[0025] like Figure 7 The centering process is shown below: the lifting platform rises to the designated position, the system issues a command, and the centering bar at this position can push the drone's tripod.

[0026] Upon receiving the command, the X-direction centering component operates as follows: Stepper motor 8-1 drives the first transmission shaft 9 to rotate via synchronous pulley 8-3, synchronous belt 8-5, and synchronous pulley 8-6 on the transmission shaft. The first transmission shaft 9 drives the synchronous pulleys 10 at both ends, which in turn drive the 32-tooth synchronous pulley 11-7 and 48-tooth synchronous pulley 11-8 to rotate via synchronous pulley and synchronous belt 11-6. At this time, the first synchronous belt 12 moves, causing the first centering strip mounting plate 3, which is fixed on the first synchronous belt 12, to move. The first centering strip mounting plate 3 is fixed at the upper and lower ends of the first synchronous belt 12 and is also fixed on the first linear guide rail 2 to ensure that the first centering strip mounting plate 3 runs smoothly when moving left and right.

At this time, the second synchronous belt 20 moves, causing the second centering strip mounting plate 16, which is fixed on the second synchronous belt 20, to move.

At this time, the short-direction centering strip 18 can center the UAV that has landed on the landing pad to the center of the platform.

[0028] like Figure 8 The propeller-shifting process is as follows: After centering, the lifting platform descends to the designated position. The system issues a command, and the middle position of the propeller lever 7 on the long-direction centering bar 5 corresponds to the height of the UAV propeller blades. Upon receiving the command: The X-direction centering component operates. The stepper motor 8-1 drives the first transmission shaft 9 to rotate via the motor end synchronous pulley 8-3, the synchronous belt 8-5, and the transmission shaft synchronous pulley 8-6. The first transmission shaft 9 drives the synchronous pulleys 10 at both ends, which in turn drive the 32-tooth synchronous pulley 11-7 and the 48-tooth synchronous pulley 11-8 to rotate via the synchronous pulleys and synchronous belt 11-6. At this time, the first synchronous belt 12 moves, causing the first centering bar mounting plate 3 fixed on the first synchronous belt 12 to move. The first centering bar mounting plate 3 drives the long-direction centering bar 5 to move, and the propeller lever 7 on the long-direction centering bar 5 moves the UAV propeller blades into the nest.
