The invention discloses a multipurpose changeable frame which comprises supporting bottom pipes, a supporting square pipe and a rear fork supporting pipe. Two groups of supporting bottom pipes are arranged in pairs; the two groups of supporting bottom pipes are symmetrically arranged; the two ends of the two groups of supporting bottom pipes are connected with a first butt joint pipe and a secondbutt joint pipe correspondingly. The axis of the first butt joint pipe and the axis of the second butt joint pipe are perpendicular to the axis of the supporting bottom pipe. The two ends of the firstbutt joint pipe and the second butt joint pipe penetrate through the two supporting bottom pipes. And the number of the supporting square pipes is two, the two supporting square pipes are arranged inpairs, the two supporting square pipes are symmetrically arranged on the first butt joint pipe, the two supporting square pipes are fixedly installed between the two supporting bottom pipes in a welding fit mode, and a steering connecting mechanism is installed at the top ends of the two supporting square pipes. According to the multipurpose changeable frame, waste of steel raw materials is reduced, manufacturing investment of welding tools and clamping dies is reduced, the multipurpose changeable frame can be recycled repeatedly, and social resources are saved.
