[0003] Since there may be slight differences in water quality at different heights, in order to make the data more accurate, a stratified sampling method is generally adopted so that the data obtained is more real and reliable.

[0004] For example, patent number CN202323269698.0 is a water quality stratified sampler, which can divide the extraction box into multiple sampling cavities through multiple partitions, and cooperate with the pull rope, limit ball, sealing cover, second fixed seat, and damping plate. When sampling the water body, as the operating handle controls the depth of the extraction box in the water body, different sealing covers can be operated to unfold, and water samples of different depths can be collected into different cavities in the extraction box.

[0005] During the operation of the specific embodiment, the inventors found the following defects:

[0006] Although the water stratification sampler represented by the above patent can be used for different layers of water, its overall length and sampling cavity are fixed and cannot be adjusted according to the depth of the water body. If it is set longer, it is not easy to carry, and if it is set shorter, it cannot sample the bottom of the deeper water body.

[0007] It should be noted that the above content belongs to the technical knowledge scope of the inventor. Since the technical content in this field is vast and too complicated, the above content of this application does not necessarily constitute prior art. Utility Model Content
