Through the adsorption plate 81 on the receiving plate 8 and the receiving plate 10 The adsorption plate 81 on the storage component 9 is adsorbed as a whole, thereby realizing the overall acceptance of the storage component 9, so as to facilitate the storage and preservation of different samples. When the corresponding sample needs to be taken out for testing, the servo motor drives the rotating wheel 6 to rotate, and the rotating wheel 6 drives the conveyor belt 7 to rotate as a whole. In the process of rotation of the conveyor belt 7, it drives the receiving plate 8 to rotate and drives the storage component 9 to move as a whole. When the storage component 9 reaches the placement port, the hydraulic rod 16 is extended as a whole. In the process of extension of the hydraulic rod 16, the storage component 9 is pushed, so that the storage component 9 that accepts the corresponding sample is pushed out as a whole, which is convenient for subsequent sample testing.
