A lifting component is arranged on the telescopic component, and a plurality of lifting components are transmission matched with the shaft 3 through an intermittent transmission component.

[0029] The motor 2 drives the shaft 3 to rotate, and at the same time drives the first stirring rod 4 to rotate, and the shaft 3 drives multiple first gears 7 to rotate through the second gear 8, so that multiple second stirring rods 9 rotate, and the first stirring rod 4 and the second stirring rod 9 rotate in opposite directions. At the same time, the shaft 3 enables multiple lifting components to operate intermittently through the intermittent transmission component, thereby driving the telescopic component to synchronously and intermittently telescope, and then the position of the second stirring rod 9 can be displaced intermittently, so as to achieve stirring at different positions, and cooperate with the opposite rotation characteristics of the first stirring rod 4 and the second stirring rod 9 to expand the stirring range and stirring intensity of the reactants, improve the stirring effect, and improve the reaction efficiency.
