Novel cell cryopreservation tube protection kit

The utility model discloses a novel cell cryopreservation tube protection kit. The novel cell cryopreservation tube protection kit comprises a protection sleeve, a placement cavity, an end cover and a positioning structure, through the arrangement of the positioning structure, when a cryopreservation tube is placed in the placing cavity, the cryopreservation tube moves downwards to be inserted into the placing opening and ejects the positioning plate open, so that the positioning plate is stressed to deform to abut against the surface of the cryopreservation tube, and then the cryopreservation tube is clamped by the positioning plate; the cryopreservation tubes of different specifications can be fixed when being placed in the placing cavity, so that the cryopreservation tubes of different specifications can be placed in the placing cavity and clamped and fixed, and the situation that the small cryopreservation tubes shake and collide in the placing cavity to be broken is avoided. 本实用新型公开了一种新型细胞冻存管保护套件，包括保护套管、
