This invention provides a buffer structure for a launch system mounted on a drone, comprising a drone and a buffer structure at its bottom. The buffer structure includes a buffer component 1 and a buffer component 2 slidably connected to the buffer component 1. The launch system is mounted on the buffer component 2. The buffer component 2 is connected to a rotating rod assembly, which is connected to the drone. The rotating rod assembly is also connected to an airbag buffer assembly, which is mounted on a support frame at the bottom of the drone. This invention provides a buffer structure for a launch system mounted on a drone, avoiding the problems of insufficient launch accuracy and damage to the drone caused by large recoil during launch.
