The invention discloses a multi-function rebar stable transport cart, and belongs to the technical field of transportation equipment. The multi-function rebar stable transport cart comprises two setsof supporting base plates and the two sets of suporting base plates are arranged in parallel front and back. Installing bases are arranged at the top centres of the supporting base plates. Inner chambers of the installing bases are fixedly provided with supporting stand columns through fastening screws. Positioning screw holes are uniformly formed in the outer walls of the supporting stand columns. According to the invention, rebars are placed at the tops of supporting side plates, and according to the arrangement of limit stop rods, the sliding of the rebars which are placed on the supportingside plates is limited, and thus the danger of rebars from sliding down during transportation is prevented. Positions of positioning supporting seats on the supporting stand columns are adjusted, andthe transport carrying capacity is convenient to adjust, and accordingly transportation of different specifications of the rebars is convenient to carry out. The position of an insert plate in a stable sleeve is adjusted, and the adjustment of the transportation length is convenient to carry out, and accordingly the transportation of different lengths of the rebars is convenient to carry out.
