[0002] In medical tests and experiments, reaction cups are mainly used to mix and dissolve reagents, store biological samples, accurately measure liquid volume, observe reaction processes, and prepare standard products. They are one of the essential basic tools in the laboratory.

[0003] At present, stacked reaction cups are mostly used, which are convenient to take and not easy to mess up. Some simple equipment is used to pull the reaction cup downward. A common method is to set an inward structure at the lower end of the device itself, or to set a spring inside to clamp and fix the reaction cup. Although this design is simple and convenient, it sometimes causes multiple reaction cups to be pulled out at one time. In addition, the diameter of the internal cup barrel is usually fixed, which limits its applicability to reaction cups of different specifications. Utility Model Content

An L-shaped frame is connected to the side wall of the storage tube near the movable groove, and a screw is threadedly connected to the L-shaped frame, and one end of the screw extends into the movable groove and is connected to the top block.

[0006] Furthermore, an L-shaped plate is connected to the rear side of the storage tube, a hanging ring is slidably connected to the L-shaped plate, a fixing seat is connected to the side of the hanging ring away from the storage tube, and fixing holes are symmetrically arranged on the fixing seat.

[0007] Based on the above features, the hanging ring cooperates with the L-shaped plate to facilitate quick hanging and fixing of the reaction cup.

[0008] Furthermore, the upper and lower ends of the storage tube are rotatably connected with sealing covers, the inner side of the sealing cover is connected with a sealing ring, and the front side of the storage tube is provided with a transparent viewing window.

[0009] Based on the above features, the sealing cover and the sealing ring can prevent the inside of the storage tube from being contaminated, thereby ensuring the safety and hygiene of the reaction cup. The transparent viewing window makes it easy to observe the number of reaction cups in the storage tube and replenish them in time.

[0010] Furthermore, a plurality of fixing blocks are connected to the edge of the upper end of the limiting cylinder, and a clamping ring cooperating with the fixing block is integrally formed at the upper inner end of the storage cylinder, and the fixing block is fixed to the clamping ring by bolts.

[0011] Based on the above features, the fixing block cooperates with the clamping ring to facilitate the limiting cylinder to be clamped in the storage cylinder, which is convenient for taking and placing, and the bolt can increase the stability of the limiting cylinder.

[0012] Furthermore, the clamping block is provided with arc-shaped inclined surfaces symmetrically up and down on one side away from the top block.

[0013] Based on the above features, the arc-shaped slope facilitates the reaction cup to smoothly push the clamping block to move when it is pulled out, and the operation is labor-saving and smooth.

[0014] Furthermore, a support plate is connected to the bending part of the L-shaped frame.

[0015] Based on the above features, the support plate can increase the stability of the L-shaped frame.
