[0002] Stem cells are generally cryopreserved by placing cryotubes into cryoboxes, which are then placed on cryoracks and then placed in liquid nitrogen tanks for storage. However, the following problems exist in the current use of cryoboxes: they have a small range of applicability and cannot hold cryotubes of different diameters; after the cryorack is taken out as a whole in an ultra-low temperature environment, several cryotubes are densely distributed in a matrix with the same top height, making it inconvenient to take out one of the cryotubes; the insertion hole of the cryotube that the cryobox is adapted to is slightly larger than the outer diameter of the cryotube, and there is a risk of the cryotube slipping out of the cryobox during operation.

[0003] Therefore how to solve the above-mentioned technical problems just becomes the problem that the utility model faces. Utility Model Content
