A test tube 14 is snap-connected between the inside of the fixing ring 7 and the top of the placement base 9, and the upper end of the test tube 14 extends to the top of the storage rack 6.

[0033] A sliding hole 11 is provided inside the fixing rod 10 , and sliding grooves 12 are provided on both upper and lower sides of the fixing rod 10 . A pull rod 15 is slidably connected inside the sliding hole 11 , and a support bar 16 is slidably connected to the outside of the fixing rod 10 through the sliding groove 12 .

[0034] A semicircular limit strip is provided at the end of the pull rod 15 , and the inner side of the limit strip fits with the inside of the fixing rod 10 . The support strip 16 is a U-shaped structure, and both the pull rod 15 and the support strip 16 pass through the front side of the installation frame 1 .

[0037] Embodiment 2:

[0038] Based on the first embodiment, the specific working principle is as follows:

[0039] The central reagent rack is provided with an operating rod 5, which rotates around a base block 4. The state of a storage rack 6 is adjusted by rotating the operating rod 5. In general, the storage rack 6 is in a state such as Figure 1 In the state shown, the three storage racks 6 are on the same vertical line, so that the storage racks 6 can store multiple test tubes 14 at the same time through a limited space, and the space occupied by the multiple test tubes 14 is small;

[0040] By pulling the operating rod 5 to rotate around the base block 4, the pull rod 15 will drive the rotating block 13 to move away from the installation frame 1, so that the rotating block 13 rotates inside the fixed rod 10, and at the same time, the rotating block 13 will slide downward on the outside of the operating rod 5, so that the storage rack 6 moves away from the installation frame 1 as a whole, until the operating rod 5 drives the three storage racks 6 to be distributed in a stepped manner on the front side of the installation frame 1, so that the storage racks 6 appear as follows. Figure 2 In the state shown, the vertical spaces on the tops of the three storage racks 6 do not interfere with each other, which is convenient for placing and taking the test tubes 14. At the same time, the storage racks 6 are arranged in a stepped manner, so that the test tubes 14 inside the storage racks 6 do not block each other and are fully displayed, which is convenient for finding the reagents in a specific test tube;

[0041] During the movement of the storage rack 6, the storage rack 6 will drive the support bar 16 to slide on the front side of the installation frame 1 and the inner side of the slide rail 17, and support the entire storage rack 6 through the support bar 16, while keeping the storage rack 6 moving in the horizontal direction. The pull rod 15 located at the lower end of the installation frame 1 is pulled by the slide bar 18, so that the slide bar 18 applies a force toward the inside of the installation frame 1 to the pull rod 15, so that the pull rod 15 drives the fixed rod 10 to move in the direction close to the installation frame 1, and then the bottom storage rack 6 moves in the direction close to the installation frame 1. At this time, the storage rack 6 drives the two rotating blocks 13 to move in the direction close to the installation frame 1 through the fixed rod 10, and then applies a force in the direction close to the installation frame 1 to the operating rod 5, so that the operating rod 5 always rotates in the direction close to the installation frame 1, so that when the operating rod 5 is in a state without force, the pull rod 15 at the bottom can drive multiple storage racks 6 to return to the state as shown in the figure. Figure 1 Status shown;

[0042] The double-layer fixing strips 8 inside the fixing ring 7 have good elasticity, and the fixing strips 8 are distributed in a ring shape, so that when test tubes 14 of different sizes are installed inside the fixing ring 7, multiple fixing strips 8 are evenly distributed in a ring shape on the outer structure of the test tube 14, and test tubes 14 of different sizes are fixed by multiple fixing strips 8.
