[0031] As shown in FIG. 1, Figure 1 , Figure 2 and Figure 4As shown, the slider 5 is provided with a limiting pin 52 on the front lower side, which limits the bottom of the swing rod 6. The end of the swing rod 6 close to the fixed pin 51 is screwed through the second locking bolt 8, which locks and fixes the rotation angle of the swing rod 6.

The upstream sampling port 15 is connected through an independent pipeline. Based on the upstream detection concentration and the downstream scanning detection, a leak is determined.

The gas flowing inside the pipeline will first pass through the filter plate 3 when it passes through the downstream sampling port 16 to isolate foreign objects such as lint and impurities in the gas.

[0036] Simultaneously, when using or needing to replace parts of probe structure 4, handle 43 can be placed inside the clamp 61 to support probe structure 4 for easy operation. Slider 5 can move back and forth along the track rod 19 and then be locked and fixed by the first locking bolt 7. Then, the angle of swing rod 6 is controlled and locked and fixed by the second locking bolt 8 to adjust the positioning position of clamp 61, thereby controlling the position of supporting probe structure 4. Conversely, when not needed, slider 5 can be moved backward and swing rod 6 can be rotated to a horizontal position, limited by limit bolt 52 to maintain stability and reduce storage space.
