The inner layer splint 11 and the outer layer splint 12 both include a first clamping plate and a second clamping plate, and the second clamping plate is fixedly arranged at one end of the first clamping plate, and is perpendicular to The first clamping plate extends to one side. The first clamping plate and the second clamping plate together form an L-shaped structure.

A first bolt assembly is arranged between the first clamping plate of the inner layer splint 11 and the first clamping plate of the outer layer splint 12, and a wing plate of the pole angle 2 passes through the first bolt assembly Clamped between the first clamping plate of the inner layer splint 11 and the first clamping plate of the outer layer splint 12 .

A second bolt assembly is arranged between the second clamping plate of the inner layer splint 11 and the second clamping plate of the outer layer splint 12, and the other wing plate of the pole angle 2 is passed through the second bolt assembly. The assembly is clamped between the second clamping plate of the inner clamping plate 11 and the second clamping plate of the outer clamping plate 12 .

Both the first bolt assembly and the second bolt assembly include a locking bolt 131 and a locking nut 132 disposed on the locking bolt 131 . A spring washer (not shown in the figure) is sleeved on the locking bolt 131 between the head of the locking bolt 131 and the outer splint 12 . The first clamping plate and the second clamping plate of the inner layer clamping plate 11 are provided with a first mounting hole 111 for receiving the end of the locking bolt 131, and the first clamping plate of the outer layer clamping plate 12 The plate and the second clamping plate are provided with a second mounting hole 121 for receiving the end of the locking bolt 131 .

Furthermore, because the angle steel types used by different poles are different, some are large in size and some are small in size. However, there are certain requirements for the installation positions of the first bolt assembly and the second bolt assembly, that is, the distance N between the first bolt assembly and the second bolt assembly and the pole angle steel 2 cannot be too large. If the distance N is too large, the outer splint 12 and the inner splint 11 are easily deformed under the locking force of the first bolt assembly and the second bolt assembly, resulting in the inability to clamp the pole angle steel 2, resulting in unreliable installation.

In view of this situation, if the first installation hole 111 and the second installation hole 121 adopt round holes, when the size of the pole angle steel 2 is large, the installation of the first bolt assembly and the second bolt assembly The position can meet the requirements or can generally meet the requirements, and when the stay wire anchor provided by the embodiment of the present application is installed on a pole with a smaller size of the pole angle steel 2, the distance between the first bolt assembly and the second bolt assembly The distance N of the pole-holding angle steel 2 will be too large, which cannot meet the installation requirements.

In this way, the installation positions of the first bolt assembly and the second bolt assembly can be adjusted according to the size of the pole-holding angle steel 2 , so that the distance from the first bolt assembly and the second bolt assembly to the pole-holding angle steel 2 meets requirements.

For the convenience of description, the symmetrical plane of the first clamping plate of the outer layer clamping plate 12 and the second clamping plate of the outer layer clamping plate 12 is defined as the first symmetrical plane.

Further, in order to avoid movement and change of the positions of the first bolt assembly and the second bolt assembly during the working process.
