[0019] In order to more clearly understand the above-mentioned objects, features, and advantages of the present utility model, the following further describes the present utility model with reference to the accompanying drawings and embodiments. It should be noted that, without conflict, the embodiments of the present application and the features in the embodiments can be combined with each other.

[0020] In the following description, many specific details are set forth in order to fully understand the present utility model. However, the present utility model can also be implemented in other ways different from those described herein. Therefore, the present utility model is not limited by the specific embodiments disclosed in the following specification.

[0021] Embodiment 1: As Figures 1 - 4As shown in the figure, the utility model provides a multifunctional auxiliary bracket for durum wheat straws, including: a cover plate 1, on the top of the cover plate 1, a plurality of placement holes 2 are equidistantly arranged, on the inner surface of the plurality of placement holes 2, a plurality of protrusions 3 are equidistantly fixedly connected, near the edge at the bottom of the cover plate 1, a limiting groove 9 is provided, in the inner surface of the limiting groove 9, a storage box 4 is inserted, the plurality of placement holes 2 are all circularly arranged, and the plurality of protrusions 3 are all semi-circularly arranged.

[0022] The overall effect achieved by the entire Embodiment 1 is that the cover plate 1 is made of plastic material, and the protrusion 3 is made of soft rubber material. During the use process, take out the durum wheat straw from the liquid nitrogen tank, insert the durum wheat straw along the placement hole 2 into the cover plate 1. After insertion, the durum wheat straw can be clamped by the inner protrusion 3. Then separate the cover plate 1 and the storage box 4, place the cover plate 1 in a water bath for resuscitation. The cover plate 1 plays the role of a buoy. When attaching, place an ice pack into the storage box 4. Thus, after the resuscitation process, the storage box 4 can be inserted into the limiting groove 9 at the bottom of the cover plate 1 to form a whole. It can not only slow down the fusion speed of the ice pack, but also refrigerate the samples in the durum wheat straws in the cover plate 1 through the ice pack to prevent the biological cell samples from undergoing qualitative changes due to excessive temperature. At the same time, after the connection between the cover plate 1 and the storage box 4 is completed, it can be used as a centrifuge tube rack during freezing. Then, after cleaning the water droplets on the outside, it is placed in a clean bench for subsequent experiments. This auxiliary bracket can be used as a buoy and a centrifuge tube rack, and can refrigerate the samples in the durum wheat straws, eliminating the need to frequently change tools or search for suitable containers, thus improving work efficiency.

[0023] Embodiment 2: As Figures 1 - 4 shown, on the outer surfaces of both sides of the storage box 4, support frames 5 are fixedly connected, on the outer surfaces of the two support frames 5, lead screws 10 are threadedly penetrated, at one end of each of the two lead screws 10, a connection block 12 is rotatably connected, on one side outer surface of each of the two connection blocks 12, a clamping block 7 is fixedly connected, on the outer surfaces of both sides of the cover plate 1, clamping grooves 8 are provided, the two clamping blocks 7 and the two clamping grooves 8 are respectively in a matching setting, on the outer surfaces of the two support frames 5, guide rods 11 are movably penetrated, at one end of each of the two guide rods 11, it is fixedly connected to the other side outer surface of the connection block 12, and at the other end of each of the two guide rods 11, a handle 6 is fixedly connected, and the two support frames 5 are in an L-shaped setting.

[0024] The overall effect achieved by the entire Embodiment 2 is that after the cover plate 1 and the storage box 4 are docked, the lead screw 10 can be rotated, and with the cooperation of the guide rod 11, the connection block 12 is driven to move, so that the clamping block 7 moves into the clamping groove 8 to strengthen the connection between the cover plate 1 and the storage box 4, improving the convenience of the overall movement during movement. At the same time, through the outer handle 6, the convenience of movement is further improved. When separating, only need to rotate the lead screw 10 in the reverse direction to separate the clamping block 7 from the clamping groove 8, and then separate the cover plate 1 and the storage box 4.

[0025] Working principle: During use, take out the thick straw from the liquid nitrogen tank and insert the thick straw into the cover plate 1 along the placement hole 2. After insertion, the inner protrusion 3 can clamp the thick straw. Then, separate the cover plate 1 from the storage box 4 and place the cover plate 1 in a water bath for resuscitation. The cover plate 1 acts as a buoy. When attaching, place an ice pack into the storage box 4. Thus, after the resuscitation process, the storage box 4 can be inserted into the limit groove 9 at the bottom of the cover plate 1 to form an integral whole. The lead screw 10 can be rotated, and with the cooperation of the guide rod 11, drive the connecting block 12 to move, so that the clamping block 7 moves into the clamping groove 8 to strengthen the connection between the cover plate 1 and the storage box 4. This can not only slow down the melting speed of the ice pack, but also cool the sample in the thick straw in the cover plate 1 through the ice pack to prevent the biological cell sample from undergoing qualitative change due to excessive temperature. At the same time, after the connection between the cover plate 1 and the storage box 4 is completed, it can be used as a centrifuge tube rack during freezing. Then, after cleaning the water droplets on the outside, move the bracket to the laminar flow hood through the handle 6 for subsequent experiments. This auxiliary bracket can be used as a buoy and a centrifuge tube rack, and can cool the sample in the thick straw, eliminating the need to frequently change tools or find suitable containers, thus improving work efficiency.
