[0002] Built-in blinds are a common type of blinds. They are a combination of traditional windows and blinds, making them more convenient to use. Corner pieces are one of the essential parts of built-in blinds. They not only connect the window frame, but also fix the lifting guide wheel and the flip wheel. At present, corner pieces generally adopt an integrated right-angle structure. During the assembly process of built-in blinds, it is necessary to first assemble the supporting seat of the corner piece and the lifting guide wheel with the flip wheel, and then respectively pass the traction rope and the flip rope on the lifting guide wheel and the flip wheel, and finally fix the corner piece to the window frame. However, due to the small size of the corner piece, the lifting guide wheel and the flip wheel are close to each other, which not only increases the difficulty of installing the lifting guide wheel and the flip wheel, but also the traction rope and the flip rope will inevitably interfere with each other when passing, thereby affecting the assembly efficiency of the corner piece.

[0003] In view of the above situation, it is necessary to design a corner assembly of a built-in blind that can reduce the difficulty of installing the lifting guide wheel and the flip wheel and prevent the traction rope and the flip rope from interfering with each other when they are installed. To this end, the applicant has made a useful design, and the technical solution to be introduced below is produced under this background. Summary of the invention
