[0023] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.

[0024] To further understand the content of the present invention, the present invention will be described in detail in conjunction with the accompanying drawings.

[0025] Combined with Figure 1 , a DNA kit with good fixing effect of the present invention includes a kit body 1. A box body fixing mechanism 3 is sleeved on the upper end of the kit body 1. A DNA reagent sealing tube 2 is movably sleeved on the box body fixing mechanism 3. The kit body 1 includes a fixed box 11. A lower gasket 12 is snap-fitted inside the fixed box 11. The box body fixing mechanism 3 includes a glass sheet 31 movably sleeved inside the fixed box 11. An adjusting rod 32 is sleeved in the middle of the glass sheet 31. A fixed cover plate 33 is arranged at the upper end of the fixed box 11. The adjusting rod 32 is inserted into the fixed cover plate 33. A rotating nut 34 is rotatably connected to the upper end of the adjusting rod 32. The DNA reagent sealing tube 2 includes a plurality of reagent tubes 21 sleeved inside the glass sheet 31. A sealing cover 22 is snap-fitted on the reagent tube 21.

[0026] Specifically, the lower gasket 12 is sleeved on the lower end of the fixed box 11 to protect the bottom of the reagent tube 21. The glass sheet 31 is movably clamped in the fixed box 11 and can be lifted and lowered within a certain range. The sealing cap 22 is directly inserted into the reagent tube 21 to block the reagent tube 21. After aligning multiple groups of reagent tubes 21 and inserting them into the glass sheet 31, the fixed cover plate 33 can be aligned with the fixed box 11 and sleeved. Then, the rotating nut 34 is aligned with the adjusting rod 32 and rotated. As the rotating nut 34 rotates, the fixed distance between the glass sheet 31 and the fixed cover plate 33 gradually decreases, increasing the extrusion force of the fixed cover plate 33 on the sealing cap 22. Thus, while fixing the reagent tube 21, the port of the reagent tube 21 is blocked. The combination of the reagent tube 21, the glass sheet 31, and the lower gasket 12 realizes fixation, preventing the reagent tube 21 from being collided during transportation. At the same time, the fixed box 11 and the fixed cover plate 33 can be stacked up and down to realize the transportation and fixation of multiple groups of reagent kits.
