[0022] See also Figures 1 to 5 , an overhead power line protection hardware, comprising a support portion 20, an adjustment portion 30 and a plurality of cable fixing portions 40 arranged between a plurality of cables 10. When the overhead power line protection hardware is in use, the adjustment portion 30 can be operated so that the plurality of cable fixing portions 40 adjust the spacing between the plurality of cable fixing portions 40 and the support portion 20, so that the plurality of cable fixing portions 40 clamp the cables 10 to limit the position.

[0023] In this embodiment, the support part 20 includes a first end cap 21, an insertion shaft 22, and a second end cap 23. The first end cap 21 and the second end cap 23 are respectively passed through the centers of the two ends of the insertion shaft 22, and the first end cap 21 and the second end cap 23 are fixedly connected to the insertion shaft 22. When installing the overhead power line protection hardware, the support part 20 can be set as a whole between multiple cables 10.

[0024] In this embodiment, the adjusting part 30 includes an adjusting disk 31, a driven gear 32, a driving gear 33, an adjusting shaft 34 and two limit nuts 35. The driven gear 32 and the adjusting disk 31 are fixed to each other on the opposite sides and are coaxially arranged therebetween. In addition, the driven gear 32 and the adjusting disk 31 are both sleeved on the outer side of the plug-in shaft 22 and are rotatably connected thereto. The driving gear 33 and the driven gear 32 are meshed with each other, so that when the driving gear 33 rotates, the driven gear 32 and the adjusting disk 31 can be driven to rotate simultaneously. One end of the adjusting shaft 34 passes through the first end cover 21 and extends between the adjusting disk 31 and the first end cover 21, and the driving gear 33 fixedly connected thereto is sleeved on one end of the adjusting shaft 34 located between the adjusting disk 31 and the first end cover 21, so that when the adjusting shaft 34 is rotated, the driving gear 33 can be driven to rotate simultaneously therewith. An external thread matching the limit nut 35 is provided on the outer wall of the adjusting shaft 34, and the two limit nuts 35 are separated by the first end cover 21, so that the rotation of the adjusting shaft 34 can be prevented after the two limit nuts 35 are tightened and the first end cover 21 is clamped; after the two limit nuts 35 are loosened, the adjusting shaft 34 can be operated to rotate.

[0025] In this embodiment, the cable fixing part 40 includes a wire pressing plate 41, a sliding plate 42 and a positioning protrusion 43.

The adjusting disk 31 is formed with a plurality of grooves 311 on one side facing the positioning protrusion 43, the grooves 311 are set to be in an arc shape, and the width of the grooves 311 is adapted to the diameter of the positioning protrusion 43. The positioning protrusion 43 can extend into the groove 311, and by rotating the adjusting disk 31, the inner wall of the groove 311 can apply force to push the positioning protrusion 43, thereby driving the cable fixing part 40 to move. The number of grooves 311 is equal to the number of cable fixing parts 40, and the plurality of grooves 311 are evenly distributed along the radial direction of the adjustment disk 31, so that the plurality of cable fixing parts 40 can be adjusted by the adjustment disk 31 and move simultaneously. The second end cover 23 is formed with a plurality of guide rail parts 231 on one side facing the sliding plate 42, and a guide groove matching the sliding plate 42 is formed in the middle of the guide rail part 231. The plurality of guide rail parts 231 are all formed at the outer edge of the second end cover 23, and the plurality of guide rail parts 231 are evenly distributed along the radial direction of the second end cover 23.
