[0020] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0021] The following is combined with Figure 1-4 This application is described in further detail.

[0022] A biological sample liquid mixing device includes a mixing machine body 4 and a tray 8. The tray 8 is arranged on the body 4. A fixing plate 9 is provided on the tray 8. A positioning block 2 is provided on the fixing plate 9. Two positioning blocks 2 are provided on the fixing plate 9. The positioning blocks 2 play a role in positioning and fixing a detection box containing multiple sample liquid test tubes.

[0023] A fixing rod 3 is threadedly connected to the positioning block 2. A fixing hole 10 is defined in the fixing plate 9. Multiple fixing holes 10 are provided on the fixing plate 9. One end of the fixing rod 3 abuts against the positioning block 2, while the other end of the fixing rod 3 is threaded into the fixing hole 10. The multiple fixing holes 10 facilitate adjustment of the positioning block 2 on the fixing plate 9 according to the shape and size of the test cartridge, providing ease of use.

[0024] A U-shaped plate 6 is provided on the fixed plate 9. Two U-shaped plates 6 are provided on the fixed plate 9. The U-shaped plate 6 is threadedly connected to a threaded rod 5. The threaded rod 5 is threadedly connected to the fixing hole 10. The U-shaped plate 6 is convenient for positioning and fixing a single test tube, and is convenient for the mixer to mix the sample liquid in a single test tube.

[0025] The U-shaped plate 6 is made of elastic material, which can be elastically deformed when subjected to force, making it convenient for the U-shaped plate 6 to position and fix a single test tube. A protective layer 1 is fixedly provided on the positioning block 2 to prevent the positioning block 2 from scratching the box body of the test box.
