RTV coating spraying device

The invention relates to an RTV coating spraying device which comprises a straight rod assembly. The deformation assembly is arranged at the front end of the straight rod assembly, the deformation assembly can be bent into a circular ring shape or unfolded into a straight strip shape, and a nozzle is formed in the inner ring of the circular-ring-shaped deformation assembly. The deformation assembly is formed by rotationally connecting a plurality of toggle joints; a hose first control rope and a hose second control rope are arranged in the toggle joint in a penetrating manner, and the first control rope and the second control rope are located on the two sides of the toggle joint respectively; and a first side nozzle communicated with the hose is formed in the side wall of the toggle on one side of the second control rope. Each toggle joint is provided with a first synchronous plate, a second synchronous plate and a rotatable center rotating shaft which can slide in the length direction of the toggle joint, th
