A plurality of adjusting holes II 15 are provided on one side of the support angle iron frame 3. A sliding groove 17 is provided on one side of the adjusting angle iron 2. The adjusting angle iron 2 is locked and fixed to the support angle iron frame 3 by bolts passing through the adjusting holes II 15 and the sliding groove 17. A plurality of locking holes 16 are provided at the top of the sliding groove 17, and the locking holes 16 are clamped with the bolts, so that the adjusting angle iron 2 is positioned. When the bolts for locking and fixing the adjusting angle iron 2 are loosened, the adjusting angle iron 2 can be pushed upward at this time, so that the bolts are disengaged from the locking holes 16 and enter the sliding groove 17, and then the adjusting angle iron 2 can be moved to change the position of the adjusting angle iron 2 on the support angle iron frame 3. After the adjusting angle iron 2 is moved to a suitable position, the adjusting angle iron 2 is moved downward so that the bolts enter the corresponding locking holes 16. At this time, the bolts are tightened to lock and fix between the adjusting angle iron 2 and the support angle iron frame 3, so that the size of the hoop cross arm can be changed, so that the hoop cross arm can cope with the situations where the installation positions are different, or are blocked, or need to be extended to avoid the position of the wire. There is no need to reprocess the hoop cross arm, which saves time and reduces costs. An installation component is provided on one side of the support angle iron frame 3 to install the support angle iron frame 3 on the electric pole.

At this time, the adjusting angle iron 2 can be pushed upward to disengage the bolt from the clamping hole 16 and enter the sliding groove 17. Then, the adjusting angle iron 2 can be moved to change the position of the adjusting angle iron 2 on the supporting angle iron bracket 3. After moving the adjusting angle iron 2 to a suitable position, the adjusting angle iron 2 is moved downward to make the bolt enter the corresponding clamping hole 16. At this time, the bolt is tightened to lock and fix between the adjusting angle iron 2 and the supporting angle iron bracket 3, thereby changing the size of the hoop cross arm, enabling the hoop cross arm to cope with situations where the installation positions are different, or there are obstructions, or the wire needs to be extended to avoid interference. There is no need to reprocess the hoop cross arm, saving time and reducing costs.
