ABSTRACT:
An assembling structure for a magnifying glass comprises a magnifying lens element and an annular lens frame. The annular lens frame is formed with a through assembling hole and provided with a guiding portion and a stopping portion. In an inner surface of the annular lens frame is formed an engaging groove. The guiding portion and the stopping portion are located at two opposite sides of the engaging groove. The annular lens frame is made of polypropylene. After being heated, the polypropylene-made annular lens frame can be softened slightly and enhanced in terms of elasticity, so that the magnifying lens element can be placed from the guiding portion and engaged into the engaging portion. By such an arrangement, the installation of the magnifying lens element in the annular lens frame is simple, quick, labor-saving and stable.
