The present invention discloses a safety protection apparatus for limiting a working height of an operator on a wire pole. The safety protection apparatus is mounted on a conical wire pole and is below a cross arm, wherein the safety protection apparatus and the cross arm have a preset security distance. The safety protection apparatus includes a first protection board and a second protection board that are opposite. Opposite inner ends of the first protection board and the second protection board are provided with a semicircle hole separately. Openings of the two semicircle holes are opposite. The opposite inner ends of the first protection board and the second protection board are provided with a connecting structure that connects the first protection board and the second protection board, so that the two semicircle holes are combined so as to be sleeved on the wire pole. The safety protection apparatus can limit the working height of the operator on the wire pole, and ensures that the operator on the wire pole is far enough from an electric item on the cross arm when working on the wire pole, thereby guaranteeing operator safety and device security.
