[0026] The bracket 2 is provided with a plurality of centrifuge tube holes 7, and the centrifuge tube holes 7 are used to place centrifuge tubes. The centrifuge tube holes 7 are provided with a limiting device 8, and the limiting device 8 can horizontally limit the position of the centrifuge tube and the centrifuge tube hole 7. When the diameter of the centrifuge tube is smaller than the diameter of the centrifuge tube hole 7, the centrifuge tube can also be well fixed to prevent it from shaking in the centrifuge tube hole 7.

[0027] The limiting device 8 is a circular ring with an opening on one side, and the limiting device 8 has a certain elasticity and can be used to accommodate centrifuge tubes of different specifications. The limiting device 8 is used to horizontally limit the centrifuge tubes. The length and width of the magnetic plate 3 match the length and width inside the cavity 4. When the magnetic plate 3 is placed in the cavity 4, it is clamped with the cavity 4.

[0028] The base 1 is provided with a plurality of circular holes 9, which correspond one to one with the centrifuge tube holes 7. The first side panel 5 is provided with two through holes 10, and a protrusion 11 is provided on the outer edge of the through hole 10 away from the base 1. The middle part of the first side panel 5 is provided with a rectangular hole 13 which is convenient for the magnetic plate 3 to enter and exit and is connected to the cavity 4; the sizes of the two through holes 10 can be adapted to 15ml and 50ml centrifuge tubes respectively.
