In the utility model, the motor drives gear 1 to rotate, and gear 2 will rotate on the circumferential side of gear 1 and mesh with the teeth at the same time. Gear 2 is supported by the rotating rod to ensure the smooth rotation of gear 2. While gear 1 and gear 2 rotate, they drive the rotating shaft and the stirring rod connected to the side wall of the rotating shaft to rotate, so as to mix The anti-corrosion coating inside the mixing box is stirred and mixed. When it is in use, the motor drives the gear one to rotate. Since the gear one and the gear two are meshed, the gear two will rotate on the circumferential side of the gear one and mesh with the teeth at the same time. The fixed rod one, the rotating rod and the fixed rod two support the gear two to ensure that the gear two is always between the gear one and the fixed ring when rotating, and maintains a state of meshing with the gear one and the teeth at the same time, to ensure the smooth rotation of the gear two.
