The docking seat 21 is fixedly connected with the outer cylinder 22 (the inner arc surface of the outer cylinder 22 is in the shape of a spline cylinder) inside. The upper side of the outer cylinder 22 is fixedly connected with the bucket-shaped containing box 23. The sliding cylinder 24 is slidably connected inside the outer cylinder 22 (the upper side of the sliding cylinder 24 is in the shape of a spline shaft, preventing the sliding cylinder 24 from idling inside the outer cylinder 22). The upper side of the sliding cylinder 24 is fixedly connected with the umbrella body 25. The upper side of the umbrella body 25 is provided with uniformly distributed pull ropes 3. The upper sides of the twelve pull ropes 3 are fixedly connected with the outer surface of one top head 29 (the length of the inner six pull ropes 3 is shorter than that of the outer six pull ropes 3). The upper surface of the sliding cylinder 24 is provided with the top opening 28. The inside of the top opening 28 is slidably connected with the lower side of the outer arc surface of the top head 29. The quick response mechanism 2 further comprises a top abutment column 26 and a powder containing opening 27. The top abutment column 26 is fixedly connected to the middle part of the upper side wall of the docking seat 21.

The upper surface of the top abutment column 26 is provided with the powder containing opening 27. The inside of the powder containing opening 27 contains a small amount of gunpowder. The upper side of the outer cylinder 22 is provided with a limiting block. The upper side of the bucket-shaped containing box 23 is buckled with a buckle cover 4. The buckling force of the buckle cover 4 limits the vertical movement distance of the sliding cylinder 24, preventing the gunpowder in the powder containing opening 27 from leaking. When using the parachute safety device, the umbrella body 25 is arranged and placed inside the bucket-shaped containing box 23. Then the top head 29 is inserted into the top opening 28. Subsequently, the buckle cover 4 can be closed to achieve sealing. At this time, the gunpowder explodes instantaneously, generating an impact force. The impact force quickly upwardly impacts the sliding cylinder 24 to move upwardly by a specified distance. The limiting block prevents the sliding cylinder 24 from falling off. At this time, the top head 29 will open the buckle cover 4. After the top head 29 opens the buckle cover 4, it continues to move upwardly and will pull the umbrella body 25 to open through the pull ropes 3. At this time, the umbrella body 25 is subjected to air resistance and slows down the descending speed of the unmanned aerial vehicle, preventing the unmanned aerial vehicle from crashing.
