[0020] The following is a further detailed description of the sampler for collecting diarrhea stool samples of the present invention in conjunction with the accompanying drawings.

[0021] In conjunction with the accompanying drawings, a sampler for collecting diarrhea stool samples includes a box body 1, a fixed inner ring 2, a movable inner ring 5, a box cover 8, and a pipette 10. The box body 1 is a cylindrical structure with an open top. The inner wall of the box body 1 is provided with a fixed inner ring 2 that is fixedly connected. The fixed inner ring 2 is circumferentially provided with a plurality of mounting grooves 3. Each mounting groove 3 is provided with a fixed spring 4. The other end of the spring 4 is fixedly connected to the lower surface of the movable inner ring 5. The inner wall of the box body 1 is provided with a No. 1 thread 7;

[0022] The side wall of the box cover 8 is provided with a second thread 9, and the box body 1 and the box cover 8 form a threaded connection structure through the first thread 7 and the second thread 9;

[0023] The box cover 8 is provided with a fixed pipette 10 , a rubber ball 11 is installed on the top of the pipette 10 , a pipette port 13 is provided at the bottom of the pipette 10 , and a fixed sampling shovel 12 is also provided on the body of the pipette 10 .

[0024] As a preferred implementation scheme of this embodiment, a plurality of connecting rods 6 corresponding to the installation grooves 3 are circumferentially provided on the lower surface of the movable inner ring 5 , and a spring 4 is sleeved on the outer wall of the connecting rod 6 .

[0025] As a preferred implementation scheme of this embodiment, the starting end of the No. 1 thread 7 is higher than the top of the fixed inner ring 2 in the vertical direction; the ending end of the No. 1 thread 7 is lower than the top of the movable inner ring 5 in the vertical direction.

[0026] As a preferred implementation of this embodiment, the pipette 10 is made of transparent plastic.

[0027] As a preferred implementation of this embodiment, a scale line 14 is provided on the pipette 10 .

[0028] In the specific implementation of the present invention, when the device is used, the box cover 8 is opened, the rubber ball 11 is squeezed to generate suction, and the diarrhea stool sample is sucked using the suction port 13 at the bottom of the pipette 10. For solid samples, the sampling shovel 12 can also be used to scrape;

[0029] After the sampling is completed, hold the box cover 8 and place it into the box body 1, and gently press down the box cover 8 so that the movable inner ring 5 is pressurized by the spring 4 and moves downward, exposing the No. 1 thread 7. At this time, turn the box cover 8, and through the threaded connection between the No. 1 thread 7 and the No. 2 thread 9, firmly tighten the box cover 8 on the box body 1. The sample is stably fixed in the box body 1 to prevent leakage and contamination.

[0030] When taking out a sample for testing, first rotate the box cover 8 in the opposite direction to release the threaded connection between it and the box body 1. Under the action of the spring 4, the movable inner ring 5 will bounce upward, and then lift the box cover 8 upward. At this time, the box cover 8 can be easily removed, and then the sample can be taken out for testing;

[0031] The transparent plastic pipette 10 and the scale lines 14 can help observe and measure the sample volume.

[0032] The above description of the present invention and its embodiments is non-limiting. The drawings show only one embodiment of the present invention, and the actual structure is not limited thereto. In short, if a person skilled in the art is inspired by the above, and does not deviate from the purpose of the present invention, without inventive design, a structure and embodiment similar to the technical solution should fall within the scope of protection of the present invention.
