The annular slider 641 slides in the annular slide rail 12 through a plurality of steel balls 642 to improve the smoothness of the rotation of the positioning ring 64. When the rotating rod 61 drives the gear 65 to rotate, the U-shaped stirring rods on both sides are rotated. The rack 67 stirs the raw materials in the reactor 1. Due to the meshing between the gear 65 and the driven gear 66, the driven gears 66 on both sides are driven to rotate in opposite directions at the same time, so that the connecting rod 68 is driven to stir the raw materials in the opposite direction through the paddle 69, thereby stirring the raw materials in multiple directions and quickly stirring the raw materials evenly.
