise, the two sets of push plates 206 can drive the two sets of L-shaped clamping plates 207 to face to both sides of the through groove 208. Move, so that two sets of L-shaped clips 207 are in the detector body 3, and then the support mechanism 1 is connected with the detector body 3 without any tools, and the connection process is relatively simple. Secondly, when in use, if the bottom occupies If the ground area is too small and the support is not stable enough, lift it up, then unscrew the locking bolt 110, rotate the holding cylinder 108 clockwise, and move down along the T-shaped threaded rod 109 while the holding cylinder 108 rotates, Then drive the four groups of first connecting frames 104 to move. When the first connecting frames 104 move, the ends of the struts 105 rotate and their inclinations change. When the inclinations of the struts 105 change, the struts will be pushed outwards. 103, the end of the support rod 103 rotates in the support frame 102, and then changes its support angle, thereby increasing the support area at the bottom. If it is necessary to reduce the support area at the bottom, just rotate the holding cylinder 108 counterclockwise, so that According to the actual needs of the site, the support area of the bottom can be regulated. When the adjustment is completed, the locking bolt 110 is re-tightened to fix the position of the holding cylinder 108. Finally, the probe 4 is fed into the air, and the detector body 3 The real-time concentration content in the air is displayed on the display, and the content not described in detail in this description belongs to the prior art known to those skilled in the art.
