Embodiments of the present invention will be described below with reference to the drawings.

As shown in FIG. 1, the fixing device of the present invention for fixing a power pole mounting bird harm prevention device comprises a combination of a fixing device main body 2 and falling-off prevention pins 4. The fixture body 2 has a pair of legs 8 formed downward and parallel at both ends of a flat top 5 and a mounting plate 3 parallel to the top 5 at a predetermined interval from the top 5 at both ends. It is provided between the legs. The top 5 has a hole 6 for attaching a utility pole mounting tool, and a lower end of each leg 8 is provided concentrically with a drop-out prevention hole 7 penetrating inward and outward.

At one end of the pin portion of the drop prevention pin 4,
Engagement portion 10 of size that is forcibly fitted into hole 7 for preventing falling off
Is provided, and a stopper 9 for retaining is provided at the other end.

The diameter of the fall-prevention pin 4 is smaller than the diameter of the fall-prevention hole 7, so that the fall-prevention pin 4 can be easily passed through the hole 7. Also, the stopper 9 for retaining is formed to be larger than the diameter of the hole 7 for preventing falling off, and when the pin 4 for preventing falling is passed through the hole 7 for preventing falling off, the pin 4 for preventing falling off comes out of the hole 7. Prevent passing through. The stopper 9 for retaining is formed in a cylindrical or columnar shape having a diameter larger than the hole 7 or a spatula-shaped one as shown in FIG. Any shape may be used as long as it is larger than the diameter of the drop-out preventing hole 7. Stopper 9 for retaining
Is also used as a grip for the drop-out prevention pin 4 because of the shape described above.

The locking portion 10 is a projection provided at the other end of the falling-off prevention pin 4 as shown in FIG. 1, and this projection has a total height and a diameter of the pin 4 that prevent the falling-off. It is formed to be slightly larger than the diameter of the hole 7. For this reason, when passing the fall prevention pin 4 through the fall prevention hole 7, it is necessary to forcibly push it. At this time, the drop-out preventing pin 4 is forcibly fitted into the drop-out preventing hole 7 and cannot be easily pulled out.
