The first bevel gear 8 is horizontally distributed, and the two second bevel gears 9 are symmetrically distributed in the left and right directions. The outer radial sizes of the first bevel gear 8 and the second bevel gear 9 are consistent, so that the first bevel gear 8 and the second bevel gear 9 can be rotated in the same direction. angular velocity and linear velocity rotation; there are two rotating rods 10 and rotating blocks 11, both of which are horizontally distributed cylindrical structures, there are four first stirring plates 12 and four second stirring plates 13, and there are multiple pressure relief holes 14, which can reduce the resistance of the first stirring plates 12 and the second stirring plates 13 and improve the stirring efficiency of the first stirring plates 12 and the second stirring plates 13; there are two limiting sleeves 15, both of which are circular tubes, and there are four limiting rods 16, both of which are horizontally distributed cylindrical rods, and the limiting sleeves 15 and the limiting rods 16 can limit the rotating rod 10.

[0024] Working process: Turn on the power before use. The driving motor 5 is an electrical appliance with a built-in switch and can be manually operated.
