The invention relates to a folding pole and tower anti-bird device. The folding pole and tower anti-bird device comprises a bottom plate, a rear vertical plate and a front inclined plate, wherein the rear vertical plate and the front inclined plate are rotationally connected to the bottom plate and connected through a connecting mechanism, a frame is formed on the bottom plate by the rear vertical plate and the front inclined plate in a defined mode through connection of the connecting mechanism, the two ends of the frame are sealed through a foldable connecting plate, one end of the connecting plate is rotationally connected with the front inclined plate, the other end of the connecting plate is rotationally connected with the bottom plate, and the connecting mechanism is loosened so that the front inclined plate and the rear vertical plate can form a plane on the bottom plate, wherein a maintainer can carry out maintenance on the plane conveniently. The folding pole and tower anti-bird device has the advantages that the frame is assembled on the bottom plate by the rear vertical plate and the front inclined plate through the connecting mechanism, the rear vertical plate and the front inclined plate are rotationally connected to the bottom plate, the frame structure can be adjusted according to different installing occasions, the size of the whole frame is effectively adjusted, and the problems that an existing anti-bird plate is large in size and fixed in shape are solved.
