The invention belongs to the field of wood and plastic rails and particularly relates to a rail convenient to adjust and high in universality. The rail convenient to adjust and high in universality comprises a base, a stand column and a rail plate, wherein the stand column comprises an inner casing pipe and an outer wall pipe which is provided with one or more mounting grooves, and locating grooves are formed in the groove walls of the mounting grooves. The rail further comprises a sealing strip which is provided with matching ribs, wherein the locating grooves are formed in the sides, close to groove openings, of the groove walls of the mounting grooves, and the outer wall pipe is fixedly connected with the inner casing pipe through the groove walls of the mounting grooves. The inner casing pipe is a square pipe, a circular pipe is arranged on the inner pipe wall of the inner casing pipe in an internally tangent mode, locating cavities are formed in the parts, located at the four corners of the inner casing pipe, between the circular pipe and the inner casing pipe, and the base comprises a bottom plate and a locating pipe and is further provided with locating bars. The rail convenient to adjust and high in universality is simple in structure, good in mounting stability, not prone to shaking, high in universality of all parts, convenient to process, low in cost and small in mounting waste, and the mounted wood and plastic rail is high in integrality, high in universality of parts and convenient to adjust.
