The stator 600 is disposed around the turntable 510, and an inner surface of the stator 600 facing the turntable 510 is provided with inner teeth 610, and the inner teeth 610 are engaged with the outer teeth 310 of the solid phase reagent container 300. When the whole reagent kit 10 is carried on the rotary disk 510, the reagent kit 10 can be smoothly accommodated in the mounting gap 521 by the limiting and guiding functions of the partition 520; meanwhile, the positioning column 530 is inserted into the kit 10, so that the kit 10 is further correctly mounted on the turntable 510 under the limitation of the positioning column 530, the clamping stagnation phenomenon is prevented, the loading reliability of the kit 10 is ensured, and the accurate engagement of the inner gear teeth 610 and the outer gear teeth 310 is realized.

During operation, the turntable 510 drives the reagent kit 10 to rotate around the driving shaft 540, and during the rotation process of the turntable 510, as the outer gear teeth 310 on the solid-phase reagent container 300 are meshed with the inner gear teeth 610 on the stator 600, the reagent kit 10 rotates around the central shaft of the reagent kit 10 in the revolution process of the outer gear teeth 310 and the inner gear teeth 610 around the driving shaft 540, and the suspension in the solid-phase reagent container 300 generates vortex under the combined action of revolution and rotation, so that the solid particles of the magnetic particles are uniformly suspended in the liquid, and the generation of precipitation is avoided.
