The invention discloses a novel cable stripping cable. The novel cable stripping knife comprises a first fixed base and a second fixed base, wherein a first clamp is movably hinged with the two sides of the first fixed base; a second clamp is movably hinged with the two sides of the second fixed base; fixing plates are fixedly mounted on both of the two ends of the first clamp and the second clamp, and the two fixing plates are fixedly connected through fixed bolts; and clamping apparatuses are movably arranged on the surface of the first clamp, and grooves are formed in the first clamp. According to the novel cable stripping knife, the rotation of a servo motor drives an adjusting screw rod to turn so as to further drive the second clamp to move towards the first clamp; the outer insulating layer of the cable can be stripped by coordination with stripping apparatuses; meanwhile, the length of the stripping screw rod can be adjusted to be matched with the stripping scale so as to more accurately control the positions of the corresponding stripping blades, so that the stripping quality can be ensured; the cables with different thicknesses of the outer insulating layers can be well adapted; the stripping force can be mastered accurately; and the angles of the corresponding stripping blades can be controlled easily.
