The utility model provides an it is deployable for single paper of spatial structure binding structure of binding into book form, it includes the binding paper body of being made by the sheet -fed. Binding the paper body and including a plurality of folding paper, arbitrary adjacent two all are provided with folding position between folding paper. Fold paper along folding position when folding in proper order when a plurality of, bind the paper body and form the binder structure, fold paper when expanding in proper order along folding position when a plurality of, bind the paper body and form planar structure. This binding structure can realize single paper and bind into book form and expand to expand back paper non -deformable, the next page page or leaf of can realizing binding into book form is opened, and simple structure, can take down the exhibits in a flexible way, very practical, the in -process of binding into book form need not the mucilage binding or binds with appurtenance, and is very convenient. In addition, can install three -dimensional scene structure additional, can single page after folding read three -dimensional scene, also can form a big complete three -dimensional scene after the expansion to read, show and propaganda, accord with user's demand, strengthened interestingly and ornamental.
