[0033] Working principle: Before the device starts working, the operator removes multiple U-shaped frames 4, inserts the first T-shaped block 7 at the top of the U-shaped frame 4 into the adjacent first T-shaped groove 30, and continues to move the first T-shaped block 7 to the threaded rod 28. The motor 26, a servo motor, is then started, driving the threaded rod 28 to rotate. The threaded rod 28 moves the first T-shaped block 7 through the threaded hole inside the first T-shaped block 7, thus limiting the movement of the first T-shaped block 7. The second spring 19 between the two first T-shaped blocks 7 is compressed, and the first T-shaped block 7 is driven by the rope 6. The U-shaped frame 4 moves, and the U-shaped frame 4 drives the movable frame 5 to move via the crossbar 14. When the U-shaped frame 4 and the movable frame 5 reach the desired position, the first bolt 13 is rotated to remove it from inside the movable frame 5 and the second movable plate 9. The swing angle of the first movable plate 8 and the second movable plate 9 is adjusted to expose the top of the U-shaped frame 4 and the movable frame 5, allowing goods to be placed inside. When the goods are large, the movable frame 5 is moved, which drives the crossbar 14 to move. The crossbar 14 drives the fixed plate 15 to move, and the fixed plate 15 compresses the first spring 16. Since the fixed plate 15 is located inside the cavity 32, and the diameter of the fixed plate 15 is larger than the diameter of the connecting hole 33, the fixed plate 15 will not detach from the U-shaped frame 4, thus limiting the movement of the movable frame 5. When the movable frame 5 moves, it will drive the first movable plate 8 and the second movable plate 9 to move. When the movable frame 5 moves to a distance where it can load goods, the first movable plate 8 and the second movable plate 9 are returned to a horizontal state, and the threaded hole on the second movable plate 9 is aligned with the threaded hole on the top of the adjacent movable frame 5. The first bolt 13 is threaded through the threaded hole on the second movable plate 9 and the threaded hole on the top of the movable frame 5. The perforated holes further limit the movement of the movable frame 5. Then, the elastic plate 12 is pressed down and the counterweight 10 is taken out. The counterweight 10 drives the second T-shaped block 17 to move. The second T-shaped block 17 is moved into the second T-shaped groove 29 at the bottom of the U-shaped frame 4. The elastic plate 12 is released and covers one side of the second T-shaped groove 29. The second bolt 18 is taken out and rotated to the threaded hole on the elastic plate 12 and the threaded hole on the U-shaped frame 4. If the drone is used for agriculture, the flip plate 25 is opened and fertilizer or water is put into the collection box 20. Then the drone body 1 can be started.

[0034] The unmanned aerial vehicle body 1 drives the device at the bottom to move, when moving to the position where the goods need to be dropped, if the goods inside the U-shaped frame 4 and the movable frame 5 need to be dropped, first align the center of the bottom of the unmanned aerial vehicle body 1 with the position where the goods need to be dropped, and start one of the motors 26, drive the threaded rod 28 to reverse, drive the first T-shaped block 7 to move towards the fixed column 2, until the two first T-shaped blocks 7 are away from the surface of the threaded rod 28, the first T-shaped block 7 moves through the inclined section of the middle section of the cross plate 3, and the U-shaped frame 4, the movable frame 5 and the weight of the goods quickly move downwards, after the first T-shaped block 7 is separated from the first T-shaped groove 30, it will enter the groove 31, when the two first T-shaped blocks 7 are located in the groove 31, the U-shaped frame 4, the movable frame 5 and the goods will move downwards, the counterweight 10 ensures that the U-shaped frame 4 and the movable frame 5 remain stable when moving downwards and will not overturn, the air bag 11 is provided to have a buffering effect, ensuring the integrity of the goods, when the fertilizer or water inside the collecting frame 20 needs to be discharged and dropped, start the pump 21, the pump 21 absorbs the fertilizer or water inside the collecting frame 20 through the vertical pipe 22 and delivers it to the connecting pipe 23, and then discharges it through the discharge cover 24, the battery installed at the bottom of the cross plate 3 can supply power to the motor 26 and the pump 21 for continuous operation.
