The guide element is provided with a guide slope surface extending towards the radial outer side of the wire harness, and the guide slope surface is inserted into and acts on an interface between the braid layer and the insulating layer; an active deformation strategy of internal pressure and external expansion is adopted: a clamping and pressing piece acts on the inner side of the end part of the wire harness, and uniform pressure is applied to the center along the radial direction, so that an original circular section generates controllable local elliptical or flattened deformation.
