A sleeve 11 is fixedly connected to the lower end of the installation disk 7. The sleeve 11 is sleeved and rotatably connected to the outside of the connecting pipe 3. The lower end of the sleeve 11 is inserted and threadedly connected into the sleeve 12. A limiting mechanism 9 is installed on both sides of the installation disk 7; The communicating mechanism 8 includes a fixed pipe 81. The upper end of the fixed pipe 81 penetrates through the upper side wall of the connecting pipe 3 and is fixedly connected to the middle of the lower end of the installation disk 7. The sensor of the hydrogen analyzer 10 passes through the installation disk 7 and is inserted into the upper end inside the fixed pipe 81. A first sliding disk 82 is fixedly connected to the lower end of the fixed pipe 81. The first sliding disk 82 is slidably connected to the middle inside the connecting pipe 3. The upper end of the first sliding disk 82 is flush with the lower end of the rubber lining 6. A second through hole 83 is opened in the middle of the first sliding disk 82. A second sliding disk 85 is fixedly connected to the lower end of the first sliding disk 82 through a plurality of connecting plates 84. The plurality of connecting plates 84 are equidistantly arranged around the upper end of the second sliding disk 85. The number of the connecting plates 84 is the same as the number of the communicating grooves 4 and they are arranged staggeredly. The second sliding disk 85 is slidably connected to the lower end inside the connecting pipe 3; The limiting mechanism 9 includes a fixed block 91. The fixed block 91 is fixedly connected to the outer circumferential wall of the installation disk 7. A grip rod 92 is fixedly connected to the lower end of the fixed block 91. The grip rod 92 is parallel to the connecting pipe 3. The middle of the grip rod 92 is fixedly connected to the outer circumferential wall of the sleeve 11 through a connecting block 93.

Then rotate the rotating plate 96 in the reverse direction and press the rotating plate 96 against the upper end of the sleeve 12 so that the second sliding plate 85 cannot slide downward. Then the hydrogen analyzer 10 can be removed from the mounting plate 7 for overhaul. After the overhaul is completed, fix the hydrogen analyzer 10 on the mounting plate 7, pass the sensor of the hydrogen analyzer 10 through the mounting plate 7 and insert it into the fixing pipe 81.
