• a frame structure, comprising a main frame, at least two auxiliary frames and multiple sub-frames, a middle of each auxiliary frame being respectively rotatably connected to two ends of the main frame, a middle of each sub-frame being respectively loosely connected to two ends of each auxiliary frame, and the sub-frame located outmost and each auxiliary frame both being formed with a round inserting hole at a center;
• a squeegee, connected to each sub-frame;
• and
• a decorative cover structure, comprising a main cover, at least two auxiliary covers and at least two sub-covers, the main cover covering the main frame, each auxiliary cover covering each auxiliary frame, each sub-cover covering part of each sub-frame, each auxiliary cover comprising an inserting bar protruded therefrom and correspondingly inserted into the inserting hole of each auxiliary frame, and each sub-cover comprising an inserting bar protruded therefrom and correspondingly inserted into the inserting hole of the sub-frame located outmost,
• wherein the inserting bar of each auxiliary cover and the inserting bar of each sub-cover are respectively a hollow round column comprising a hollow portion therein, an end of each inserting bar comprises a flange protruded from a periphery thereof and an opening communicated to the corresponding hollow portion;
• wherein the main frame, the auxiliary frames and the sub-frames are non-connected with each other;
• wherein before each inserting bar inserts into each round inserting hole, an outer diameter of each inserting bar is slightly greater than an inner diameter of each round inserting hole;
• wherein while each inserting bar inserts into each round inserting hole, each inserting bar is elastically compressed through each hollow portion and each opening along a radial direction, so as to be tightly inserted into and circumferentially contacted each round inserting hole, and the flange of each inserting bar reversely fasten the auxiliary frame and the sub-frame at the round inserting hole corresponding thereto;
• wherein each inserting bar comprises a rod plug comprising a plug portion and a cap portion, the plug portion is correspondingly inserted and plugged into the hollow portion to tightly fix the inserting bar in the round inserting hole, and the cap portion clamps and fixes the flange with the corresponding auxiliary cover or the corresponding sub-cover.
