description The invention discloses a variable diameter mould for processing a spiral stirrup, and belongs to the technical field of spiral stirrup processing and manufacturing. The variable diameter mould for processing the spiral stirrup is mainly provided with a pivot shaft and a plurality of peripheral rods arranged in the circumferential direction of the pivot shaft at intervals uniformly, wherein with rotation of the pivot shaft around the axis of the pivot shaft in one direction, a first movable nut and a second movable nut which are in threaded connection with the periphery of the pivot shaft canbe moved towards each other or away from each other, so that the angles of first radial rods and second radial rods are changed; and accordingly the distance between the pivot shaft and the peripheralrods in the radial direction of the pivot shaft is changed. When an imaginary circle defined by the peripheral surfaces of the sides, far away from the pivot shaft, of the peripheral rods is consistent with the inner diameter
