请参阅图1-4，图示中的电磁抛投器，电磁抛投器，包括抛投器发射筒1和控制装置2，所述控制装置2固定在抛投器发射筒1尾端，且抛投器发射筒1底部固定有可以减小发射后坐力的稳定支撑架3，所述抛投器发射筒1内设有电枢4。且抛投器发射筒1尾端开有负压孔22，通过括抛投器发射筒1和控制装置2，实现抛投的精准投放。
稳定支撑架3包括握持架5、移动套6、限位板7、缓冲件8和限位销9，所述握持架5固定在抛投器发射筒1尾端底部外侧，且移动套6套在抛投器发射筒1前端底部外侧，所述限位板7设有两个，且对称分布在移动套6两 侧，并均与抛投器发射筒1底部外侧固定，靠近抛投器发射筒1端口的所述限位板7通过缓冲件8与移动套6固定，且另一限位板7通过限位销9与移动套6一侧滑动插接，通过稳定支撑架3降低抛投器发射筒1发射时产生的后坐力，从而增加抛投精准度。
缓冲件8包括伸缩杆20和缓冲弹簧21，所述伸缩杆20两端分别与限位板7和移动套6固定，且缓冲弹簧21套在伸缩杆20外侧，通过缓冲件8减少后坐力带动的冲击。
握持架5包括连接板10、握持柱11和顶紧弹簧12，所述连接板10与抛投器发射筒1尾端底部固定，且连接板10内开有连接槽13，所述握持柱11一端位于连接槽13内，并与连接槽13内壁滑动连接，所述顶紧弹簧12一端与连接槽13内壁固定，且另一端与握持柱11一侧固定，通过握持架5实现人员手动握持时，使握持拿捏更加舒服。
控制装置2包括控制器14、储能电容15、电源电池16和磁感线圈17，所述控制器14与储能电容15和电源电池16电性连接，且电源电池16与储能电容15电性连接，所述储能电容15与磁感线圈17电性连接，且磁感线圈17成螺旋状安装与抛投器发射筒1内，通过控制装置2实现调节电压等，从而可以控制抛射速度和距离。
具体的实施方式：在需要抛投时，将抛投物品一端塞入抛投器发射筒1内，然后通过控制器14使电源电池16给储能电容15供电，再通过储能电容15使抛投器发射筒1内的磁感线圈17通电，并瞬间产生强磁场，推动电枢4运动，电枢4带动抛投物抛射出去，在电枢4抛投时，会产生一个反向后坐力，此时抛投器发射筒1会有一个向后运动的趋势，通过缓冲弹簧21和顶紧弹簧12的弹性形变，抵消发射时产生的后坐力，从而使抛投器发射筒1端口 处抖动范围小，抛投更加精准，同时通过抛投器发射筒1尾端开通的负压孔22，使抛投器发射筒1内腔一直处于一个正常压强的情况，避免负压，本实用新型通过可以减小发射后坐力的稳定支撑架3和负压孔22的配合作用，使抛投器发射筒1在驱动电枢4前进时，有效的减少其产生的后坐力，从而使其抛投更加稳定，抛投范围更加精准。
握持柱11底部通过销轴转动连接有支撑板18，且移动套6底部通过铰接有可伸缩支撑杆19，实现手持式和与地面接触放置两种发射方式相结合。
