During the experiment, the test kit 12 is inserted into the middle of the mounting cylinder 10, and a constant temperature state can be ensured during the experiment, thereby ensuring the accuracy of the experiment. The test kit 12 adopts a secondary sealing treatment, and the mounting cylinders are independent of each other. During the experiment, there will be no interference between the test kits, ensuring the accuracy of the experiment.

[0026] The fixing buckle 11 is of an arc-shaped structure, and there are multiple fixing buckles 11. The distance between adjacent two fixing buckles 11 is the same. The fixing groove 16 is of an L-shaped structure. One end of the fixing groove 16 is in the middle of the height head, and the other end of the fixing groove 16 is on the surface of the fixing head 13. When the test kit 12 is inserted into the mounting cylinder 10, the fixing buckle 11 and the fixing groove 16 are clamped. The insulating cylinder 18 is of a conical structure and is made of a heat-insulating material. The test kit 12 is of a cylindrical structure. The top of the test kit 12 is located inside the insulating cylinder 18. A sealing ring 19 is sleeved in the middle of the test kit 12. The sealing ring 19 is in interference fit with the mounting cylinder 10. The bottom of the test kit 12 is pressed against the extrusion head 17. When the test kit 12 and the mounting cylinder 10 are inserted together, the sealing ring 19 can ensure the sealing performance. When the test kit 12 is inserted to the bottom, the fixing buckle 11 and the fixing groove 16 are inserted into each other. At this time, the fixing head 13 is rotated to clamp the fixing buckle 11 and the fixing groove 16 together, so that the test kit 12 is fixedly connected inside the mounting cylinder 10.

[0027] The lower end of the vent head 24 is a conical structure. The sealing piece ring 22 is a flexible rubber structure and is in a funnel shape. The axes of the vent head 24 and the sealing piece ring 22 are on the same straight line. When the reagent kit 12 is inserted into the installation cylinder 10, the vent head 24 is inserted into the middle of the sealing piece. The lower end of the vent head 24 is provided with an air inlet 25, and both sides of the vent head 24 are provided with air outlets 26. The air inlet 25 and the air outlets 26 are communicated.

The lower end of the deformation piece 27 is a vertical structure. The lower end of the deformation piece 27 is inserted into the sealing cylinder 20. When the reagent kit 12 is installed, the bottom of the reagent kit 12 extrudes the extrusion head 17, and the extrusion head 17 pushes the vent head 24 to move, so that the vent head 24 is inserted into the middle of the sealing piece ring 22, and thus the air inlet 25 is moved to the lower end of the sealing piece ring 22. The hot air at the lower end of the sealing piece ring 22 reaches the air outlet 26 through the air inlet 25 and enters the isolation cylinder 18, so as to heat the inside of the isolation cylinder 18 and ensure that the inside of the isolation cylinder 18 is in a constant temperature state.

[0028] When the reagent kit 12 is not inserted into the installation cylinder 10, the heat conducting piece 31 can conduct the heat inside the heating cylinder 9, so that the heat accumulates between the sealing piece ring 22 and the heat conducting piece 31. The isolation cylinder 18 can isolate the heat to avoid unnecessary waste caused by heat dissipation. When the reagent kit 12 is inserted, the bottom of the reagent kit 12 extrudes the extrusion head 17, and the vent head 24 is inserted into the middle of the sealing piece ring 22, so that the heat accumulated between the sealing piece ring 22 and the heat conducting piece 31 is conducted into the isolation cylinder 18 to heat the reagent kit and ensure the accuracy of the detection value.
