In order to ensure air quality, a variety of air monitoring instruments are used to monitor the air in real time under existing conditions. The current fixed gas detector probe is an integral setting rather than a detachable connection. Separating the detection probe and the shell on which the detection probe is installed will inevitably cause damage to the overall components.

[0003] Under existing conditions, connection structures that are easy to disassemble and assemble are gradually adopted. For example, a detachable high-precision digital probe disclosed in announcement number CN218099083U can be disassembled into various parts to repair and replace damaged parts when it needs to be repaired. However, the connection structure adopted is relatively simple, so that the digital probe body is composed of a front cover and a rear cover, and the front cover and the rear cover are assembled and connected by a single threaded connection. Although the disassembly and assembly operation is simple, the connection stability and sealing between the two cannot be guaranteed, so that the digital probe is very easy to loosen and separate during use.
