[0007] Preferably, the transparent tube is formed by two semi-arc shells spliced ​​together by glue, and the tops of the two semi-arc shells are threadedly connected to the same cap.

[0008] Preferably, the multiple triple sugar iron culture medium models are all made by 3D printing, and the multiple triple sugar iron culture medium models are all colored.

[0009] Preferably, a storage groove is provided on the base, a storage drawer is movably installed in the storage groove, and a handle is provided on the outside of the storage drawer; the storage drawer can store the transparent tube.

[0010] Preferably, self-locking bearings are fixedly installed on the inner sides of the two vertical plates, end shafts are fixedly installed on the inner rings of the two self-locking bearings, and the two end shafts are fixedly installed on both sides of the fixing bar; the self-locking bearings will not rotate without external force.

[0011] Compared with the prior art, the utility model has the following advantages:

[0012] 1. Prepare two semi-arc shells. The three-sugar iron culture medium model is obtained by 3D printing. The three-sugar iron culture medium model has a specific color. Then put the 3D printed three-sugar iron culture medium model into it. The two semi-arc shells are glued together to form a transparent tube. The preparation is simple;

[0013] 2. The transparent tube is clamped at the position of the arc-shaped bayonet, and the fixing strip can be adjusted to adjust the viewing angle of the transparent tube. The storage drawer can store the transparent tube;

[0014] The utility model obtains a three-sugar iron culture medium model by 3D printing and places it in two semi-arc shells, and the two semi-arc shells are glued together with glue. The preparation is simple, and the observation angle of the transparent tube can be adjusted. BRIEF DESCRIPTION OF THE DRAWINGS
