Thermal insulation outer wall punching device for constructional engineering

The invention belongs to the technical field of building construction, and particularly provides a thermal insulation outer wall punching device for constructional engineering, which comprises a base, the upper part of the base is symmetrically provided with total height adjusting frames, the total height adjusting frames are of electric telescopic structures, and the upper ends of the total height adjusting frames are rotatably connected with space adjusting bracket assemblies; a safety adjusting type drilling assembly is movably arranged on the space adjusting support assembly. The space adjusting support assembly protects and supports an electric drill bit through a ball adjusting supporting mechanism and a drill bit protection mechanism, the perpendicularity of the electric drill bit and the wall surface is kept all the time while the surface state of the wall surface is guaranteed during punching operation, and the punching quality is guaranteed. The arranged space adjusting supporting assembly forms a c
