Cable joint pretreatment device

The invention belongs to the technical field of power cables, and particularly relates to a cable joint pretreatment device which comprises a base, the output ends of electric push rods are oppositely arranged, the output ends of the two electric push rods on the same side are fixedly connected with extrusion rods, the two extrusion rods are oppositely arranged, and the two opposite faces of the two extrusion rods are in an inward concave shape; according to the cable extrusion device, the cable is arranged between the two extrusion rods to drive the electric push rod, the two extrusion rods get close to each other and extrude the cable, and due to the fact that the two opposite faces of the two extrusion rods are in an inward concave shape, the cable can be stably arranged between the extrusion rods in the cable extrusion process, and then the bent cable is extruded and straightened; at the moment, the operator can use the art knife to move and cut along the wire, and the arm or the hand of the operator can
