[0029] Anti-slip grooves can be provided on the bottom surface of the fixing seat 5. The anti-slip grooves can increase the friction between the bottom surface of the fixing seat 5 and the ground, effectively improving the stability during placement and avoiding sliding.

[0030] A suspension mechanism 2 is provided on the bottom surface of the drone body 1. The suspension mechanism 2 includes two groups of support rods 2015 fixed to the bottom surface of the drone body 1.

[0036] The two sets of clamping rings 207 are provided with fixed columns 208, and the inner circles of the two clamping rings 207 close to each other are fixedly connected with anti-slip pads 13, which can effectively increase the friction between the clamping rings 207 and the fixed columns 208, thereby improving the fixing effect of the camera body 6 and effectively preventing the camera body 6 from rotating during operation.

[0037] The side surfaces of the two anti-slip pads 13 that are close to each other are both provided with anti-slip grooves, which can effectively increase the friction between the anti-slip pads 13 and the fixing column 208, further improving the fixing effect.

[0038] The outer surface of the fixing column 208 is fixedly connected to the connecting plate 205 , and the front surface of the connecting plate 205 is fixedly connected to the camera body 6 .

When disassembling, it is only necessary to reverse the servo motor 202 to make the threaded rod 209 drive the screw ring 2013 to move downward, and use the movable rod 2012 to push the two groups of second linkage plates 204 through the pull plate 206. The two groups of second linkage plates 204 push the two clamping rings 207 away from each other, release the fixation of the fixed column 208, and complete the disassembly.
