[0002] At present, cross arms are often used on electric steel pipe towers to support and suspend cables. Most existing cross arms are integrated rigid structures. Usually, a predetermined installation position of the cross arm is set on the electric steel pipe tower. The position of the cross arm installed on the electric steel pipe tower cannot be adjusted. At the same time, the position of the cable fixed on the cross arm is also fixed. The height of the cable between two adjacent electric steel pipe towers is determined by the cable connection point on the cross arm. The existing integrated cross arm cannot fine-tune the fixed position of the cable in the horizontal and vertical planes according to the use requirements, so that the cross arm needs to be disassembled and re-fixed after being fixed, resulting in inflexible use of the cross arm and reduced working efficiency of the cross arm.
