Since the density of gas is lower than that of air, it usually gathers above the mine or exploration hole. Therefore, the probe is often used to collect gas for accurate detection. Since the connecting pipe is connected to the mounting seat on the monitor and the probe through the end, the connecting pipe may be displaced with the movement of the probe, which may cause gas leakage and affect the accuracy of detection. Moreover, the monitor needs to be held with one hand when in use, and holding the monitor with the other hand may affect the flexibility of personnel activities and limit their activities, which is not convenient for them to record other work.

[0009] Further, the anti-skid teeth are arranged on the inner side of the limiting block, so that the friction between the limiting block and the connecting pipe is increased.
[0010] Further, the anti-skid patterns are arranged on the outer wall of the movable cylinder, so that the friction between the hand and the movable cylinder is increased, and the movable cylinder is conveniently and effectively driven.
