[0002] A combustible gas detector is a device for detecting the concentration of combustible gases, and is commonly used in inspection work in chemical industries, fire fighting and other occasions. Traditional combustible gas detectors are composed of components such as a detector body, an alarm, and a suction pipe. By aligning the suction pipe with the detection site, the concentration of combustible gases can be measured, and an alarm will sound when the concentration of combustible gases reaches the set value. Although such traditional combustible gas detectors can measure the concentration of combustible gases, since the detector needs to be held by hand, when the user is measuring, it is inconvenient for the user to record data in a record book, and when the detection site is behind obstacles such as fences, it is difficult for the user to directly extend the detector to the detection site, which reduces the flexibility of the device to a certain extent and brings inconvenience to the user.
