[0002] Rural ecological landscape refers to the landscape with ecological functions and aesthetic values ​​that is jointly constructed by natural and artificial means in rural areas. This kind of landscape can not only provide beautiful visual enjoyment, but also promote biodiversity, improve the ecological environment, and enhance the quality of life of residents. At present, the setting of rural ecological landscape is mostly done by planting devices, which are set up on the roadside or fixed places in the countryside.

[0003] Existing patent CN202310447921.1 discloses a green belt for road ecological landscape and a method of use, including a box, and bottom plates are fixedly installed on both sides of the box. The present invention can realize the protection of plants by the outer frame and inner frame that can cooperate with the screw rod to rotate and drive the rising when strong winds come, so as to prevent the plants from being broken or folded by strong winds. The first and second horizontal openings are set to allow the wind from the outside to pass through, thereby reducing the pressure caused by the strong wind blowing the outer frame, and then reducing the resistance of the outer frame and the side panels when they rise, so that the outer frame can rise more easily and reduce the loss caused to the screw rod.
