ABSTRACT:
A foldable frame assembly includes a base frame having a wheel-carrying end for mounting a wheel unit, a handgrip end, and an intermediate portion connected to a prop member so as to lift the base frame to a standing position. A tabletop has a front tabletop end pivoted to the intermediate portion for suspending a machine above the ground surface so as to enable a rear tabletop end to turn from a working position to a folded position. A bracing member has an anchoring end pivotally mounted on the wheel-carrying end, and a slidable end coupled with the rear tabletop end such that when the rear tabletop end is turned from the working position to the folded position, the slidable end is turned to be close to the intermediate portion. A rear locking unit is disposed to guard against movement of the slidable end.
