Therefore, they should not be construed as limitations on this utility model.

[0020] Examples of embodiments of this utility model Figures 1 to 5 As shown, a stool sampling cup includes a cup body 1, on which a cup lid 2 is provided. Preferably, the cup lid 2 is threadedly connected to the top of the cup body 1 and seals the cup body 1. A sleeve 20 with a threaded inner wall is provided on the inner bottom surface of the cup lid 2. Preferably, the sleeve 20 is integrally formed with the cup lid 2. A threaded rod 3 is threadedly connected to the inner side of the sleeve 20. A sampling element 4 is provided at one end of the threaded rod 3 away from the inner bottom surface of the cup lid 2, that is, the sampling element 4 is connected to the bottom end of the threaded rod 3. A limiting blind hole 5 coaxial with the threaded rod 3 is provided at the other end of the threaded rod 3 away from the sampling element 4, that is, the limiting blind hole 5 is located at the top of the threaded rod 3. The limiting blind hole 5 also... Extending vertically, a limiting rod 52, which drives the threaded rod 3 to rotate, is provided inside the limiting blind hole 5. An extension rod 6 is provided at the end of the limiting rod 52 away from the sampling piece 4, that is, the extension rod 6 is located at the top of the limiting rod 52. The extension rod 6 passes through the top surface of the cup lid 2 and is rotatably connected to the cup lid 2. The cup lid 2 is provided with a cup lid through hole for the extension rod 6 to pass through. Preferably, a bearing is provided between the cup lid through hole and the extension rod 6. The outer ring of the bearing is installed in the cup lid through hole, and the inner ring of the bearing is sleeved on the extension rod 6. The extension rod 6 is provided with an anti-rotation mechanism to limit the rotation of the extension rod 6 after it has rotated relative to the cup lid 2.

[0021] Remove the cup lid 2 from the cup body 1, and then let the cup lid 2 and the extension rod 6 rotate relative to each other. The extension rod 6 drives the threaded rod 3 to rotate relative to the sleeve 20 through the limiting rod 52. At this time, the threaded rod 3 slides relative to the limiting rod 52. The threaded rod 3 extends out of the sleeve 20 or retracts into the sleeve 20, which makes it convenient to adjust the length of the sampling piece 4. After adjusting the length of the sampling piece 4 by rotating the cup lid 2 or the extension rod 6, the anti-rotation mechanism restricts the extension rod 6 from rotating relative to the cup lid 2, thereby maintaining the length of the sampling piece 4, which is very convenient.
