A foldable supporting framework comprises a retaining seat has an upper positioning sheet and a lower positioning sheet. At least one movable block is rotatably fixed to the upper and lower positioning sheets. There are at least two supporting posts; one supporting post being locked to the fixing threaded hole of the sealed side. Each of the other supporting posts is locked to the screw hole of a respective movable block. Thereby, at least two supporting posts are locked to the sealed side and the movable blocks. An axial rod is inserted into the upper positioning hole and the lower positioning hole of the retaining seat, and the axial rod is provided to lock other object. When the movable blocks rotate around the studs, each supporting post can be expanded so that all the supporting posts are aligned to reduce the volume of the supporting framework.
