The utility model discloses a pole anti-inclination device for a transmission and distribution line. The pole anti-inclination device comprises a pole bottom disc, the upper portion of the pole base disc is a cone, the lower portion of the pole base disc is a cylinder, and the cone and the cylinder are integrated. The upper portion of the cone is provided with a central locating hole and four peripheral locating holes, the four peripheral locating holes are evenly distributed around the central locating hole, and reinforcing ribs penetrating through the cones are arranged at the central positions of the central locating hole and the four peripheral locating holes. The middle and lower portion of the cylinder is provided with a central concave spherical arc face and four peripheral concave spherical arc faces, and the four peripheral concave spherical arc faces are evenly distributed around the central concave spherical arc face. When the pole anti-inclination device is used, the pole anti-inclination device is first buried in soil, then a cement pole is directly inserted into the locating holes, and secondary cement pouring is conducted at the connecting position. Due to the fact that the bottom of the pole anti-inclination device for the transmission and distribution line is provided with the multiple concave spherical arc faces, after the pole anti-inclination device is buried in the soil, the area of the pole in contact with the soil is increased, sinking and inclination of the pole can be effectively solved, and performance of the pole is completer.
