The docking module for a cryopreservation box of claim 1, wherein the accommodating mechanism comprises an accommodating frame and a guide protrusion, the guide protrusion is arranged on the inner side wall of the accommodating frame, and the second end of the chain is fixed in the accommodating frame; the chain link of the chain comprises a first face and a second face which are opposite, the first face can be in fit connection with the chain wheel, and the second face comprises a groove which can slide along the guide protrusion.

3. The docking module of claim 2, wherein the guide protrusion comprises a first guide block and a second guide block, and the first guide block and the second guide block are respectively mounted on two opposite inner sidewalls of the accommodating frame; when the driving mechanism drives the chain wheel to rotate, the grooves of the partial chain links of the chain can sequentially slide through the first guide block and the second guide block.

4. The cryopreservation cartridge docking module of claim 3, wherein the first and second guide blocks are both elongated, and the second end of the chain is fixed to a distal end of the first guide block.

5. The cryopreservation box docking module of claim 2, wherein the receiving frame comprises an outlet for moving part of the chain links in and out, the receiving frame is vertically arranged relative to the upper surface of the shovel plate, and the outlet faces the upper surface of the shovel plate.

6. The cryopreservation box docking module of claim 1, wherein the receiving mechanism is connected with a side wall of the bin body.

7. The docking module of claim 1, further comprising a sliding assembly connected to the bin body and the blade for guiding the blade when the blade moves forward or backward.

8. The cryopreservation cartridge docking module of claim 7, wherein the sliding assembly comprises a first slide rail, a first slider, a connection block, a second slide rail and a second slider, wherein:

the first sliding rail is arranged on the bin body, and the first sliding block is arranged on the lower surface of the connecting block and is in sliding connection with the first sliding rail; the second sliding rail is arranged on the lower surface of the shovel plate, and the second sliding block is arranged on the upper surface of the connecting block and is in sliding connection with the second sliding rail.

9. The cryopreservation box docking module of claim 1, wherein the drive mechanism comprises a motor mounted outside the cartridge body, a drive shaft of the motor being connected with the sprocket.

10. A cryogenic storage apparatus comprising the cryopreservation cartridge docking module, the access port module and the cryogenic device of any one of claims 1 to 9; the low-temperature device is used for storing the freezing storage box in a low-temperature environment; the freezing box butt joint module is used for moving forwards and backwards through the shovel plate, taking the freezing box out of the access opening module, so that the freezing box can be transferred to the low-temperature device, or the freezing box taken out of the low-temperature device is placed in the access opening module.
