Building outer wall surface punching equipment

The invention provides building outer wall surface drilling equipment, relates to the technical field of building construction, and aims to solve the problems that chippings and dust generated during drilling can be attached to the surface of an outer wall, cleaning is inconvenient, and high-altitude falling objects are likely to be generated. The rear end of the electric drill main body is fixedly butted with an L-shaped holding rod; a punching positioning frame is fixedly clamped at a drill bit of the electric drill main body; positioning guide rods are vertically and fixedly mounted at the upper end of the side wall of the front end of the punching positioning frame forwards in a bilateral symmetry manner; and a positioning seat plate is fixedly connected between the front ends of the left positioning guide rod and the right positioning guide rod. During punching, the punching equipment can be prevented from leaking chippings in the carrying and moving process, so that the punching equipment has the contin
