[Advantages of the Invention] The present invention compares the conventional power enhancement fact analysis as follows: Conventional technology: 1. Conventional paper frame plates are formed by bending a plurality of plates to form a curved shape. 2, the conventional paper frame plate can only be placed in a rigid angle. 3. If the zigzag surface required for the finished paperboard product is a non-vertical angle design, the two paperboard plates will be abutted because of the necessity of being set as a bevel and a screw lock. It is difficult to achieve. The invention: 1. The invention has an innovative design of forming a plurality of grooves (15) at its bend to form a bendable gap and a spacer edge piece (16), so that the portion of the paperboard plate is directly bent to reach a use list. A piece of paperboard (1 inch) can create at least one curved configuration without the need to combine more than two paperboard plates to achieve the advantages of more convenient and efficient assembly. 2. The paper frame plate (1 〇) of the present invention has a curved portion on the other side of the groove (15) and the spacer edge piece (16), which can exhibit a circular arc shape, so that the shape of the finished product is more Jovi. 1276413 is diverse and offers consumers a more diverse range of styles to make products more competitive. 3. The paper frame plate (10) of the present invention can control the maximum bending angle of the paperboard plate by pre-planning the number or spacing of the grooves (15), and construct a non-vertical angled meandering surface. The 'finished product (as shown in Figure 10), this non-conventional paperboard board can be easily reached. The new effect that can be produced by the present invention is as follows: The bent portion of the paper frame plate (1 inch) of the present invention may also be a non-gluing method, but is used to open the paper 4 plate (10) after bending. The side surface between the different faces is fixed by the positioning member, and the bending angle of the paper frame plate is achieved.
