This disclosure relates to the technical field of indoor heating devices. One embodiment of this disclosure provides a geothermal multifunctional adjustable heating device, including a mounting box, on the inner surface of which a heat exchanger is movably mounted. This disclosure utilizes a mounting box, heat exchanger, L-shaped plate, gear, and toothed plate. When the first motor starts running, the shaft and gear begin to rotate. Because the outer surfaces of the gear and the toothed plate mesh, the two toothed plates move in opposite directions under the drive of the gear.
