By rotating the rotating head 21, under the rotation of the screw rod 22, the slider 23 slides up and down along the guiding member 24, and the effect of lifting adjustment can be achieved. Just stop adjusting to the corresponding water bath height.

[0040] Among them, the guiding member 24 can adopt a semi - enclosed housing, which is attached to the two side walls of the slider 23 for limiting and guiding it. It can be understood that the guiding member 24 can also adopt a straight rod passing through the slider 23 to achieve the specific guiding effect.

[0041] In this embodiment, please refer to Figure 1 , in order to shake the cryotube while placing it, and improve its resuscitation speed, a shaking assembly 3 is arranged between the lifting assembly 2 and the frame body 4. Among them, the shaking assembly 3 includes a connecting member 31, a locking member 32 and a hand - holding part 33. The connecting member 31 is rotatably connected to the movable end of the lifting assembly 2.
