7A to 7D are views for explaining a state of use of the overhead distribution line fixing device, which is convenient for maintenance work according to the present invention, and will be described with reference to this.

When trying to cut off the power to check the overhead power distribution line (L) and the jumper wire (J) in the installed state as shown in FIG. Walk, then pull downwards.

As described above, when the lock 340 is pulled downward, the lock 340 is separated from the locking hole 332b, and at the same time, the movable table 330 fixed by the lock 340 is compressed by the torsion spring. Rotated around the shaft rod 325 by the restoring force of 360, the lock 340 naturally moves along the arc hole 332a, as shown in FIG. 7b.

And, due to the rotation of the movable table 330, the contact connection between the convex ground 380 and the concave ground 370 is naturally released, and accordingly, the electrical connection between the jumper wires (J) is also released, which is shown in FIGS. 7C and 7C and FIG. It is shown as 7d.

If both the first and second lighting units 500 and 500' are lit despite the contact connection between the convex ground 380 and the concave ground 370 being released, it is considered that the power cutoff (release) has not been properly performed. Since the operator can quickly reorganize, there is an advantage in that the risk of electric shock to the operator can be prevented in advance.

On the other hand, after the inspection work is completed, when the hook (not shown) of the rod (not shown) is hooked to the movable table 330 and pulled in a counterclockwise direction, the lock 340 is moved to the lock metal coupling part 332. As it is pulled in, the fixed base 320 and the movable base 330 are fixed to each other, and in this process, the concave ground 370 and the convex ground 380 are electrically interconnected while facing each other.

According to the present embodiment, various tools required for work can be temporarily placed on the workbench 400 so that the work can proceed more conveniently, and the jumper wire J can be connected and disconnected easily and conveniently, so the work is convenient. has the advantage of greatly improving
