Edge trimming shear device of tension leveler

The invention discloses an edge trimming shear device of a tension leveler, which comprises an edge trimming shear box body, and further comprises a laterally pressing roller frame, a roller frame, a laterally pressing roller, and a driving device, wherein the laterally pressing roller frame is hinged with the edge trimming shear box body; the roller frame is distributed on the laterally pressing roller frame; the laterally pressing roller frame is rotatablely arranged on the roller frame; and driving device is used for driving the laterally pressing roller to rotate around a hinge point hinged with the edge trimming shear box body. When in work, the driving device drives the laterally pressing roller to rotate around the hinge point so as to enable the roller frame distributed on the laterally pressing roller frame to move up and down, so as to drive the laterally pressing roller to move up and down. When being needed, the laterally pressing roller frame is enabled to move up and down around the hinge point,
