At the same time, it can make the rotating shaft 27 stir different positions in the box body 10, and also make the added reagent be transported to different areas in the box body 10 through the through holes 23 provided on the rotating shaft 27. With the stirring of the stirring rod 22, the mixing quality is greatly improved. At the same time, during the reciprocating movement of the guide plate 5, the installed roller 7 will pull the belt 4. During the reciprocating movement of the roller 7, the belt 4 drives the roller 7 to rotate through the cooperation with the elastic member 24. The rotation of the roller 7 drives the rotation of the box body 10, and the rotation of the box body 10 can drive the internal reagent to shake accordingly.
