[0029] The CO gas sensor 5 is placed on the top of the sealing cover 9, and then the worker holds the rotating handle and rotates, so that the threaded rod 45 rotates, and the clamping plate 43 moves towards the CO gas sensor 5 with the rotation of the threaded rod 45, until the clamping plate 43 is attached to the four sides of the CO gas sensor 5, to achieve the positioning of the clamping plate 43 to the CO gas sensor 5, which can avoid the shaking of the CO gas sensor 5 during use, thereby improving the monitoring accuracy of the CO gas sensor 5 to the CO gas inside the sampling pipe 1 and the coal powder pipeline body 2. Then the worker reversely rotates the rotating handle, that is, the clamping plate 43 is moved away from one side of the CO gas sensor 5, so as to complete the replacement and disassembly of the CO gas sensor 5.
