At present, pile fabrics are weaved, untwisted or fluffed, and the pile fibers on the surfaces are different in length, namely the pile fibers need to be cut to be flush by a shearing machine, and the shearing machine is textile after-finishing equipment and is one of main equipment for after-finishing of pile products. The shearing process can be generally divided into pre (initial) shearing, final (fine) shearing and fancy shearing, and is mainly determined by the type of the supporting knife. The supporting knife enables the sheared fabric to run to reach the folding angle at the tip end of the supporting knife and to generate sharp bending and turning, and the tension of the inner layer and the outer layer changes to enable the fluff fiber to vertically enter the knife edge, so that the fixed-length shearing is facilitated. The supporting knife is a base station supported during the shearing operation of the fabric, and the distance between the supporting knife tip and the shearing knife is the thickness of the sheared fabric. Generally, the supporting knife is a rigid body and has no extension scope, when a shearing machine in the conventional domestic textile after-finishing equipment shears a fabric with a raised thick edge, the edge is often easily sheared to be damaged, and no proper and effective structure is provided in the domestic equipment for solving the problem.
