In this example, a plurality of first mounting holes 2-1 are arranged, and the sleeve 5 is connected to the cross bar 2 by bolts. The position of the sleeve 5 can be adjusted as needed to change the distance between the overhead lines.

[0024] like Figure 3-6As shown, the fixing member 6 includes a base 6-1, a rear clamping frame 6-2 is installed on the base 6-1, the bottom surface of the rear clamping frame 6-2 is connected to an adjustment component, a front clamping frame 6-3 is installed above the rear clamping frame 6-2, the rear clamping frame 6-2 and the front clamping frame 6-3 form an overhead line placement cavity, and two rear support blocks 6-6 are also installed on the top surface of the base 6-1, and the two rear support blocks 6-6 are located inside the rear clamping frame 6-2, and the front clamping frame 6 -3 is provided with a front support block 6-7 on the top inner wall, and a second adjusting screw 6-8 is provided on the top surface of the front support block 6-7, and the second adjusting screw 6-8 is threadedly connected to the front clamping frame 6-3 and extends to the top of the front clamping frame 6-3; by rotating the second adjusting screw 6-8, the second adjusting screw 6-8 drives the front support block 6-7 to rise or fall, thereby changing the distance between the rear support block 6-6 and the front support block 6-7, so as to match overhead lines of different diameters.

[0025] The adjustment assembly includes a first adjustment screw 6-4, the first adjustment screw 6-4 is connected to the bottom surface of the rear clamping frame 6-2, the outer side of the first adjustment screw 6-4 is threadedly connected to an adjustment nut 6-5, a limiting groove 6-1-1 is provided on the base 6-1, and the adjustment nut 6-5 is arranged in the limiting groove 6-1-1, and the limiting groove 6-1-1 is provided to prevent the adjustment nut 6-5 from moving up and down; Figure 5 As shown, at this time, the rear clamping frame 6-2 is located at the front end, and the adjusting nut 6-5 is turned.
