    摘要: An adjustable frame for jig-saw puzzles defining the exterior parameters of the puzzle. Each side of the frame is made up of two or more members connected to each other by clamps that allow linear sliding of the members so as to make the frame independently adjustable as to length and width. A base member is connected to the bottom of the frame to provide a puzzle work surface.
