[0034] In order to realize the fixation of the two support parts to ensure that the support end 101 can be kept stable in the storage state and the unfolded state, please refer to Figure 1 In the embodiment, a fixing member 2 is further arranged, which is connected with the two support parts and is used to lock or unlock the relative position of the two support frames 1, so that the support end 101 can be kept stable in the storage state and the unfolded state. Moreover, the fixing member 2 is connected with the body of the unmanned aerial vehicle, and the mounting end 102 of the support frame 1 is connected with the fixing member 2, so that the support frame 1 is connected with the mounting base through the fixing member 2. The mounting base is the body part of the unmanned aerial vehicle or other aircraft.

[0035] Preferably, in the embodiment, the fixing member 2 is provided with two groups, which correspond to the two support frames 1 respectively, to ensure the stability before and after the position adjustment of the support frame 1.

[0036] In some possible embodiments, please refer to Figure 1 and Figure 2 The fixing member 2 includes a guide part 21 and two fixing parts 22. The guide part 21 is arranged to be connected with the mounting base and has a guide groove 211. The mounting end 102 of the two support parts is movably arranged in the guide groove 211 and can slide along the guide groove 211, thereby supporting the support end 101 to switch between the unfolded state and the storage state. In addition, the two fixing parts 22 are connected with the guide part 21 and the two mounting ends 102, and are used to lock or unlock the relative position of the two mounting ends 102 in the guide groove 211, so that the support end 101 can be flexibly switched between the states.

[0037] In one of the embodiments, please refer to Figures 1 to 5The guide part 21 comprises a guide rail 212 and two sliding blocks 213, and the fixing part 22 comprises a movable block 221 and a fixing rod 222.

The mounting end 102 of the two support rods 11 penetrates through the two sliding blocks 213 and the guide groove 211 and is rotationally connected with the two sliding blocks 213. When the sliding block 213 slides in the guide groove 211, the top end of the support rod 11 can slide in the guide groove 211 along with the sliding block 213, thereby enabling the support end 101 at the bottom to switch between the unfolded state and the storage state. The two movable blocks 221 are slidably arranged at the two ends of the guide groove 211 and connected with the two sliding blocks 213, respectively. The movable block 221 can slide along the guide rail 212. One side of the movable block 221 is provided with a first fixing groove 223, and the guide rail 212 is provided with a plurality of second fixing grooves 224 along the length direction. The fixing rod 222 penetrates through the first fixing groove 223 and the second fixing groove 224, so as to fix the movable block 221 and the guide rail 212 relative to each other. When it is necessary to lock the support end 101 in the unfolded state or the storage state, the movable block 221 is slid to a suitable position so that the first fixing groove 223 is aligned with the corresponding second fixing groove 224, and then the fixing rod 222 is inserted, so as to stably maintain the state of the support end 101.

[0038] It should be noted that in the present scheme, the fixing rod 222 can be a screw rod or a clamping rod. When the fixing rod 222 is a screw rod, the first fixing groove 223 is a threaded groove, and the screw rod cooperates with the threaded groove. By rotating the screw rod, the relative fixation between the movable block 221 and the guide rail 212 can be achieved. When it is necessary to unlock, the screw rod is rotated in the opposite direction and is rotated out of the threaded groove. When the fixing rod 222 is a clamping rod, the first fixing groove 223 is a clamping groove, and the clamping rod cooperates with the clamping groove. By pushing the clamping rod into the clamping groove, the relative fixation between the movable block 221 and the guide rail 212 can be achieved. When it is necessary to unlock, the clamping rod is pulled out of the clamping groove.
