Dismantle to brace 7, telescopic part 6 will order about stock 8 and rotate and stretch into to holding tank 4 in for the lower surface of flight body 1 is clean and tidy relatively, and at this moment, support piece 3 is in the state of accomodating.

When using the aircraft, through on-the-spot personnel gripping quarter butt 9 drive two stock 8 relative rotations and keep away from flight body 1, then will support vaulting pole 7 detachable and connect between quarter butt 9 and extensible part 6 for support vaulting pole 7 restriction bracing frame 5 rotates and is close to flight body 1, and at this moment, support piece 3 is in the expansion state. When the support 3 is in the rotated-open state, the end of the long rod 8 facing away from the rotating part and the short rod are both lower than the bottom end of the photographing device 2.

Referring to fig. 3 and 4, the extensible member 6 includes a mounting case 12, a rotation shaft 13, an elastic steel tape 14, and a pull cord 15. The mounting box 12 is fitted in the housing groove 4 and located on the side of the rotating portion away from the photographing device 2. The lower surface of mounting box 12 and the top cell wall parallel and level of holding tank 4, the vertical link up of lower surface of mounting box 12 has seted up one and has dodged hole 16, and the downthehole wall of dodging hole 16 is seted up there is the internal thread.

The rotating shaft 13 horizontally penetrates through the mounting box 12, the rotating shaft 13 is parallel to the photographic device 2, and the rotating shaft 13 is relatively rotatably connected in the mounting box 12.

One end of the elastic steel winding belt 14 is fixedly connected to the rotating shaft 13, and the other opposite end is wound around and connected to the rotating shaft 13 and fixedly connected to one end of the pulling rope 15. One end of the pull rope 15, which is far away from the elastic steel winding belt 14, passes through the avoidance hole 16 and is fixedly connected to the middle of the short rod 9 in the length direction.

Referring to fig. 4 and 5, a binding groove 24 is correspondingly formed in the middle of the short rod 9, one end of the pull rope 15, which deviates from the elastic steel winding 14, is bound to form a sleeve ring, the sleeve ring is sleeved on the binding groove 24, and the binding groove 24 limits the axial movement of the pull rope 15 along the short rod 9. Still the flexible buffering sponge cover 17 of fixedly connected with on the lateral wall of quarter butt 9 to when flight body 1 descends or when the bracing frame 5 rotates and is close to in the holding tank 4, through the elastic deformation of buffering sponge cover 17, absorb partial kinetic energy, reduce flight body 1 and descend or bracing frame 5 rotates and is close to the produced vibration of holding tank 4 time.

Referring to fig. 4 and 6, the axis of the support rod 7 is hollow and through, the diameter of the outer side wall of the support rod 7 is b, a through groove 23 is formed in the peripheral side wall of the support rod 7, and the through groove 23 is arranged along the length direction of the support rod 7.
