As a further solution of the utility model: the U-shaped hanging plate is formed by tightly welding and bending a steel plate with a thickness of 150mm, a length of not less than 120mm, and a width of not less than 40mm and various angle irons.

As a further solution of the present invention: the end surface of the open ball hanging ring is provided with an annular through hole with an outer diameter of 50 mm, an inner diameter of 30 mm, and an opening of Φ18 mm.

As a further solution of the utility model: the open ball hanging ring is installed on the steel rod of the safety hook to form a circular hanging ring with an opening in a state of 360° free rotation.

Compared with the prior art, the beneficial effects of the utility model are as follows:

This anti-falling-off angle iron tightening wire lifting tool can be used to transfer materials, tools and tools at high altitude and install and erect various types of insulated wires and tension wires of 10kV distribution network power lines at high altitude. Convenience, especially in the process of replacing tension insulators and wires during the maintenance of distribution network, the tools used are simplified and neat, which saves the working time of electric power maintenance workers on the ground and towers, and can improve the replacement of tension insulators and wires on power lines. The speed and work efficiency of tightening the line; and the tool can be used as a good helper for lifting personal tools and transferring materials when the angle iron is vertical, inclined, or horizontal. Heavy-duty safety performance, in line with the requirements of maintenance operations, easy to disassemble, replace, transport, and operate.
