This invention is a “High-Efficiency and Manpower-Saving Ball Collecting Device” which is designed with a combination of a collecting component and two sets of ball collecting module to achieve a high efficiency of ball collecting only by a low cost and simple design. The collecting component has an accommodation space being used for accommodating at least one ball such that the ball can be collected into the accommodation space by rotating the collecting component backward and forward. The ball collecting module is pivoted on the collecting component such that an angle is formed between the ball collecting module and a rotation axle of the collecting component, and the angle is smaller than 90 degrees or equal to 90 degrees. A constant distance between the ball collecting module and a plane is maintained when the ball is collected by the ball collecting device.

包含「收球本體」與「集球連桿組」。收球本體具有用以容置球體的容置空間，以藉由轉動該收集組件而將球體收集至容置空間中。當收球裝置進行球類收集時，集球連桿組與平面保持一恆定距離。

可確實解決現有打網球者所遇到每次訓練後需耗費時間撿球的問題，並且未來有機會可以變成受歡迎之商品，以提高台灣此類運動器材產品之競爭力，並有潛力可進軍世界市場。
