The utility model relates to the technical field of unmanned aerial vehicles, in particular to a thrower applied to an unmanned aerial vehicle. The thrower applied to the unmanned aerial vehicle has the advantages that the thrower can be flexibly disassembled and assembled from the unmanned aerial vehicle to enable the unmanned aerial vehicle to have various mounting forms, so that the unmanned aerial vehicle has diversified functions, and the use cost of the unmanned aerial vehicle is reduced. The throwing device applied to the unmanned aerial vehicle comprises a first connecting piece, a second connecting piece and a throwing mechanism installed on the second connecting piece. The first connecting piece can be installed on an unmanned aerial vehicle platform, and the first connecting piece is detachably connected with the second connecting piece. When the unmanned aerial vehicle platform is used, the first connecting pieces installed on the unmanned aerial vehicle platform can be connected with the second connecting pieces carrying different throwing mechanisms, that is to say, different types of throwing mechanisms can be installed on the same unmanned aerial vehicle platform, and the functions of the unmanned aerial vehicle platform are more diversified.
