The invention relates to a cantilever hanging umbrella. The cantilever hanging umbrella comprises umbrella cloth, an umbrella rod, a fixed umbrella disc with a guide sleeve, a movable umbrella disc, a plurality of umbrella ribs and supporting rods with the number corresponding to that of the umbrella ribs. One end of each umbrella rib is hinged to the fixed umbrella disc, and the other end of each umbrella rib is fixed to the edge of the umbrella cloth. One end of each supporting rod is hinged to the movable umbrella disc, and the other end of each supporting rod is hinged to the middle portion of the corresponding umbrella rib. The umbrella rod is provided with an inner rod segment and a cantilever segment, and the end of the inner rod segment and the end of the cantilever segment are hinged together. The umbrella rod penetrates the fixed umbrella disc from the guide sleeve, and the end of the inner rod segment is hinged to the movable umbrella disc. The cantilever segment is pulled out of the guide sleeve, the umbrella ribs are gradually opened, the cantilever segment swings transversely to be clamped at the end of the guide sleeve, and a locating structure that the umbrella ribs are opened in place is formed. According to the cantilever hanging umbrella, the umbrella rod is ingeniously designed to move upwards, locating and hanging umbrella suspension supporting are achieved by means of cooperation with the two-segment umbrella rod, dual purposes are achieved, the structure is greatly simplified, the overall rigidity and strength are high, and the opening and folding operation is convenient and smooth.
