When the synchronous wheel 901 and the synchronous belt 902 rotate, the two sets of screw rods 5 rotate and drive the supporting platform 6 to descend. When it descends to a certain height, the baffle 16 on one side of the supporting platform 6 is rotated and the base 7 with the plant protection drone is pulled out through the pulley 18 at its bottom. The plant protection UAV is operated at the designated position; when the plant protection UAV is completed, it is placed on the base 7, and at the same time, the base 7 is slid into the carrier 6 along the limit steps 15 on both sides of the carrier 6 and the baffle 16 on one side of the carrier 6 is closed, and then the drive motor 903 is started and reversed. The drive motor 903 reverses to drive the screw rod 5 and the carrier 6 connected to the screw rod 5 to rise.
