A push cart comprises includes a main frame, a handle, a front support, two wheel frames, two wheels, and a retractable rod and a rear support , wherein the main frame has a pair of side rods connected with a pair of rods of the handle in a slidable manner, the center portion of the main f
A push cart comprises includes a main frame, a handle, a front support, two wheel frames, two wheels, and a retractable rod and a rear support , wherein the main frame has a pair of side rods connected with a pair of rods of the handle in a slidable manner, the center portion of the main frame is connected to each other, and the lower portion of the main frame has is connected with a the wheel frame frames and a wheel respectively the wheels . The lower respective ends portion of the main frame are is connected with respective ends sides of the front support which then meshes with the wheel frame frames . The respective lower ends of the handle are connected with one end of the retractable rod whereas the other end of the retractable rod is connected with the inner center portion of the front support, thus, support. Thus, by operating the handle, the retractable rod is linked to move which then links the front support and the wheel frame to retract or to expand.
