Two slide grooves 603 are provided inside the connecting ring 2. The separated surfaces of the two sliders 602 are fixedly connected with the spring 604. The bottom of the fixed ring 3 is fixedly connected with two fixed rods 605.
[0022] The sealing structure 7 includes a protective cover 701, a port plug 702, an internal thread 703 and an external thread 704.

[0023] In the case implementation, a capillary needle is arranged on the outside of the sampling end 5 , and the sampling end 5 collects samples by capillary action. The dripping end 4 is matched with the port plug 702 , and the internal thread 703 is matched with the external thread 704 .
[0024] In the case implementation, the inner diameters of the fixing ring 3 and the connecting ring 2 are both provided with sealing rings to enhance the sealing of the reaction bottle 1 and prevent liquid from splashing out.
[0025] In the case implementation, the pre-reaction mixture after shaking can open the protective cover 701, then the whole sampling device is inverted, and finally dripped out through the dripping end 4 and then tested with the reagent.
[0026] When implementing, follow these steps:
[0027] 1) First, the sampling end 5 collects the sample and drops it into the interior of the reaction bottle 1;
[0028] 2) Then the two moving rods 601 are moved toward the separated surfaces, the spring 604 contracts, the connecting ring 2 is pressed against the fixing ring 3, the fixing rod 605 enters the fixing groove 9, the two moving rods 601 are loosened, and the deformation force of the spring 604 drives the two moving rods 601 to pass through the fixing groove 9 and the limiting groove 10, thereby fixing the connecting ring 2 and the fixing ring 3;
