[0016] Compared with the prior art, the present invention has the following beneficial effects:
[0017] 1. The present invention arranges a convenient sampling mechanism structure in the sampling reagent tube, and the test tube top cover cooperates with the thread and the sealing structure to realize installation on the top of the sampling reagent tube and sealing. A functional sampling mechanism is arranged in the convenient sampling mechanism. By removing the convenient sampling mechanism and holding the test tube top cover, during the sampling process, the bottom sampling half box is driven to move downward by pressing the pressing top block, and the sampling half boxes on both sides are driven to rotate outward under the pulling effect of the transmission line to achieve the opening effect, and the sampling half boxes are aligned with the sampling feces at the appropriate position and the pressing top block is released at the same time, so that the sampling half boxes in the opened state can be merged and a certain amount of samples can be clamped and placed in the space formed by the two sampling half boxes. Through the transmission of the functional sampling mechanism and the structural design of the sampling half box part, even non-professional sampling personnel can realize convenient and efficient sampling, avoiding the problems of the conventional shovel-type sampling end that is easy to have the sampling amount cannot be guaranteed and the sample falls during the sampling process;
[0018] 2. The present invention is provided with a functional structure at the end of the convenient sampling mechanism to facilitate medical staff to efficiently dilute the sample to prepare a sample solvent. By pressing the sealing plug at the top block end and the setting of the sample adding notch in the sampling rod, the medical staff only needs to insert the dilution reagent through the needle into the sealing plug through the sample adding notch to inject it into the sampling reagent tube without transferring the fecal sample, thereby improving efficiency and avoiding problems such as sample loss and bacterial leakage;
[0019] 3. The present invention can facilitate the preparation of sample solvents through the transmission structure of the functional sampling mechanism and the design of the sampling half-box structure. After the reagent is injected into the sampling reagent tube, the feces sample is placed inside through the two combined sampling half-boxes. The reagent can enter the interior of the sampling half-box through the penetration groove and the liquid inlet groove by shaking, and part of the feces is dissolved in the reagent and overflows through the penetration groove and the liquid inlet groove under the effect of shaking. The raised bars can reduce the contact area between the sampled feces and the inner wall of the sampling half-box to ensure the penetration of the reagent. At the same time, the dissolution and exudation and shaking action can accelerate the dispersion and dissolution effect of the feces, so as to avoid the feces being affected by the state and adhering to the wall, thereby affecting the shaking effect and slowing down the dispersion and dissolution efficiency.
[0020] 4. The present invention can realize efficient extraction of sample solvent for testing through the functional sampling mechanism structure and the separation sampling mechanism. After shaking, the sampling half box is slightly pressed to open and not contact the pressing slide plate, so that the hard blocks that cannot be dissolved in the feces are scattered outside the sampling half box after opening. Through shaking and adjustment, all the hard blocks are placed outside the range of the sampling half box, and the pressing top block is pressed to the bottom to open the sampling half box to the maximum range. At the same time, the sampling half box is squeezed and contacted with the pressing slide plate during the process, so that the top of the sampling tube and the sealing baffle are lifted up, so that the sample solvent can pass through. The solvent is dripped into the detection module through the sampling tube to realize efficient detection without transfer, and the sampling half box is opened to the maximum range and together with the side baffles on both sides to form a solvent filtration space, so that there are no hard lumps in the space formed by the opened sampling half box and the side baffles to avoid clogging the sampling tube and affecting the reagent detection problem. At the same time, the sample solvent all flows into the lower space of the partition sampling mechanism under the guidance of the sampling tube. Subsequently, the sample solvent in the lower space of the partition sampling mechanism can be taken out by inserting a needle into the rubber stopper for other tests, thereby achieving efficient and convenient sampling and detection functions.

[0049] The specific use steps of the present invention are as follows:
[0050] A convenient sampling mechanism 15 structure is arranged in the sampling reagent tube 11, and the test tube top cover 21 is matched with the thread and the sealing structure to realize installation on the top of the sampling reagent tube 11 and sealing. A functional sampling mechanism 25 is arranged in the convenient sampling mechanism 15. By removing the convenient sampling mechanism 15 and holding the test tube top cover 21, during the sampling process, by pressing the pressing top block 34, the bottom sampling half box 30 is driven to move downward, and the sampling half boxes 30 on both sides are driven to rotate outward under the pulling effect of the transmission line 29 to achieve the opening effect, and the pressing top block 34 is released while the sampling half boxes 30 in the opened state are aligned with the sampling feces, so that a certain amount of sample can be clamped and placed in the space formed by the two sampling half boxes 30. Through the transmission of the functional sampling mechanism 25 and the structural design of the sampling half boxes 30, even non-professional sampling personnel can realize convenient and efficient sampling, avoiding the problems of the conventional shovel-type sampling end that the sampling amount cannot be guaranteed and the sample falls during the sampling process;
[0051] After the sampling is completed, the convenient sampling mechanism 15 is rotatably sealed and installed on the sampling reagent tube 11 and can be handed over to the medical staff. A functional structure is provided at the end of the convenient sampling mechanism 15 to facilitate the medical staff to efficiently dilute the sample to make a sample solvent. By pressing the sealing plug 38 at the end of the top block 34 and the setting of the sample adding notch 36 in the sampling rod 35, the medical staff only needs to insert the dilution reagent through the needle into the sealing plug 38 through the sample adding notch 36 to inject it into the sampling reagent tube 11 without transferring the fecal sample, thereby improving efficiency and avoiding problems such as sample loss and bacterial leakage;
[0052] The transmission structure of the functional sampling mechanism 25 and the structural design of the sampling half box 30 can facilitate the preparation of the sample solvent. After the reagent is injected into the sampling reagent tube 11, the feces sample is placed inside through the two combined sampling half boxes 30. By shaking, the reagent can enter the interior of the sampling half box 30 through the penetration groove 31 and the liquid inlet groove 42, and under the effect of shaking, part of the feces is dissolved in the reagent and overflows through the penetration groove 31 and the liquid inlet groove 42. The provision of the raised bar 40 can reduce the contact area between the sampled feces and the inner wall of the sampling half box 30 to ensure the penetration of the reagent. At the same time, the dissolution and exudation and shaking action can accelerate the dispersion and dissolution effect of the feces, and avoid the feces being affected by the state and sticking to the wall, thereby affecting the shaking effect and slowing down the dispersion and dissolution efficiency.
[0053] The functional sampling mechanism 25 structure cooperates with the separation sampling mechanism 20 to realize efficient extraction of sample solvent for testing. After shaking, the sampling half box 30 is slightly pressed to open and not contact the pressing slide plate 45, so that the hard lumps in the feces are scattered outside the sampling half box 30 after opening. By shaking and adjusting, all the hard lumps are placed outside the sampling half box 30, and the pressing top block 34 is pressed to the bottom to open the sampling half box 30 to the maximum range. At the same time, the sampling half box 30 is squeezed and contacted with the pressing slide plate 45 during the process, so that the top of the sampling tube 52 is lifted up by the sealing baffle 49, so that the sample solvent can pass through the sampling half box 30. The sample tube 52 is dripped into the solvent detection module 55 to realize efficient detection without transfer, and the sampling half box 30 is opened to the maximum range and together with the side baffles 46 on both sides to form a solvent filtering space, so that there is no hard agglomerate in the space formed by the opened sampling half box 30 and the side baffles 46 to avoid clogging the sampling tube 52 and affecting the reagent detection problem. At the same time, the sample solvent flows into the lower space of the partition sampling mechanism 20 under the guidance of the sampling tube 52. Subsequently, the sample solvent in the lower space of the partition sampling mechanism 20 can be taken out by inserting a needle into the rubber plug part 18 for other detections, thereby achieving efficient and convenient sampling and detection functions.
