Plane surface planing tool

The utility model relates to a plane surface planing tool, which can combine a plurality of saw blades according to the requirement of processing area and can also change the effective planing width of the planing tool and the planeness and the smoothness of a planing surface. The plane surface planing tool comprises a plurality of saw blades and a rotating shaft, wherein the saw blades are arranged on the rotating shaft along a serrated surface in a staggered and spiral manner. The plane surface planing tool has the advantages as follows: firstly, the saw blades can be combined according to the requirement of processing area, and the effective planing width of the planing tool can be changed; secondly, the plane surface planing tool does not need to cut to and fro when processing plane surfaces with different areas, so that the time conservation and the labor conservation are achieved, the work efficiency is improved, and the planing planeness can be preventing from deviating; and thirdly, the spiral arrange
