Chamfering tool for outer semi-conductive layer of cable

The invention discloses a cable outer semi-conductive layer chamfering tool which comprises a cutting part used for chamfering a cable outer semi-conductive layer and a fixing part used for being installed on the cable outer semi-conductive layer. The cutting piece comprises an arc-shaped sleeve and an arc-shaped horn mouth, the arc-shaped sleeve is used for sleeving the main insulation of the cable, the arc-shaped horn mouth is used for being matched with the fixing piece to limit the cutting distance of the cutting piece, and the arc-shaped horn mouth is arranged on one axial side of the arc-shaped sleeve; a first chamfering knife edge and a second chamfering knife edge which are used for chamfering cutting are arranged at the two ends of the arc of the arc-shaped horn mouth correspondingly. The outer semi-conductive layer chamfering device can effectively solve the problem that the outer semi-conductive layer chamfering manufacturing quality is limited by the technical level of constructors, meanwhile, ope
