It is about tools.

[0002]

2. Description of the Related Art It has been known that birds cause various harms by stopping on electric wires or the like.

As one of such harms, there has been a case where a bird stopped on an electric wire or the like attaches feces on the electric wire or the like. In addition, a bird that has stopped on an electric wire or the like comes into contact with a bird that has stopped on an opposite electric wire or the like, which may cause a short circuit accident.

Therefore, as a technique for preventing a bird from stopping on an electric wire or the like, for example, a bird harm prevention device described in Japanese Patent Publication No. 7-71372 is provided.

Hereinafter, this bird damage prevention device will be briefly described with reference to FIG.

This bird harm prevention device 100 is provided with a circular hole 110 in which a wire or the like is loosely fitted in a central portion of an elongated plate in a half-split shape.
A locking piece 120 is provided on the outer side of the half-edge so as to oppose it, and a plurality of supports 140 are formed so that the locking piece 120 can be opened and closed by a locking tool 130.
