[0002] Accurate detection of combustible gas is crucial in many scenarios such as industrial production, chemical storage, and daily life. However, traditional wall-mounted combustible gas detectors have many problems during installation and use. In terms of installation, the previous detector fixing method is often complicated and cumbersome, requiring multiple processes and a long time to complete the installation. This not only consumes a lot of manpower costs, but also may cause the detector to be not firmly fixed due to improper installation, increasing safety hazards during use. Moreover, when the detector needs to be cleaned and repaired, the removal process is also very troublesome, which brings great inconvenience to maintenance work. In terms of detection height adjustment, the height adjustment mechanism of traditional detectors is not flexible and convenient enough, and it is difficult to meet the needs of air detection at different heights. In order to achieve the ideal detection effect, it is often necessary to disassemble and adjust the height multiple times, which is not only time-consuming and labor-intensive, but may also cause damage to the detector during the disassembly and assembly process, affecting its service life.

The outer wall of the sliding ring 26 contacts the outer wall of the fixing jaw 23. The fixed jaw 23 can be stretched outward by moving the inclined surface of the sliding ring 26 along the inclined surface of the fixing jaw 23.

[0023] The lifting device 3 includes a lifting slider 31, which has a slot. The inner wall of the lifting slider 31 is slidably connected to a lifting plate 32. The lifting slider 31 slides up and down along the outer wall of the lifting plate 32. The top of the lifting slider 31 is symmetrically fixedly connected to a fixing column 33. A torsion spring 34 is provided on the outside of the fixing column 33. A positioning clamp 35 is fixedly connected to the top of the torsion spring 34.
