[0028] Reference Figure 1-3 A clamping mechanism for limiting the exhaust gas emission pipe 3 is arranged on the outer wall of one end of the intake pipe 2 away from the monitoring device body 1, and the clamping mechanism includes a first threaded rod 12 connected to a clamping plate 13. Side plates 11 are fixedly arranged on both sides of the outer wall of the end of the intake pipe 2 away from the monitoring device body 1. The two first threaded rods 12 are threadedly sleeved in the corresponding side plates 11. The clamping plate 13 is rotatably arranged on the end of the first threaded rod 12 close to the exhaust gas emission pipe 3. One side of the clamping plate 13 is in conflict with the outer wall of the exhaust gas emission pipe 3. A sliding rod 14 is movably sleeved inside the side plate 11 and on one side of the first threaded rod 12. One end of the sliding rod 14 is fixedly connected to the clamping plate 13, so that the clamping plate 13 cannot rotate, that is, it can slide stably.
