Novel stable scaffold guide rail

The utility model discloses a novel stable scaffold guide rail, and relates to the field of scaffolds. Comprising two guide rods, the two guide rods are arranged in parallel, and guide sliding grooves are formed in the front faces and the back faces of the two guide rods; the two supporting assemblies are fixedly connected between the two guide rods through mounting plates, and the mounting plates are fixedly connected with the guide rods through mounting screws; and every two connecting and fixing plates form a group, the six groups of connecting and fixing plates are fixedly connected to the opposite sides of the two guide rods correspondingly, and two auxiliary sliding grooves are symmetrically formed in the inner walls of the two sides of each of the four guide sliding grooves correspondingly. The scaffold guide rail is composed of the two guide rods, the supporting assembly is arranged between the two guide rods, and the supporting assembly can keep the stability of the whole guide rail, so that the situ
