The cooperation of the guide slider and the guide chute can guide the reset plate 208 to make the movement of the reset plate 208 stable. The fit between the groove and the connecting block 204 can increase the stability of the connecting block 204.

[0036] Embodiment 2:

[0037] Refer to Figure 1 ,Figure 3 and Figure 6 , a buffer mechanism 3 is provided at the bottom of the pallet 202. The buffer mechanism 3 includes a buffer box 301. The buffer box 301 is fixedly connected to the pallet 202. A first spring 302 is fixedly installed at the top of the inner cavity of the buffer box 301. One end of the first spring 302 is fixedly installed with a first movable plate 303. A positioning plate 306 is fixedly installed in the inner cavity of the buffer box 301. A diversion groove 307 is formed in the inner cavity of the positioning plate 306. A second spring 309 is fixedly installed at the bottom of the inner cavity of the buffer box 301. One end of the second spring 309 is fixedly installed with a second movable plate 308. Hydraulic oil 312 is provided between the second movable plate 308 and the first movable plate 303. A positioning rod 310 is fixedly installed at the bottom of the second movable plate 308. The bottom of the positioning rod 310 is fixedly installed with a grounding support frame 311. A guide rod 304 is fixedly installed at the top of the inner cavity of the buffer box 301. A guide ring 305 is fixedly installed at the top of the first movable plate 303 through a bracket. The guide rod 304 is slidably connected to the guide ring 305. The grounding support frame 311 is a stainless steel support frame, and a rubber pad is fixedly installed at one end of the grounding support frame 311.

[0038] In this embodiment: By providing the buffer mechanism 3, when the grounding support frame 311 is stressed, the hydraulic oil 312 can be pressurized by the second movable plate 308. Through the cooperation of the first spring 302, the first movable plate 303, the second movable plate 308 and the second spring 309, the impact force during landing can be buffered.

The rubber pad can increase the buffering performance.

[0039] The implementation principle of the present utility model is as follows: When in use, bolts are inserted into the mounting holes, and the mounting plate 1 can be fixed to the bottom of the drone. Pull the pull ring 210 to drive the insertion rod 209 to move. The insertion rod 209 drives the reset plate 208 to move, and the reset plate 208 compresses the reset spring 207. At this time, the insertion rod 209 disengages from the insertion hole 205 on the side of the connection block 204, facilitating the removal of the support plate 202, thereby facilitating the maintenance of the buffer mechanism 3. Release the pull ring 210, and the reset spring 207 rebounds to drive the reset plate 208 and the insertion rod 209 back to their original positions. The insertion rod 209 is inserted into the insertion hole 205 on the side of the connection block 204, which can stabilize the connection block 204, thereby stabilizing the buffer mechanism 3. After the drone lands, the grounding support frame 311 contacts the ground, and the grounding support frame 311 exerts pressure on the positioning rod 310. The positioning rod 310 exerts pressure on the second movable plate 308. At this time, the second spring 309 is stretched, and the potential energy of the second spring 309 can buffer the impact force. The second movable plate 308 exerts pressure on the hydraulic oil 312, and the hydraulic oil 312 flows upward along the diversion groove 307. The hydraulic oil 312 exerts pressure on the first movable plate 303, and the first spring 302 can further buffer the impact force. Due to the action of the hydraulic oil 312, the first spring 302 and the second spring 309 slowly return to their original shapes, avoiding the drone from tipping over due to repeated rebounds.

[0040] The above are all the preferred embodiments of the present utility model, and the protection scope of the present utility model is not limited thereby. Therefore, all equivalent changes made according to the structure, shape, and principle of the present utility model should be covered within the protection scope of the present utility model.
