[0036] The core pipe body 5 is fixedly arranged at the upper opening of the extraction test tube body 1, and the upper portion of the core pipe body 5 is equipped with upper ring body 10;

[0037] The annular antiskid ring 6 abuts against the inner wall of the upper opening of the extraction test tube body 1, and the lower side of the upper ring body 10 abuts against the upper wall of the upper opening of the extraction test tube body 1.

[0038] Preparation stage:

[0039] First, ensure that the extraction test tube body 1 has been loaded with detection reagent. The section of the extraction test tube body 1 presents circle, and the upper portion thereof is equipped with cover 2, and the section of the cover 2 is also circle, and the edge of the cover 2 is equipped with friction lines 3, which helps to increase the friction when opening and closing the cover 2 so as to operate.

[0040] The sample sampling rod destroying mechanism 4 is in a ready state. Among them, the core tube body 5 in the sample sampling rod destroying mechanism 4 is penetrated at the upper and lower ends, the outer wall is provided with an annular groove, and an annular anti-skid ring 6 is embedded in the annular groove. The annular anti-skid ring 6 is made of rubber and the outer wall protrudes out of the annular groove. The inner wall of the core tube body 5 is fixed with a sample sampling rod destroying frame 7, which is a two-stage bending rod with an acute angle. The two ends of the sample sampling rod destroying frame 7 are fixedly connected with the inner wall of the core tube body 5 and are integrally formed. The upper inner side edge of the core tube body 5 is provided with a sample sampling rod destroying support part 8, which contains a plurality of uniformly arranged destroying grooves 9. The sample sampling rod destroying support part 8 is located on the side where the opening of the sample sampling rod destroying frame 7 faces. At the same time, the core tube body 5 is fixedly arranged at the upper opening of the extraction test tube body 1. The upper part of the core tube body 5 is provided with an upper ring body 10. The annular anti-skid ring 6 abuts against the inner wall of the upper opening of the extraction test tube body 1, and the lower side of the upper ring body 10 abuts against the upper wall of the upper opening of the extraction test tube body 1.

[0041] Sample putting stage:

[0042] The user holds the extraction test tube body 1 with his hand, uses the friction lines 3 at the edge of the cover body 2, and opens the cover body 2 on the extraction test tube body 1 by rotating or pulling and the like.

[0043] Then, the sample sampling rod after sampling is taken, the sampling cotton swab part of the sample sampling rod is aligned with the upper opening of the core tube body 5, and the sampling cotton swab part is carefully inserted through the core tube body 5. Since the core tube body 5 is penetrated at the upper and lower ends, the sampling cotton swab part can smoothly pass through. In the process of passing through the core tube body 5, the sampling cotton swab part also needs to pass through the sample sampling rod destroying frame 7 on the core tube body 5. Here, attention should be paid to make the sampling cotton swab part pass along the space of the destroying frame 7, until the sampling cotton swab part of the sample sampling rod after sampling extends into the extraction test tube body 1.

[0044] Sample sampling rod destroying stage:

[0045] Next, the part of the sample sampling rod outside the extraction test tube body 1 is held with the hand, and the sample sampling rod is bent downward. In the bending process, it is ensured that the lower part of the sample sampling rod is accurately located at the bending part of the sample sampling rod destroying frame 7, and the sample sampling rod abuts against the destroying groove 9 on the sample sampling rod destroying support part 8. Since the included angle of the sample sampling rod destroying frame 7 is an acute angle, such a structure design can realize the fracture of the sample sampling rod at the destroying groove 9 when a certain bending force is applied.

[0046] Reaction stage:

[0047] When the sample sampling rod is broken, the sampling cotton swab part of the sampling rod is completely located in the extraction test tube body 1. The sampling cotton swab part will react with the detection reagent contained in the extraction test tube body 1.

[0048] Finishing stage:

[0049] After the reaction is completed or the operation according to the detection process is completed, the extraction test tube body 1 is held by hand again, the cover body 2 is covered back to the extraction test tube body 1, and it is ensured that the extraction test tube body 1 is in a closed state, so as to facilitate subsequent processing of the sample or observation of the detection result and the like.

[0050] Destroying the sample sampling rod: the design of the sample sampling rod destruction mechanism 4 is beneficial to accurate processing of the sample. The structure cooperation of the sample sampling rod destruction frame 7 and the sample sampling rod destruction support part 8 in the core tube body 5 can accurately realize the breaking of the sample sampling rod. The sample sampling rod destruction frame 7 is a two-stage bending rod with an acute angle, and cooperates with a plurality of uniformly arranged destruction grooves 9 on the sample sampling rod destruction support part 8, so as to ensure that the sampling rod is broken at a specific position, and the sampling cotton swab part accurately falls into the extraction test tube body 1 and fully reacts with the detection reagent, thereby improving the accuracy of sample processing.

[0051] The design of the sample sampling rod destruction mechanism 4 is ingenious. The cooperation of the sample sampling rod destruction frame 7 and the sample sampling rod destruction support part 8 in the core tube body 5 can accurately realize the breaking of the sample sampling rod. This design is beneficial to accurately leaving the sampled sample in the extraction test tube body 1 to fully react with the detection reagent, thereby improving the accuracy of detection.

[0052] Safety and reliability: the annular anti-skid ring 6 is made of rubber material, which not only ensures the stable connection of the core tube body 5 on the extraction test tube body 1, but also is relatively soft and is not easy to cause damage to the test tube and the like during operation, thereby improving the safety and reliability of the whole device.
