[0002] With the development of the economy and the improvement of living standards, people's pursuit of quality of life is getting higher and higher. In order to meet people's needs for sunshade, rain protection, and building model buildings, many related products such as awnings have appeared in daily life. , tents, etc., but these products generally only have regular shapes or outlines, and cannot change the shape according to different user needs while completing the required functions

Model ceilings of various shapes can often be seen in cultural squares, parks and other places in many cities, but they are often preformed or constructed by a combination of a large number of rigid rods, and cannot quickly change their outlines according to different seasons and occasions to build different shapes

In addition, in terms of camouflage protection for military equipment, the existing support devices cannot adjust the camouflage shape according to changes in the surrounding landforms, thus greatly reducing the effectiveness of the equipment.
