A folding, structure for a collapsible stroller of the present invention has a pair of pivotal connectors, a pushing handle, two front support rods, two rear support rods, a pair connecting holder blocks, a chair back frame and two connecting rods. The pivotal connectors pivot the pushing handle, the front support rods and the rear support rods. The connecting rods with one end respectively pivot to the pushing handle and the front support rods and with the other end pivot to the connecting holder blocks. The chair back frame also pivots to the connecting holder blocks. Each of the rear support rods has an obstructing protrusion and pivots the connecting holder block. Each connecting holder block has a press block, the first press bar, the second press bar, a hole, the first sloped guide surface and the second sloped guide surface. The connecting holder block is movably connected with each of the rear support rods of the stroller, the obstructing protrusion blocks and prevents the connecting holder block from sliding down for keeping the stroller extended. The press block pivoted to the connecting holder block is for pushing and making the connecting holder block slide down by means of the first press bar pushing the obstructing protrusion which is inserted into the rear support rod and projects from the hole owing to the sliding down of connecting holder block and connects to the second sloped guide surface for blocking and avoiding pushing the press block unpurposely.
