Abstract The utility model relates to a safety mechanism of a supporting frame, the side board of a pivoting seat is pivoted with a framework of a fixed seat by a mandrel; the fixed seat is provided with a bolt in a penetrating way; the tail end of the mandrel is provided with a spring fixed board; a torsion spring is sheathed in the mandrel; and the two ends of the torsion spring are respectively fixed on the side board and the spring fixed board; when the tail end of the bolt is butted with the first stopping part of the side board, the framework forms the smallest supporting angle.
