Then, the placement box 3 is placed into the box body 1, and the placement box 3 is pushed so that the first hook 15 fixed on one side contacts the first buckle 16 provided on the box body 1. By pressing or pushing the first buckle 16, the first buckle 16 and the first hook 15 are engaged, thus completing the fixation of the placement box 3 in the box body 1.

[0023] The partition 4 allows for the partitioning of cooling ice packs, resulting in a more even distribution of the ice packs within the placement box 3. This helps the cold air diffuse from different areas into the box 1, improving the uniformity of temperature distribution within the box 1. The combination of the first hook 15 and the first buckle 16 enables quick and easy fixing of the placement box 3 to the box 1, reducing the possibility of displacement of the placement box 3 during transport and ensuring the stability of the cooling ice packs.

[0024] Meanwhile, the fastening method of the first hook 15 and the first buckle 16 not only makes it easy for users to quickly install the placement box 3, but also allows the placement box 3 to be easily removed by unfastening when the cooling ice pack needs to be replaced or replenished, thus improving the convenience of using the device. This structure is compatible with the detachable feature of the placement box 3, further enhancing the practicality of the device in outdoor scientific research, emergency rescue and other scenarios, and helping to meet the needs of mobile preservation of stem cell samples.

[0025] In a further preferred embodiment of the present invention, mounting blocks 13 are symmetrically fixed on the inner wall of the box 1, and limiting rods 14 are fixed on the mounting blocks 13, the limiting rods 14 penetrating the placement frame 5.

Subsequently, according to the placement requirements of the stem cell sample test tube 6, the position of the placement rack 5 can be adjusted along the limiting rod 14. After adjusting to a suitable position, the test tube 6 can be placed in the corresponding position on the placement rack 5 for storage.

[0027] The symmetrical arrangement of the mounting block 13 and the limiting rod 14 provides stable support and guidance for the placement rack 5, reducing tilting or shaking of the placement rack 5 during device movement and ensuring the stability of the test tube 6 and the internal stem cell sample. The limiting rod 14 penetrates the structure of the placement rack 5, making the installation and disassembly of the placement rack 5 simple and convenient for users to replace different specifications of the placement rack 5 according to actual needs, thus improving the adaptability of the device.

[0028] In a further preferred embodiment of the present invention, a heat-insulating pad 2 is provided inside the box body 1, and a pad block 7 is fixed inside the placement rack 5. The pad block 7 has an arc-shaped groove for padding and protecting the test tube 6.
