The invention relates to the technical field of mechanical trolleys, in particular to an unpowered mechanical trolley which comprises a supporting frame, a supporting frame is arranged above the supporting frame, a square plate is fixed in the supporting frame, rollers are rotatably arranged on the surface of the square plate, a top column is fixedly connected to the bottom of the square plate, the bottom of the top column is fixedly connected to a connecting plate, and the connecting plate is arranged on a lifting table. A spline shaft is fixed to the center of the bottom of the lifting table, lower supports are arranged at the bottoms of the two sides of the connecting plate, a supporting seat is arranged on the surface of the carrying plate, the interior of the supporting seat is hollow, a spline sleeve is rotationally arranged above the supporting seat, the spline shaft is matched with the spline sleeve, and a driven bevel gear is fixed to the outer side of the top of the spline sleeve. The trolley has the beneficial effects that the trolley does not need to be driven by an external energy source, and goods are conveyed by skillfully utilizing the gravity of the goods and the elastic force of the spring, so that the energy consumption is effectively reduced, and the energy utilization efficiency is improved.
