[0033] The selected embryo tube can be accurately and quickly taken out by selecting the limiting assembly 2. The output end of the motor 22 can drive the rotating column 21 to rotate, the rotating column 21 can drive the rotating disc 23 to rotate, and the rotating disc 23 can rotate the limiting cylinder 25 thereon to below the fixing mechanism, so as to realize the taking of the specified embryo tube 27 without opening the box door and avoiding changing the temperature in the box 1. The specified embryo tube can be taken out of the box 1 by the taking assembly 3, and other embryo tubes will not be directly exposed to the air during the taking process. When the rotating disc 23 rotates and moves the specified limiting cylinder 25 to below the fixing mechanism, the electric push rod 35 can drive the fixing mechanism to move downward to the specified position. The four clamping plates 314 in the fixing mechanism can be inserted into the four insertion slots 36 on the limiting cylinder 25. Subsequently, the electric push rod 35 can drive the fixing mechanism to pull the limiting cylinder 25 in the containing groove 24 upward, so as to complete the quick taking of the single embryo tube 27. The utility model has high practicability and can avoid interfering with the preservation of other embryos.

[0034] As shown in Figure 8 The outer wall of the limiting cylinder 25 is provided with a plurality of air holes 28 in a ring shape at the bottom. The air holes 28 are located above the rotating disc 23.

[0035] The air holes 28 facilitate the embryo tube 27 in the limiting cylinder 25 to maintain an appropriate temperature.

[0036] As shown in Figure 5 and Figure 6 The fixing mechanism includes an adjusting screw 37. The outer wall of the adjusting screw 37 is threadedly connected with the inner wall of the middle part of the upper end of the moving cylinder 32. The lower end of the adjusting screw 37 is rotationally connected with a push plate 38. The lower middle part of the push plate 38 is fixedly installed with a conical block 39.

[0037] The adjusting screw 37 is rotated, which can drive the push plate 38 and the conical block 39 to move up and down.

[0038] As shown in Figure 6 The inner wall of the moving cylinder 32 is fixedly installed with positioning rings 310 at the upper and lower parts. The edges of the upper and lower ends of the push plate 38 are lapped with the opposite sides of the two positioning rings 310. The inner wall of the middle part of the moving cylinder 32 is provided with guide grooves 311 at the left and right positions. The two guide grooves 311 are located between the two positioning rings 310. The outer wall of the push plate 38 is slidably connected with the inner wall of the two guide grooves 311.

[0039] When the push plate 38 is in contact with the top positioning ring 310, the conical block 39 is away from the four arc-shaped clamping plates 313, so that the four clamping plates 314 are retracted due to the elastic force of the elastic members 315. When the push plate 38 is in contact with the bottom positioning ring 310, the conical block 39 is squeezed into the middle of the four arc-shaped clamping plates 313, so that the four clamping plates 314 are squeezed and away from each other, which facilitates the extension into the corresponding four insertion slots 36. The two positioning rings 310 mainly play a positioning role.

[0040] As Figure 6 and Figure 7 As shown in the drawings, the inner wall bottom of the moving cylinder 32 is fixedly provided with four telescopic rods 312 arranged in a ring shape, one end of each of the four telescopic rods 312 close to the axis of the moving cylinder 32 is fixedly provided with an arc-shaped clamping plate 313 matched with a conical block 39, and the bottom of the side of each of the four arc-shaped clamping plates 313 away from the axis of the moving cylinder 32 is fixedly provided with a clamping plate 314 matched with a plurality of insertion grooves 36.

[0041] When the four arc-shaped clamping plates 313 are pressed by the conical block 39, the four telescopic rods 312 are telescoped and press the elastic members 315, and the four clamping plates 314 are away from each other and inserted into the corresponding four insertion grooves 36.

[0042] As Figure 7 shown, the outer side of each of the four telescopic rods 312 is movably sleeved with an elastic member 315, and the four elastic members 315 are located between the arc-shaped clamping plate 313 and the inner wall of the moving cylinder 32.

[0043] The elastic member 315 is a spring, and mainly plays a resetting role for the clamping plate 314 and the arc-shaped clamping plate 313.

[0044] As Figure 4 shown, the rear right part of the box body 1 is fixedly provided with a telescopic column 316, and the output end of the telescopic column 316 is fixedly connected with the lower end of the rear connecting plate 34.

[0045] The telescopic column 316 has a guiding and limiting effect on the movement of the moving cylinder 32.

[0046] The working principle of the utility model is as follows: in use, the sealed box door is opened, the embryo tube 27 to be preserved is placed in the elastic breathable sleeve 26 in the limiting cylinder 25, then the limiting cylinder 25 is inserted into the corresponding containing groove 24 in sequence by the rotation of the rotating disc 23, the temperature control mechanism is prior art, and is mainly used for keeping the temperature inside the box body 1 and ensuring the activity of embryo preservation.

[0047] When one of the embryo tubes 27 needs to be taken out, the motor 22 is started, the output end of the motor 22 can drive the rotating column 21 to rotate, the rotating column 21 can drive the rotating disc 23 to rotate, the rotating disc 23 rotates the specified limiting cylinder 25 thereon to below the four arc-shaped clamping plates 313, then the electric push rod 35 is started, the output end of the electric push rod 35 can drive the moving cylinder 32 to move to a suitable position, at this time, the bottom of the moving cylinder 32 just covers the top of the limiting cylinder 25, the adjusting screw 37 is rotated, the adjusting screw 37 drives the push plate 38 to move downwards and contact the bottom positioning ring 310, at this time, the tapered block 39 extends into the middle position of the four arc-shaped clamping plates 313, the four arc-shaped clamping plates 313 are pressed and compress the four elastic members 315, the four telescopic rods 312 are retracted, the four clamping plates 314 move away from the axis of the moving cylinder 32, the four clamping plates 314 extend into the four insertion grooves 36 at the top of the limiting cylinder 25, so as to fix the limiting cylinder 25, then the electric push rod 35 is started, the output end of the electric push rod 35 drives the limiting cylinder 25 to move upwards, so that the limiting cylinder 25 extends out of the box body 1, then the user reversely rotates the adjusting screw 37, the adjusting screw 37 drives the push plate 38 to move upwards and contact the top positioning ring 310, so that the limiting cylinder 25 is quickly separated from the moving cylinder 32, and the user can subsequently take out the embryo tube 27 therefrom. In this process, the taking out of the single embryo tube 27 will not affect the preservation of other embryo tubes 27, the practicability is high, and the activity of embryo preservation can be ensured.

[0048] The starting of the motor 22 and the electric push rod 35 is mainly controlled by the control system of the device, through programming, the rotating mode of the motor 22 is to rotate a specified angle and then stop and rotate again, and the rotating angle mainly depends on the distribution of the limiting cylinder 25 on the rotating disc 23. When the electric push rod 35 pushes the moving cylinder 32 into the box body 1, the position of the moving cylinder 32 is directly above the limiting cylinder 25, and when the limiting cylinder 25 needs to be clamped, the electric push rod 35 needs to drive the moving cylinder 32 to move downwards, and when the embryo tube 27 is taken out, the electric push rod 35 needs to drive the moving cylinder 32 to move upwards. Since the size of the limiting cylinder 25 is fixed, the three movements of the electric push rod 35 can be controlled through programming.

[0049] The basic principle and main features of the present application and the advantages of the present application are shown and described above. Those skilled in the art should understand that the present application is not limited by the above examples, and the above examples and descriptions in the specification are only to illustrate the principle of the present application.
