[0034] Initial state preparation:

[0035] The sampling shell 7 is located in the excrement sampling cavity 3, and the sampling shell 7 is circular in the top view and penetrable on both sides, and the lower edge and the upper edge of the sampling shell 7 are in sliding fit with the outer wall of the excrement sampling cavity 3. The sliding rod body 8 in the upper middle part of the sampling shell 7 penetrates the middle through hole 6 and the internally threaded hole body 4 and extends to the upper side of the internally threaded hole body 4, and the top of the sliding rod body 8 is provided with a pressing plate 9. The lower part of the pressing plate 9 is provided with a spring 10, and the spring 10 is sleeved on the sliding rod body 8 and abuts against the middle partition plate 5 in the lower part.

[0036] The internally threaded hole body 4 is provided with an externally threaded pipe body 11, and the externally threaded pipe body 11 is in threaded fit with the internally threaded hole body 4. The upper part of the externally threaded pipe body 11 is provided with an auxiliary rotating ring body 12. In the initial state, the sampling shell 7 is completely located in the excrement sampling cavity 3, and the auxiliary rotating ring body 12 in the upper part of the externally threaded pipe body 11 abuts against the lower part of the pressing plate 9, so that the downward movement of the pressing plate 9, the sliding rod body 8 and the sampling shell 7 is limited, thereby ensuring that the sampling shell 7 does not separate from the excrement sampling cavity 3 and ensuring that the sampling shell 7 is in a clean and sanitary state.

[0037] Sampling operation process:

[0038] When the excrement sampling is to be performed, the auxiliary rotating ring body 12 in the upper part of the externally threaded pipe body 11 is first rotated by hand. Since the externally threaded pipe body 11 is in threaded fit with the internally threaded hole body 4, the rotation of the auxiliary rotating ring body 12 will cause the externally threaded pipe body 11 to gradually move to the inside, i.e. to the inside of the internally threaded hole body 4, until the externally threaded pipe body 11 and the related overall part thereof are completely in the internally threaded hole body 4, at which time the limitation of the downward movement of the pressing plate 9 by the auxiliary rotating ring body 12 is removed.

[0039] Then, the user abuts the lower side of the pressing ear 2 with the fingers to provide a stable supporting force, and then presses the pressing plate 9. Since the pressing plate 9 is subjected to the downward pressure, the sliding rod body 8 will move downward, and the spring 10 sleeved on the sliding rod body 8 will be compressed. In this process, since the lower edge and the upper edge of the sampling shell 7 are in sliding fit with the outer wall of the excrement sampling cavity 3, the sampling shell 7 will slide downward along the outer wall of the excrement sampling cavity 3 under the action of the pressure and gradually extend out of the excrement sampling cavity 3.

[0040] When the sampling shell 7 extends to a sufficient length, the sampling shell 7 can be used to perform the sampling operation on the excrement.

[0041] Sampling operation process:

[0042] After the sampling is completed, the pressing plate 9 is loosened. Due to the recovery of the previously compressed spring 10, the spring 10 releases the elastic potential energy and generates an upward elastic force. Under the action of this elastic force, the pressing plate 9 moves upward, driving the sliding rod body 8 to move upward, so that the sampling shell 7 slides upward along the outer wall of the feces sampling cavity 3 until the sampling shell 7 is completely located in the feces sampling cavity 3.

[0043] Finally, the auxiliary rotating ring body 12 at the upper part of the outer threaded pipe body 11 is rotated again by hand, and the outer threaded pipe body 11 moves upward until the auxiliary rotating ring body 12 at the upper part of the outer threaded pipe body 11 again abuts against the lower part of the pressing plate 9. In this way, it is ensured that the feces sample in the sampling shell 7 will not flow out and will not be contaminated by the outside world, facilitating subsequent detection and other operations on the feces sample.

[0044] High operational convenience: the user only needs to perform simple operations such as rotating the auxiliary rotating ring body 12 on the outer threaded pipe body 11 and pressing the pressing plate 9, so as to easily complete the preparation of the sampling device and the collection of the feces sample. The entire process does not require complex tools or professional skills, even non-professionals can quickly get started, effectively improving the sampling efficiency, especially suitable for hospitals and other places that need to perform a large number of feces sampling and detection, reducing the operation time and energy consumption of medical staff.

[0045] Good sample integrity: the design of the sampling shell 7 and its sliding fitting mechanism with the feces sampling cavity 3 enable stable acquisition of the feces sample during sampling, reducing sample spilling and loss. At the same time, the elastic action of the spring 10 can make the sampling shell 7 smoothly retract into the feces sampling cavity 3 after sampling, and remain closed under the abutting action of the auxiliary rotating ring body 12, ensuring the integrity of the sample during transportation and storage, and being conducive to the accuracy and reliability of subsequent detection results, providing high-quality sample basis for the diagnosis of digestive diseases.

[0046] Good hygiene: in the initial state, the sampling shell 7 is completely located in the feces sampling cavity 3, and the auxiliary rotating ring body 12 of the outer threaded pipe body 11 abuts against the pressing plate 9, effectively preventing external pollutants from entering the sampling shell 7 and ensuring that the inside is always clean and hygienic. After the sampling is completed, the sampling shell 7 can also be sealed by the cooperation of the outer threaded pipe body 11 and the auxiliary rotating ring body 12, avoiding leakage and pollution of the surrounding environment by the feces sample, maximizing the hygiene and safety of the sampling process, reducing the risk of cross infection, and meeting the strict requirements of medical detection on hygiene standards.

[0047] Compact and reliable structure: the structure design of the whole device is compact and reasonable, the core shell 1, the sampling shell 7, the internal thread hole body 4, the external thread pipe body 11 and other components cooperate with each other to form a stable and efficient sampling system. The connection and movement mode between the components are carefully designed, such as the through cooperation of the sliding rod body 8 with the middle through hole 6 and the internal thread hole body 4, and the elastic buffering and resetting action of the spring 10 in them, so that the device is not prone to failure during multiple uses, has high reliability and durability, reduces the equipment maintenance cost and replacement frequency, and improves the utilization efficiency of medical resources.

[0048] The above describes the utility model and its implementation mode, which is not limited, and the drawings shown are only one of the embodiments of the utility model, and the actual structure is not limited thereto. In summary, if a person skilled in the art is inspired, without departing from the creative purpose of the utility model, similar structure modes and embodiments are not creatively designed, which should belong to the protection scope of the utility model.
