[0002] As we all know, overhead lines mainly refer to overhead open lines, which are erected above the ground. Insulators are used to fix the transmission wires on pole towers erected on the ground to transmit electrical energy. They are easy to install and maintain, with low costs, but they are easily affected by weather and environment and cause failures. At the same time, the entire transmission corridor occupies a large area of ​​land and is prone to cause electromagnetic interference to the surrounding environment.

[0003] The pole top bracket used in the overhead lines in the past usually fixes the bracket on the tower pole. For example, the prior art CN220107534U discloses an overhead line pole top bracket, including a first clamp, a second clamp, a support plate, a top frame, a connecting plate and a pole, wherein the first clamp is arranged on the top of the pole; the two sides of the clamp are fastened by screws so that the bracket is tightly fixed on the pole through two groups of clamps; the four support plates cooperate with the connecting plate to greatly improve the stability of the top frame; the reinforcing ribs on the support plate further improve the strength of the entire bracket; the diameters of the first clamp and the second clamp are both in line with the pole diameters at their locations, so that they can be better fastened to the pole.

[0004] However, in the use of existing pole-top brackets for the erection of multiple lines, since the mounting structures between the pole-top brackets are all installed and fixed in one position, in the subsequent line erection process, it is impossible to adjust the spacing between the pole-top brackets according to the actual line erection needs, resulting in great limitations in the use of the entire device bracket, and it is difficult to meet the use requirements of different line spacings.
