Since nuts of different sizes have different weights, the gravity springs 20 contract differently. The heavier nuts are compressed more and enter the nut storage cabinet 4 through the first nut slideway 2. The nuts of medium weight are compressed and enter the nut storage cabinet 4 through the second nut slideway 3. The lighter nuts enter the nut storage cabinet 4 through the third nut slideway 5, completing the sorting of nuts of different sizes.
