Abstract

一种发球装置(10)，包括发球管道(12)及限位件(14)。发球管道(12)形成有入管口(122)。限位件(14)靠近入管口(122)并被设置在发球管道(12)的内壁(124)上，限位件(14)形成有至少两个限位点(141)，至少两个限位点(141)与内壁(124)形成圆形限位入口(129)，圆形限位入口(129)的直径与球体(20)的直径匹配以使球体(20)从圆形限位入口(129)进入入管口(122)。通过在入口处设置限位件(14)，从而限制球体(20)进入发球管道(12)的位置，减少球体(20)初始位置的随机性，使得发射出的球体(20)的运动轨迹稳定，有助于准确地发出目标运动轨迹的球。
