[0021] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0022] Please refer to Figures 1-4, a stem cell transfer device, comprising a box body 1, a cover plate 3, a cooling frame 4 and a limiting mechanism 5. The cover plate 3 is arranged on the top of the box body 1, and the cover plate 3 is hinged to the box body 1. The cooling frame 4 is placed inside the box body 1. The limiting mechanism 5 includes a chute 6, a slider 7, a groove, a fixing plate 8, a telescopic rod 9 and a limiting block 10. The chute 6 is opened on the cooling frame 4. One end of the slider 7 is slidably connected to the chute 6, and the other end of the slider 7 passes through the box body 1. The groove is opened on the slider 7. One end of the fixing plate 8 is connected to one side of the box body 1. One end of the telescopic rod 9 is connected to the fixing plate 8, and the other end of the telescopic rod 9 is connected to the limiting block 10. The limiting block 10 extends into the groove. There are two limiting mechanisms 5.

[0023] When in use, first place the device at a designated position, then place the stem cell storage tube in the box body 1, and then cover the cover plate 3 to perform the transfer. The cooling frame 4 can achieve the cooling effect and prevent the temperature inside the box body 1 from being too high, which affects the storage of stem cells. When the cooling frame 4 is used for a long time and the cooling effect decreases and needs to be replaced, first start the telescopic rod 9 to separate the limiting block 10 from the groove, then push the slider 7 on the chute 6 to make the slider 7 pass through the box body 1, then lift the cooling frame 4 upward, and then the cooling frame 4 can be replaced.

[0024] The above device is not convenient to move. To solve this problem, in this embodiment, a pulley mechanism 2 is provided at the bottom of the box body 1, and there are several pulley mechanisms 2, and several pulley mechanisms 2 are symmetrically arranged.

[0025] The above device is not convenient to push. To solve this problem, in this embodiment, a push handle 12 is provided on one side of the box body 1, and the push handle 12 is fixedly connected to one side of the box body 1.

[0026] The above cover plate 3 is not convenient to lift. To solve this problem, in this embodiment, a handle 11 is provided on the top of the cover plate 3.

[0027] The stability of the above limiting mechanism 5 is relatively poor. To solve this problem, in this embodiment, the two limiting mechanisms 5 are symmetrically arranged.

[0028] The wear resistance of the above box body 1 is relatively poor. When the box body 1 is used for a long time, it is easy to wear. To solve this problem, in this embodiment, a wear-resistant layer is provided on the outer wall of the box body 1, and the wear-resistant layer is made of PVC material.
