During the prefabrication process of the stairs, a mold needs to be built. The mold in the existing technology is single and cannot adjust the height and angle of the prefabricated stair tread mold. After the base plate is built, the size of each ladder can only be adjusted by manually moving the template. There are adjustment errors during the adjustment process, and the adjustment is inconvenient. They need to be moved one by one, which is not conducive to improving production efficiency and the size progress of the prefabricated stair treads. Summary of the invention
