The invention relates to an inflating extending arm capable of flattening and rolling, belongs to the technical field of aviation and solves the problems that an existing inflating extending arm cannot automatically restore to the original structure shape of rolling and folding after inflated to unfold, multiple folding and stretching of the inflating extending arm in the space are hard to realize, and thus application range of the inflating extending arm in a spacecraft is limited. The inflating extending arm comprises two pipe walls arranged in alignment, the front end edges and the left and the right edges of the pipe walls are adhered or thermally sealed, the surface of one of the pipe walls are transversely provided with multiple carbon fiber strips, one side surface of each carbon fiber strip is adhered to this pipe wall, and the length of each carbon fiber strip is equal to the width of the pipe wall at the adhered position. One or more than one coiled spring is longitudinally arranged on the surface of the pipe wall, one rolling shaft is transversely arranged at the front end of each coiled spring, and the rear ends of the pipe walls are closed and provided with air nozzles. The inflating extending arm is used for supporting detectors and the like.
