发明名称 Basketball training assembly with multiple hoops
摘要 A basketball training assembly with multiple hoops comprises a backboard, an innermost circular hoop, a middle semi-circular hoop, and an outermost semi-circular hoop. Each of the hoops has a net, and the hoops are concentric. The hoops are connected to the backboard perpendicularly by connecting means such as screws and nuts. The diameter of the innermost hoop is the smallest, and the diameter of the outermost hoop is the largest. The distance between every two hoops is greater than the diameter of a basketball for the basketball passing therethrough.
