Claim:
A foldable supporting framework for supporting an axial rod and a lamp by supporting posts; comprising: a retaining seat having an upper positioning sheet and a lower positioning sheet; the upper positioning sheet having an upper positioning hole and the lower positioning sheet having a lower positioning hole; one side of the retaining seat being a sealed side; a fixing threaded hole being formed on the sealed side; edges of the upper positioning sheet and lower positioning sheet near the sealed side being formed with pivotal holes; at least one movable block; the at least one movable block having a screw hole; at a portion of the at least one movable block coupled to the pivotal holes of the retaining seat having penetrating hole; a stud passing through the pivotal hole of the upper and lower positioning sheets and the penetrating hole of the at least one movable block so as to rotatably fix the at least one movable block to the upper and lower positioning sheets; thereby, the at least one movable block being movable around the stud; two supporting posts; one supporting post being locked to the fixing threaded hole of the sealed side; and the other supporting post being locked to the screw hole of the at least one movable block; thereby, the two supporting posts being locked to the sealed side and the at least one movable block wherein in use, an axial rod is inserted into the upper positioning hole and the lower positioning hole of the retaining seat, the axial rod is provided to lock other object; wherein when the at least one movable block rotates around the stud, each supporting post is expanded so that all the supporting posts are aligned to reduce the volume of the supporting framework; and wherein an inner side of a lower sheet of the at least one movable block is formed with a cambered notch; a cambered surface of the axial rod is capable of being adhered to the cambered notch so that an outer surface of the at least one movable block is at the same plane with two sides of the retaining seat.
