Spraying device used for aircraft empennage

The invention discloses a spraying device used for an aircraft empennage. The spraying device comprises a base, supporting legs are evenly arranged on the lower surface of the base, and a spraying platform is arranged at the center of the upper surface of the base. When the curved surface of the aircraft empennage is sprayed, a telescopic motor shell is fixed to the interior of a sliding groove ofthe side wall of the spraying platform so that the spraying device can conduct circular movement along the sliding groove and is suitable for spraying of the curved surface; during linear spraying, the spraying device can realize 360 degrees of spraying and conduct spraying on the aircraft empennage in all directions, so that the spraying device is suitable for the complex surface of the aircraftempennage; through a parallelogram mechanism formed by fixing rods and rotating connection rods, small-range moving of a spraying gun in the upper, down, left and right directions can be realized, sothat the spraying device i
