A first bevel gear 12 is coaxially fixedly connected to the rotating shaft 6, and the drive motor 5 is used to drive the first bevel gear 12 on the rotating shaft 6 to rotate. A rotating shaft 12 is coaxially fixedly connected to the rotating rod 11. The second bevel gear 13 meshes with the first bevel gear 12. The upper end of the rotating rod 11 rotates vertically through the protective cover 3 and is fixedly connected to the lower end of the centrifuge tube 2 at the center position. The rotation of the first bevel gear 12 drives the meshing second bevel gear 13 to rotate, and the rotation of the second bevel gear 13 drives the coaxially connected rotating rod 11 to rotate smoothly under the support of the bracket 10. The lower ends of the centrifuge tube 2 located on both sides of the rotating rod 11 are fixedly connected to limit blocks 14. The lower ends of the two limit blocks 14 are embedded with balls 15. The upper end of the protective cover 3 is provided with an annular limit groove 16. The two balls 15 are inserted into the annular limit groove 16 and roll and abut against each other. The rotation of the rotating rod 11 drives the centrifuge tube 2 to rotate smoothly under the limiting action of the balls 15 on the limit blocks 14 and the annular limit groove 16 on the protective cover 3, which improves the rotational stability of the test tube 8 in the centrifuge tube 2 and prevents the medicine in the test tube 8 from spilling out.

[0023] Several cylindrical seats 7 are fixedly connected to the bottom of the centrifuge cylinder 2. Each cylindrical seat 7 is equipped with a test tube 8. A limiting assembly for the test tubes 8 is provided on the annular inner wall of the centrifuge cylinder 2 near the upper end. The limiting assembly includes an annular block 17 fixedly connected to the annular inner wall of the centrifuge cylinder 2 near the upper end. Each annular block 17 has several circular through holes 18, which are evenly distributed around the annular block 17. Several test tubes 8 pass through these circular through holes 18. Each cylindrical seat 7 has an arc-shaped slot 19 at its upper end, which is positioned opposite the circular through holes 18.

The lower ends of the test tubes 8 are respectively inserted into the arc-shaped slots 19 on several cylindrical seats 7, which effectively fixes the test tubes 8 and makes it convenient and quick to position the test tubes 8 in the centrifuge tube 2. The structure is simple and practical. After the sealing cap 9 is closed, the drive motor 5 on the support seat 4 is started, so that the drive motor 5 drives the first bevel gear 12 on the rotating shaft 6 to rotate. The rotation of the first bevel gear 12 drives the meshing second bevel gear 13 to rotate. The rotation of the second bevel gear 13 drives the coaxially connected rotating rod 11 to rotate smoothly under the support of the bracket 10. The rotating rod 11 drives the centrifuge tube 2 to rotate smoothly under the limiting action of the ball bearing 15 on the limiting block 14 and the annular limiting groove 16 on the protective cover 3, which improves the rotational stability of the test tubes 8 in the centrifuge tube 2 and prevents the medicine in the test tubes 8 from spilling out.
