[0002] In the biomedical field, reproductive cells such as sperm, eggs, and embryos need to be cryopreserved. Currently, hospitals or research institutions generally place sample boxes containing sample tubes into liquid nitrogen tanks manually, which is not only inefficient and risky in the storage process, but also usually requires a large number of liquid nitrogen tanks, which takes up a large space and a large number of tanks, but does not achieve a high storage capacity.

[0003] The construction of a sample library requires high costs, including the need for tens of thousands of cryoboxes. Traditional cryoboxes have multiple regular arrays of round or square holes inside, which can only store a limited number of sample cryotubes and are only used for storage, not for cold preservation. They are also not easily compatible with external manipulators, and have low storage efficiency, resulting in high costs for the construction of sample libraries. Summary of the invention
