[0025] The specific implementation method is as follows: by setting up the retractable and deployable assembly 8, the screw 808 is adjusted to move through the screw seat 807, the movable frame 9 and the bracket 5. At the same time, the movable frame 9 drives multiple movable frames 9 to be evenly deployed to one side through the linkage effect between the third connecting rod 804 and multiple second connecting rods 802, so that the multiple movable frames 9 and the bracket 5 are moved, and the rain shielding film 6 is deployed to a suitable position, so as to meet the rain shielding requirements of cherry trees planted in different numbers, so that the rain shielding film 6 can be suitable for different application scenarios.
