The guide block 9 moves on the guide rod 8, and the spring 10 can stretch and contract the guide block 9, so that the limit block 11 fits with the suspension member 6; the decoupling mechanism further includes a second driving motor 12 detachably arranged inside the decoupling seat 5, a support member 13 detachably connected to the output shaft of the second driving motor 12, and a fixing component for fixedly connecting the support member 13 and the second driving motor 12. The second driving motor 12 can control the rotation of the support member 13, so that the support member 13 can be connected to the suspension member 6; a support groove 14 matching the suspension member 6 is formed on the support member 13. The second driving motor 12 controls the rotation of the support member 13 to support or separate the suspension member 6. Start the first driving motor 7 to drive the suspension member 6 to rotate, place the connection belt 4 on the suspension member 6, so that the limit block 11 drives the guide block 9 to move on the guide rod 8, and then the limit block 11 limits the connection belt 4.

[0027] Several groups of first grooves matching the guide rod 8 are formed inside the decoupling seat 5. Both the upper and lower end surfaces of the guide block 9 are connected to the spring 10 sleeved on the guide rod 8.

[0032] On the inner side wall of the decoupling seat 5, several groups of rotating grooves matching the suspension member 6 are provided. In the rotating grooves, a rotating block 26 detachably connected to the suspension member 6 is rotatably arranged. A rotating rod 27 is vertically installed between two groups of rotating blocks 26. The output shaft of the first driving motor 7 penetrates through one side surface of the decoupling seat 5 and is detachably connected to the rotating shaft of the rotating block 26. The first driving motor 7 drives the two groups of rotating blocks 26 to rotate through the rotating rod 27. When the first driving motor 7 is started, the rotating block 26 is driven to rotate. The rotating block 26 drives the other rotating block 26 to rotate through the rotating rod 27. The rotating block 26 drives the suspension member 6 to rotate. When the first driving motor 7 rotates forward, the suspension member 6 rotates upward, and the connecting belt 4 can be suspended. When the first driving motor 7 rotates in reverse, the suspension member 6 rotates downward, and the connecting belt 4 can be decoupled and released.

[0033] One end of the rotating block 26 is vertically provided with a mounting block 28. On one end face of the suspension member 6, a mounting groove matching the mounting block 28 is provided. On the decoupling seat 5, a rotating hole corresponding to the rotating rod 27 is provided. The rotating block 26 can be disassembled and replaced through the mounting block 28.

On the bottom end face of the limiting block 11, an anti-sliding block 29 matching the connecting belt 4 is provided. The anti-sliding block 29 can improve the connection stability between the connecting belt 4 and the suspension member 6.

[0035] On the bottom end face of the decoupling seat 5, several groups of height-adjustable support feet 2 are detachably installed. The support feet 2 prevent the decoupling seat 5 from directly contacting the ground. For this UAV with a decoupling and release device, the first driving motor 7 is started to drive the suspension member 6 to rotate. The connecting belt 4 is placed on the suspension member 6, so that the limiting block 11 drives the guiding block 9 to move on the guiding rod 8. Then, the limiting block 11 limits the connecting belt 4. The second driving motor 12 is started to drive the supporting member 13 to rotate to the position of the suspension member 6, so that the suspension member 6 is connected to the supporting groove 14, and the supporting member 13 supports the suspension member 6; The limiting block 11 is moved to drive the strengthening block 15 to move. The strengthening block 15 drives the guiding block 9 to move on the guiding rod 8, so that the guiding block 9 drives the spring 10 to expand and contract; Start the second drive motor 12. When the second drive motor 12 rotates forward, it drives the first fixed seat 17 to rotate. The first fixed seat 17 drives the reinforcement block 19 to rotate through the first fixing member 18, and the reinforcement block 19 drives the support member 13 to rotate, so that the support member 13 approaches the suspension member 6, connects the suspension member 6 with the support groove 14, and supports the suspension member 6. When the second drive motor 12 rotates reversely, the support member 13 is separated from the suspension member 6, and the suspension member 6 is removed from the support groove 14, facilitating the suspension member 6 to release the connecting belt 4; Remove the fixing rod 25 from the fixing hole and remove the second fixing member 23 from the second fixing groove, so that the second fixing member 23 is disassembled and separated from the second fixed seat 24, and the support member 13 is disassembled and separated from the second fixing member 23; Start the first drive motor 7 to drive the rotating block 26 to rotate. The rotating block 26 drives another rotating block 26 to rotate through the rotating rod 27, and the rotating block 26 drives the suspension member 6 to rotate. When the first drive motor 7 rotates forward, the suspension member 6 rotates upward and can suspend the connecting belt 4. When the first drive motor 7 rotates reversely, the suspension member 6 rotates downward to unhook and release the connecting belt 4. For the UAV with a decoupling and releasing device, through the decoupling mechanism on the UAV main body 1 provided, the first drive motor 7, the suspension member 6 and the rotating block 26 can cooperate to transport the transportation material box 3 through the connecting belt 4. The limiting block 11, the guide rod 8, the guide block 9 and the spring 10 cooperate to improve the connection stability between the suspension member 6 and the connecting belt 4. The second drive motor 12 and the support member 13 cooperate to improve the bearing capacity of the suspension member 6.
