[0027] In a specific embodiment, as shown in Figures 3-5As shown, the storage unit 5 comprises a connecting rod 51, a storage tube 52 and a cover plate assembly 53. The storage tube 52 is cylindrical and has a rectangular cross section at the vertical side. A peach core structure 521 is arranged on one side of the rectangular cross section. The peach core structure 521 is located at the upper end of the storage tube, and the storage tube is a hollow structure. A sliding head 54 is slidably connected in the peach core structure 521, and the sliding head 54 can slide along the trajectory of the peach core structure 521. The sliding head 54 is fixed to the upper end of the connecting rod 51, and the lower end of the connecting rod 51 is hingedly connected to a fixed seat 55, which is installed on the bottom of the box body 1. The peach core structure 521 is a special polygon. When the cell cryopreservation tube 6 is not stored, the sliding head 54 falls to the bottom end of the peach core structure. A button head 522 is arranged on one side of the upper end of the storage tube 52, and the button head 522 is integrated with the storage tube 52. When the cell cryopreservation tube 6 is placed in the storage tube 52 and the button head 522 is pressed, the sliding head 54 is driven by the connecting rod 51 to slide in the left trajectory channel in the upward direction, because the slope of the left trajectory of the peach core structure 521 is smaller than that of the right trajectory, until the sliding head 54 falls into the groove at the upper end of the peach core structure 521. The cell cryopreservation tube 6 falls with the movement of the peach core structure 521, and the upper end of the cell cryopreservation tube 6 is lower than the cover plate assembly 53. The cover plate assembly 53 is installed in the box cover 2 and is sealingly installed with the box cover 2. A sealing gasket 57 is arranged at the lower end of the cover plate assembly 53, and the sealing gasket 57 is fixed to the lower side of the box cover 2.
