摘要： A rotary extending frame includes a frame, a handle, a plurality of friction pieces, and a plurality of positioning discs. The frame has a plurality of accommodation spaces and fastening portions. The handle is rotatably disposed on the frame and has a holding portion and a plurality of rotating portions connected to two ends of the holding portion and facing two side surfaces of the frame respectively. The friction pieces are disposed on the corresponding rotating portions respectively and are firmly attached on the two side surfaces. The positioning discs are disposed on the corresponding rotating portions respectively and are pivotally connected to the friction pieces. The friction pieces and the frame clamp the corresponding rotating portions, so that the rotating portions and the positioning discs are adapted to rotate relative to the friction pieces and the frame and rub against the corresponding friction pieces simultaneously.
