The box transfer plate 300 has a box taking state and a box storing state. When the box transfer plate 300 is in the box taking state, the box transfer plate 300 receives the first freezing box or the second freezing box from a storage device, and moves the first freezing box or the second freezing box above the first opening 211 or the second opening 221, and then places the first freezing box or the second freezing box on the first placing surface 212 or the second placing surface 222 by the relative vertical movement. When the box transfer plate 300 is in the box storing state, the box transfer plate 300 moves below the first opening 211 or the second opening 221, and then lifts the first freezing box or the second freezing box by the relative vertical movement, and moves the first freezing box or the second freezing box to the storage device.

[0028] Specifically, the storage device defines a storage cavity, and the storage cavity has a front opening. A cover is arranged outside the front opening, and the freezing box transfer device 10 is arranged in the cover. A shell opening is arranged above the cover.

Alternatively, the user puts the first cryogenic box and the second cryogenic box into the tray 200 through the shell opening, the tube moving mechanism moves the A and B cryogenic tubes in the first cryogenic box to the second cryogenic box, and then the box moving plate 300 sends the second cryogenic box back to the storage cavity.
