At the same time, the single-chip computer 2 is controlled to turn on the motor 4. The output shaft of the motor 4 drives the rotating shaft 31 to rotate. Under the restriction of the slide 5, the rotation of the rotating shaft 31 drives the rotating rod 33 through the support plate 32 with the rotating shaft 31 as the The center rotates. Due to the presence of the gear ring 39, the rotating rod 33 rotates around the rotating shaft 31. At the same time, the gear ring 39 drives the rotating rod 33 to rotate by itself through the meshing gear 38, causing the fixing seat 35 to drive the stirring blade 36 to rotate. The presence of the resistance-reducing hole 37 reduces the stirring resistance, making stirring faster, mixing the cooling water, and making the water cooling more even.
