Horizontal building punching device

The utility model relates to the technical field of buildings, in particular to a horizontal building punching device which is internally provided with a main box body, and the main box body is internally provided with a rotating cavity connected with the outside. When the friction plate is in contact with a flat wall surface, the hydraulic telescopic rod begins to extend to drive the rotary sliding block, the pushing sliding block, the pneumatic telescopic rod, the lifting rack and the punching drill bit to start to move back and forth, and meanwhile, the sliding motor begins to start to drive the sliding shaft to start to rotate. In addition, due to the fact that the lower end face of the friction plate is arranged to be in a sawtooth shape and is matched with the suction cup, double fixing of the wall is achieved, the friction force between the friction plate and the wall is increased, vibration during punching is prevented, and then it is guaranteed that punching is in a horizontal state all the time.
