[0024] When it is needed to extract the solute from the solution composed of another solvent with a solvent, the cap 2 is first opened through the handle arranged on the cap 2, then the two solvents are sequentially added into the extraction tank 1, then the cap 2 is closed on the extraction tank 1, then the motor 201 is started, the motor 201 drives the stirring rod 203 to rotate through the rotating rod 202, when the stirring rod 203 rotates rapidly, the moving plate 205 moves to one side of the fixed plate 204 under the action of the centrifugal force to overcome the elastic force of the tension spring 207, then the stirring rod 203 is exposed to contact with the solvent, then the stirring rod 203 stirs the two solvents to improve the extraction efficiency.

[0025] When the extraction is completed, the motor 201 is closed, wherein the motor 201 can adopt a servo motor with a locking function, so that the rotating rod 202 does not rotate or rotates slowly when the motor 201 is closed, when the centrifugal force on the moving plate 205 disappears, the moving plate 205 is reset under the action of the tension of the tension spring 207, so that the telescopic rubber sleeve 206 is expanded to increase the contact area with the reaction liquid, thereby blocking the rotating reaction liquid to quickly calm down, so that the extracted reaction liquid quickly stratifies, by installing the fixed plate 204, the moving plate 205, the telescopic rubber sleeve 206 and the tension spring 207 on the stirring rod 203, when the reaction liquid is stirred and extracted, the stirring rod 203 is exposed to contact with the reaction liquid, thereby facilitating the stirring of the reaction liquid and accelerating the extraction, when the extraction is completed, the telescopic rubber sleeve 206 can be quickly expanded to increase the contact area with the reaction liquid, thereby blocking the rotating reaction liquid to quickly calm down, further improving the stratification rate of the reaction liquid after extraction.
