The test tube rack has a connecting column 13 fixedly connected to the top center, and a plug 14 fixedly connected to the top of the connecting column 13. The plug 14 is slidably inserted into the tube 7. The outer walls of both the tube 7 and the plug 14 have insertion holes 8, which pass through the tube 7 and the plug 14.

The left end of the output shaft of the motor 21 is fixedly connected to a transmission shaft 22. The outer wall of the left end of the transmission shaft 22 is fixedly sleeved with a bevel gear 23, which meshes with the bevel gear 20.

[0016] The test tube rack includes an upper ring plate 9, a middle ring plate 10 and a lower ring plate 11 arranged sequentially below the bottom of the upper ring plate 9. Several connecting rods 12 are fixedly connected between the outer walls of the upper ring plate 9, the middle ring plate 10 and the lower ring plate 11.
