After the drive motor 215 is started, the placement tray 212 at the output end is driven to rotate. After the placement tray 212 completes the rotation, the lower end of the rotating groove 222 set at the lower end rotates at the upper end of the rotating steel ball 223, and the placement tray 212 is rotated. After the rotation is completed, the sample inside the test tube can be rotated and mixed. When the placement plate 212 needs to be taken out, the upper fixed cover 211 set at the upper end of the storage bin 214 can be opened. After the upper fixed cover 211 is opened, the two groups of electric hydraulic cylinders 226 are started.
