The frame includes four edge frames; at least one pair of mutually parallel edge frames of the four edge frames are separately provided with a ripple structure. The ripple structure of the invention is similar to a telescopic ripple part of a drinking straw. The dimensions of one pair of edge frames provided with the ripple structure in the length direction can be adjusted. When the dimensions of two or more kinds of frames are different but similar, a same frame can be shared to achieve the effect of one object with multiple purposes, thereby reducing the number and development cost of special moulds, shortening the development cycle of the product, and avoiding the problem that a great deal of stagnant materials are inconveniently handled when developing single device. Thus, the aim of reducing cost is achieved.
