As can be seen from fig. 1 and fig. 2, the overhead working cabling device of the power transmission line mainly comprises a main shell 1, a secondary shell 2, a rotating shell 3, a V-shaped handle 4, a friction plate 5, a double-torsion spring plate 6, a magnet 7, a protective belt 8, a rotating shaft 9 and the like. 3/5, the volume of the main shell 1 accounts for the total volume, the main shell is in a dumbbell shape, the upper half part of the main shell is a semi-arc-shaped wire groove with the inner diameter of 31mm, and the power transmission line is contacted with the upper surface of the inner side of the main shell 1 through the round wire groove in the working process; the lower half part is internally provided with two cuboid cavities of 40 multiplied by 17 multiplied by 12mm for installing a V-shaped handle 4 and a double-torsion spring sheet 6. The secondary shell 2 is fixed with the main shell 1 through a 2.5mm hexagon socket head cap screw and is used for auxiliary fixing of the V-shaped handle 4 and the double-torsion spring sheet 6. The rotary shell 3 is fixed on the secondary shell 2 through a rotating shaft 9, is internally provided with a circular arc-shaped wire groove with the diameter of 31mm, can freely rotate along the axial direction of the rotating shaft 9, and is matched with the main shell 1 so as to be separated from and engaged with a power transmission line under the condition of crossing a four-split spacing rod and the like. The V-shaped handle 4 is designed according to the lever principle, the included angle is 172 degrees, the V-shaped handle is divided into a front end part and a rear end part, the V-shaped handle is a key structure of the wiring device, the V-shaped handle and the double-torsion spring sheet 6 are fixed together in an internal cuboid cavity surrounded by the main shell 1 and the secondary shell 2, one side of the double-torsion spring sheet 6 is fixed at the lower edge of the internal cuboid cavity of the main shell 1, and the other side of the double-torsion spring sheet is in contact with the lower edge of the front end part of the V-shaped handle. The friction plate 5 is composed of a front end friction plate and a rear end friction plate, and is respectively fixed with two ends of the V-shaped handle 4 through a dovetail groove structure, as shown in fig. 3. The magnet 7 is a permanent magnet with a length, a width and a height of 4mm, and can be provided with 8 or 12 pieces, which are symmetrically fixed on the tangent plane of the main housing 1 and the rotary housing 3 (as shown in fig. 1), respectively, to form a locking mechanism of the routing device. The protective belt 8 is made of elastic material, and both ends of the protective belt are respectively fixed on the side edges of the main casing 1 (as shown in fig. 1) to prevent the protective belt from falling off.
