The energy-saving heat treatment box-type resistance furnace, through the arrangement of multiple layers of heat preservation and heat insulation materials in the energy-saving heat preservation device, can achieve heat preservation and sealing of the heat inside the heating liner, avoid rapid heat dissipation, and be more energy-saving and environmentally friendly. The power unit drives the electric telescopic rod to rotate inside the sealed bearing, so that the clamping plate at the left end of the electric telescopic rod rotates, driving the other clamping plate to rotate inside another sealed bearing through the rotating shaft, thereby driving the material between the two clamping plates to rotate, so that it is heated more evenly, further improving the heating efficiency, and being more energy-saving and environmentally friendly.
