Special animal bite prevention device based on residual optical cable

The invention discloses a special animal bite prevention device based on a residual optical cable. The device comprises an aluminum alloy shell for accommodating the residual optical cable, the aluminum alloy shell is of a disc-shaped structure with an opening in one side, an aluminum alloy cover capable of being opened and closed is arranged at the opening of the aluminum alloy shell, and an extension groove for the residual optical cable to go in and out is formed in one side of the outer ring of the aluminum alloy shell. A rotating shaft mechanism for winding of the residual optical cable is fixedly arranged on the inner bottom face of the aluminum alloy shell. A binding belt is bound to an electric pole so that the aluminum alloy shell can be fixed to one side of the electric pole. The aluminum alloy shell is used for storing the residual optical cable, the aluminum alloy shell can protect the residual optical cable from being bitten by animals, an expelling mechanism in the aluminum alloy shell can expel
