[0002] Iron accessories generally refer to iron parts on concrete poles and their connecting wires, such as various hoop irons, bolts, cross beams, cross braces, tie rods, wire rods, etc. Transmission lines mostly use cross-arm iron accessories for support and fixation, and the cross-arm iron accessories are installed on the poles. The cross-arm is an important part of the pole tower. Its function is to install insulators and fittings to support the conductors and lightning conductors and keep a certain safe distance as required.

[0003] In the existing patent with the application number CN202122431381.7, a high-stability cross-arm iron accessory is disclosed. By adjusting the angle of the diagonal strut with a second bolt, the diagonal strut is tightened against the hoop iron and the cross bar to improve the stability of the cross-arm. However, during the installation process of the cross-arm, it is often necessary to install the cross-arm at the center or one side of the pole according to the usage requirements, so different models of cross bars need to be produced, resulting in low applicability of the cross-arm and inability to meet the usage requirements.
