The utility model belongs to the field of window screens, and particularly relates to a clamping and embedding type outward-opening
cantilever which comprises a main frame and a main
stile which are connected with the clamping and embedding type
cantilever to form a new structure, one side of the clamping and embedding type
cantilever is sequentially provided with a corner connector cavity, an angle assembling steel sheet groove, an
adhesive tape groove and a clamping groove, the corner connector cavity is square, the size of the angle assembling steel sheet groove is larger than that of the
adhesive tape groove, and the clamping groove is connected with the main frame. The clamping groove is located below the corner connector cavity, the clamping groove of the clamping-embedded cantilever is connected with the main frame to form a frame structure, the clamping-embedded cantilever is connected with the main
stile to form two
mullion structures, and when the clamping-embedded cantilever is installed on one side of the main
stile, the clamping-embedded cantilever is used for single-side fixing. When installed on the two sides of the main stile, the fixing device is used for fixing the two sides. A screw connection mode adopted by a traditional switching frame is replaced, and the phenomena of sealing and
water leakage at screws are avoided; and through the combination with the main frame and the main stile, the
assembly of various window types can be realized. According to the
window screen assembled by adopting the structure, the width of a visual surface is reduced, namely, the width of a decorative surface at an opening position is reduced, so that a fight looks more attractive.
