The lower part of the first connecting component is installed together with the right part of the first support frame 4, and the lower part of the second connecting component is installed together with the left part of the second support frame 5; both the first bracket 6 and the second bracket 7 are post insulators.

[0021] According to requirements, a support cylinder in the shape of a cylindrical structure is fixedly installed on the outer side of the lower part of the rod body 1. The first rotating sleeve 2 and the second rotating sleeve 3 are sleeved between the inner side of the support cylinder and the outer side of the rod body 1 from outside to inside.

[0022] According to actual needs, the above-mentioned protection bracket for the transmission line can be further optimized and / or improved as follows:

[0023] Embodiment 2: As an optimization of the above embodiment, as shown in the attached Figure 1 , 2 , 3, the rain protection component includes an installation cylinder 8, a connection column 9 and a cover plate 10. An installation cylinder 8 with an upper opening and a lower closing is fixedly installed at the upper end of the rod body 1. A connection column 9 is fixedly installed in the center of the installation cylinder 8. A cover plate 10 with a distance between the upper end and the upper end of the installation cylinder 8 is fixedly installed at the upper end of the connection column 9.

[0030] During the use process, with such a setting, the second limiting block 19 can rotate circumferentially in the inner ring groove 12. In this way, the second support frame 5 can rotate along the rod body 1 according to the angle of the transmission line. The third connection base 18 is in a U-shape with an opening to the right. The upper part of the third connection base 18 is located between the cover plate 10 and the upper end of the installation cylinder 8, and the lower part of the third connection base 18 is located at the lower end of the inner ring platform 11.

Such a setting also facilitates the installation between the second support frame 5 and the rod body 1. The second limiting block 19 is located in the inner ring groove 12, which can avoid the phenomenon that the right end of the second support frame 5 bends downward after long-term use and can improve the connection strength between the second support frame 5 and the rod body 1.

[0032] During the use process, with such a setting, after the second limiting screw 22 is tightened, the third connection base 18 and the inner ring platform 11 can be fixedly installed together, which can fix the angle of the adjusted second support frame 5, avoid the shaking of the second support frame 5, and improve the stability of the second bracket 7 after installing the transmission line.

[0033] The above technical features constitute the embodiment of the present invention, which has strong adaptability and implementation effects. Non-essential technical features can be increased or decreased according to actual needs to meet the requirements of different situations.
