Outdoor distribution box with high-stability supporting base

The utility model discloses an outdoor distribution box with a high-stability supporting base, which comprises a base body, the upper end of the base body is provided with a distribution box body, the lower end of the base is provided with a plurality of symmetrically arranged supporting columns, and the lower ends of the two supporting columns on the same side are jointly connected with a mounting plate. A plurality of symmetrically-arranged mounting holes are formed in the two mounting plates, grooves are formed in the upper ends of the two mounting plates, supporting mechanisms used for reinforcing supporting are arranged between the grooves in the same side and the two supporting columns, and driving mechanisms used for driving the supporting mechanisms are arranged in the multiple supporting columns. Through downward movement of the movable plate, the two sliding blocks move dispersedly on the outer wall of the sliding rod, so that the supporting columns are supported by the two connecting rods, and the
