[0035] Reference Figure 1The top of the workbench 1 is fixedly connected to the supporting frame 2, the bottom of the workbench 1 is fixedly connected to the freezing box 3, the top of the slide bar 4 is fixedly connected to the bottom of the supporting frame 2, and the top of the rack 7 is fixedly connected to the bottom of the supporting frame 2.

[0036] Specifically, the workbench 1 fixes the support frame 2, and the support frame 2 fixes the slide bar 4 and the rack 7, so that the slide bar 4 and the rack 7 are more stable, and the workbench 1 fixes the freezing box 3, so that the opening and closing of the sealing block 12 are more stable.

[0037] Working principle: When using the device, the test tube 20 containing stem cells needs to be placed in the placement groove 19 on the placement table 13 first, and then the connecting slider 16 is moved to move along the inner wall of the limiting slide groove 18, so that the bottom of the connecting slider 16 moves on the inner wall of the fixing groove 14, thereby squeezing the spring 15, and then driving the other side block 17 to move, so that the test tube 20 is placed along the inner wall of the placement groove 19, and then the connecting slider 16 is loosened, and the block 17 can be moved along the inner wall of the card groove 21 under the action of the spring 15, so as to fix the test tube 20;

[0038] By starting the motor 10, the gear 6 is driven to rotate outside the rack 7, so that under the action of the limit groove 8, the connecting slider 9 moves along the inner wall of the limit groove 8, so that the gear 6 can move more stably, thereby driving the connecting rod 5 to move, so that under the action of the directional slider 11, the connecting rod 5 can move more stably, so that the sealing block 12 can be driven to move up and down, thereby moving the placement table 13, so that the placement table 13 can be conveniently stored and taken out, thereby avoiding the low temperature harm of the freezing box 3 when the test tube 20 is manually taken out.
