In terms of production effect, the sedimentation type is better than the membrane type because it can retain the inherent three-dimensional structure of cells and is more conducive to clinical diagnosis.

[0003] The existing sample pretreatment work of cytopathology based on sedimentation staining is still done manually, by manually placing the sample bottle into an oscillating mixer for processing and then manually clamping and opening the lid. This sample mixing method is both inefficient and not conducive to the automation of sample pretreatment. Summary of the invention

[0004] The utility model aims to provide a sample mixing device, which can automatically complete sample mixing, automatic clamping and capping, thereby improving the efficiency of sample pre-treatment.

[0025] The clamping jaw comprises a first clamping portion and a second clamping portion. When the clamping jaw moves, the minimum spacing of the first clamping portion is greater than the minimum spacing of the second clamping portion. The first clamping portion with a larger spacing can be used to clamp the bottle body portion of the sample bottle with a larger diameter, thereby completing the clamping and fixing of the bottle body portion of the sample bottle.
