Composite board perforating machine for building construction

The utility model belongs to the field of building construction, and particularly relates to a composite board perforating machine for building construction. The technical problem to be solved by theutility model is to provide the composite board perforating machine for building construction. A composite board perforating machine for building construction comprises a machine base, a first slidingrail, a first sliding block, an N-shaped sliding rod, a sliding sleeve, a mounting plate, a second sliding rail, a second sliding block, a rack, a first motor, a gear, an L-shaped fixing plate, a second motor and a drill bit. First sliding rails are fixedly connected to the two sides of the top of the machine base, and the two ends of the N-shaped sliding rod are slidably connected with the firstsliding rails through first sliding blocks. And the sliding sleeve is slidably connected with the N-shaped sliding rod. According to the utility model, the effects of high safety and high hole site perpendicularity are achieve
