[0020] The inner wall of the instrument platform 12 is threadedly connected with two groups of limit rods 16, and the two groups of limit rods 16 are distributed in a rectangular shape on the instrument platform 12. The limit rods 16 can limit the detection instrument to prevent the detection instrument from falling from the instrument platform 12. The outer surface of the support shaft 14 is threadedly connected with two fastening nuts 13. The side surfaces of the two fastening nuts 13 that are close to each other are respectively in contact with the upper surface and the bottom surface of the rotating plate 11. The fastening nuts 13 can fasten the support shaft 14, which is beneficial to reduce the loosening of the support shaft 14. Two groups of disassembly nails 7 are provided at the bottom of the telescopic rod 8. The outer surface of each group of disassembly nails 7 is threadedly connected to the inner wall of the mounting plate 2. The disassembly nails 7 can connect the telescopic rod 8 and the mounting plate 2 to achieve the purpose of fixing the telescopic rod 8.

[0021] A base frame 3 is fixedly installed on the bottom surface of the cabinet 1, and two sets of adjustable feet 5 are threadedly connected to the bottom inner wall of the base frame 3. Through the base frame 3 and the adjustable feet 5, the base frame 3 is used to support the cabinet 1, and the adjustable feet 5 can adjust the height of the base frame 3 to a certain extent. A baffle 4 is fixedly installed on the inner wall of the cabinet 1, and a closed door 6 is slidably connected to the inside of the cabinet 1. Through the baffle 4, ventilation can be allowed at the baffle 4, and airflow can be circulated when airflow detection is performed, and the closed door 6 is the closed part of the cabinet 1.

[0022] The working principle of the utility model is: when in use, the cabinet 1 mainly uses the fan to suck the air in the cabinet 1 outward, so that the cabinet 1 maintains a negative pressure state, thereby protecting the experimenter. At the same time, it protects the sample through the vertical airflow from top to bottom. This airflow is the clean air after being filtered by the high-efficiency filter. Finally, the air also needs to be filtered by the high-efficiency filter before being discharged into the atmosphere to protect the environment. When testing the high-efficiency filter, a special testing instrument will be used. In order to facilitate the testing of the testing instrument in the cabinet 1, the testing instrument can be placed on the instrument table 12. The testing instrument is limited by the limiting rod 16 to prevent it from falling. The height of the testing instrument can be changed according to the adjustment of the telescopic rod 8, and its detection position can be changed. The height of the testing instrument does not need to be changed by hand. After the detection is completed, the instrument table 12 can be rotated, and the testing instrument can be taken out of the cabinet 1 through the rotation of the rotating plate 11. The detection height of the testing instrument can be changed according to specific needs, which is convenient for the use of the testing instrument.
