By setting a square plate 20 in the second groove 19 and opening a clamping groove 21 on one side of the square plate 20, the clamping block 10 is slidably connected in the clamping groove 21. When the staff puts the storage tank 7 into the storage slot 6 and pushes it inward, so that the clamping block 10 extends into the clamping groove 21, and then rotates the storage tank 7, the square plate 20 will drive the connecting column 23 to push the cross column 22, so that the pair of arc-shaped sealing plates 17 slide upward and downward simultaneously in the third through groove 18, and the middle of the pair of arc-shaped sealing plates 17 is opened, so that the liquid nitrogen can flow into the storage slot 6 to freeze the embryonic stem cells. When the staff needs to take out the storage tank 7, only need to hold the first handle 9 and flip the storage tank 7 to make the pair of arc-shaped sealing plates 17 fit to seal a single storage slot 6, preventing the liquid nitrogen from flowing out through the storage slot 6. By opening a pair of second sliding grooves 25 on one side of the chassis 1 and setting second sliding blocks 26 in the second sliding grooves 25, the second sliding blocks 26 are fixedly connected to one side of the cabinet door 2. When the staff needs to take out the stored test tubes inside, they can choose to only open one side of the cabinet door 2, which can reduce the time of opening and closing the cabinet door 2 and improve work efficiency. By fixedly connecting a connecting block 28 to the top of the chassis 1,By setting a slidable U-shaped plate 29 at the top of the connecting block 28 and passing a pair of U-shaped plates 29 through and sliding them inside the cabinet door 2, the cabinet door 2 can be fixed when the cabinet door 2 is closed, preventing the cabinet door 2 from being opened randomly. By opening third sliding grooves 30 on both the upper and lower sides inside the chassis 1, the storage box 5 slides in the third sliding grooves 30 through third sliding blocks 31.
