The movement of the connecting rod 15 will push the push plate 20 to move.

[0030] Working principle: First, when using the biological tissue cryopreservation device to cryopreserve biological tissue, the biological tissue to be preserved is placed inside the storage container 8. Then, the sealing cover 4 is closed, and the sealing cover 4 is moved, causing the sealing block 12 to move into the sealing groove 11. Once inside the sealing groove 11, the sealing block 12 seals the gap between the sealing cover 4 and the storage container 1. Liquid nitrogen is then added into the return groove 9 through the injection head 10. This return groove 9 cools the storage container 8, thus cryopreserving the biological tissue. When collecting biological tissue, the servo motor 19 drives the reciprocating screw 18. The rotation of the reciprocating screw 18 causes the threaded ring 17 to move. The movement of the threaded ring 17 causes the connecting plate 16 to move. The movement of the connecting plate 16 causes the connecting rod 15 to move. The guide cylinder 14 guides the connecting rod 15, allowing it to move smoothly. The movement of the connecting rod 15 pushes the push plate 20 to move. The movement of the push plate 20 pushes the storage container 8 to move. When the storage container 8 moves upward, it is easier for the staff to pick it up, thus improving work efficiency.
