Wire tightener for electric power engineering cable installation

The invention belongs to the technical field of cable installation, and particularly discloses an electric power engineering cable installation tightener which comprises a supporting plate, an installation mechanism is arranged at the bottom of the supporting plate, sliding seats are symmetrically connected to the two sides of the middle of the supporting plate, and a cable winding assembly capable of winding a cable in an S shape is arranged above the sliding seats. The winding assembly comprises two symmetrically-arranged fan-shaped winding frames, a plurality of outer guide wheels are rotationally installed on the arc-shaped faces of the outer side edges of the fan-shaped winding frames at equal intervals, inner guide wheels are rotationally installed on the outer sides of the included angles, away from the arc-shaped faces, of the fan-shaped winding frames correspondingly, and the fan-shaped winding frames are connected with the adjacent sliding bases through driving parts. A linkage piece is arranged bet
