The two sides of the driving roller are rotated and installed on the inner walls on both sides of the installation frame. The inner walls on both sides of the installation frame are provided with limiting waist-shaped holes. Perpendicular to the driving roller, the rotating shaft is erected on the limiting waist-shaped holes on the inner walls of both sides of the installation frame, and fastened by bolts, the rotating shaft is parallel to the driving roller, and the driven rotating roller The roller is rotatably installed on the rotating shaft, the two sides of the driving roller are equipped with the hand crank, the adjustment device includes an adjustment bolt, and the bottom end of the installation frame is provided with a threaded hole that cooperates with the adjustment bolt , the threaded hole communicates with the limiting waist-shaped hole, and the central axis of the threaded hole coincides with the centerline of the limiting waist-shaped hole, and the adjusting bolt passes through the threaded hole and abuts against the rotating shaft.

Further, the driving roller is provided with a first concave groove, the surface of the first concave groove is provided with a first rubber protrusion to improve friction, and the driven roller is provided with the first concave groove. The matched second concave groove, the second concave groove is provided with a second rubber protrusion to improve friction.

The utility model provides a power transmission line tensioner suitable for various types, which has a simple and reasonable structure. When in use, the installation frame is directly fixed on the power pole tower, and the power transmission line is stretched to the driving roller and from the Between the moving rollers, adjust the adjusting bolt so that the driving roller and the driven roller tightly clamp the power transmission line, and then fix the rotating shaft, and then turn the driving roller and the driven roller through the rotation of the hand crank. Stretching the power transmission line saves time and effort, and only one person can complete the entire installation process, which is convenient and fast. By setting the adjustment device, it can be applied to the stretching of power transmission lines of different thicknesses and has wide applicability.
