A supporting and steering support wheel capable of ascending and descending is characterized by comprising a barrel, a movable rotating and bearing device, a connecting plate, a pulley and a lifting device. According to the supporting and steering support wheel capable of ascending and descending, the lifting device is adopted and internally provided with a gear seat, a bevel gear, a flat key and a threaded rod; the height of the support wheel can be adjusted by hand-cranking the bevel gear, so the effect of use convenience is achieved; heavy-duty tapered roller bearings are adopted in the movable rotating and bearing device, so the overall bearing capacity of the support wheel is improved; the connecting plate is provided with a movable pin shaft and a limiting hole so that the support wheel can be rotated and folded through a fixed pin shaft, and the effect of use convenience is achieved; meanwhile, a supporting tube is provided with a mounting plate and bolts, so the support wheel can be installed more conveniently, and the installation time is shortened; besides, the pulley is a solid cast iron pulley, the problem of tire burst due to an overload will not occur, and therefore the service life of the support wheel is prolonged.
