| 摘要 | A ball bag stand and ball bag engagement structure includes a ball bag stand structure, a ball bag structure, protrudingly engaging structures, and cords. The protrudingly engaging structures each have a vertically smooth action force-free surface and an action force-applied surface with a protruding flange. A user can lift the ball bag by lifting the cords between the ball bag and the ball bag stand with one finger of the user single-handedly to thereby not only allow the action force-free surfaces of the fastening holes to press against the vertical smooth surface while sliding relative thereto, but also allow the action force-applied surfaces of the fastening holes to move away from the protruding flanges. Hence, the cords can be moved away from the protrudingly engaging structures with one finger of the user single-handedly, so that the user can remove the ball bag from the ball bag stand easily. | ||||||
