At the same time, since the No. 2 transmission belt 41 is transmitted between the two No. 2 rotating wheels 40, the synchronous rod 39 rotates synchronously with the rotating shaft 37. The synchronous rod 39 utilizes the meshing between the first bevel gear 42 and the second bevel gear 58, so that the second bevel gear 58 drives the mixing rotating rod 43 to rotate, and the mixing rotating rod 43 drives the multiple mixing blades 45 through the multiple mounting sleeves 44 fixedly connected to mix the deionized water and the sample. The sample is stirred and mixed, and at the same time, the rotating shaft 37 drives the two cams 38 to rotate, and reciprocatingly squeezes the push plate 34 to move upward, the push plate 34 drives the two push rods 33 to move upward reciprocatingly, and the two push rods 33 drive the mixing box 36 to move upward reciprocatingly, and cooperate with multiple mixing blades 45, so as to achieve rapid mixing of the sample and deionized water.
