The main connecting body 1 is L-shaped and is used for connecting the main structural part of the power iron tower. The two ends of the main connecting body 1 are both provided with the vice connecting body 2, and the two vice connecting bodies 2 are both used for expanding the connecting length of the main connecting body 1, thereby increasing the flexibility and application range of the connecting structure. The material of the main connecting body 1 and the vice connecting body 2 is Q345B steel, and the thickness is 8-12 mm.

[0031] A set of expansion assemblies are arranged between the main connecting body 1 and each vice connecting body 2 and are used for driving the vice connecting body 2 to slide relative to the main connecting body 1, thereby expanding or shortening the total length of the connecting structure. Each set of expansion assemblies comprises a limiting groove 3 arranged in the main connecting body 1, the limiting groove 3 has a convex cross section, the height of the convex cross section of the limiting groove 3 is 5-10 mm, and the vice connecting body 2 slides in the limiting groove 3, thereby ensuring that the vice connecting body 2 can stably slide on the main connecting body 1 without falling off.

The limiting assembly comprises a sliding groove 6 arranged in the vice connecting body 2 and a limiting bolt 8 sliding in the sliding groove 6. The side end of the main connecting body 1 is fixed with a fixed nut 7, and the limiting bolt 8 is threadedly connected in the fixed nut 7. When the vice connecting body 2 is slid to the appropriate position, the limiting bolt 8 is tightly matched with the fixed nut 7 by being tightened, thereby fixing the vice connecting body 2 on the main connecting body 1.

[0033] In order to more accurately position the position of the vice connecting body 2, each set of positioning assemblies comprises two recesses 10 arranged in the vice connecting body 2, and the two recesses 10 are both slidingly provided with a limiting block 9. A positioning spring 11 is fixed between the two limiting blocks 9, and the positioning spring 11 provides elastic force for the limiting block 9, so that the limiting block 9 can be tightly clamped with a positioning groove 12 in the main connecting body 1. Two positioning grooves 12 are arranged in the main connecting body 1, and when the vice connecting body 2 is slid to the appropriate position, the limiting block 9 is clamped into the positioning groove 12 under the action of the positioning spring 11, thereby fixing the position of the vice connecting body 2.
