Mechanical and electrical installation positioning and punching device for building construction

The utility model relates to the technical field of building construction, and discloses an electromechanical installation positioning and punching device for building construction. A plate is placed in the fixing block, the telescopic pressing rod is used for driving the fixing plate to vertically move to fix the plate needing to be punched, when the plate is placed in and pulled out of the fixing block, the pin rollers roll, more labor is saved, plates of different specifications and sizes can be fixedly clamped, and flexibility is improved; the motor is started and drives the threaded rod to rotate, so that the movable box horizontally moves on the surface of the threaded rod, meanwhile, the limiting plate slides on the surface of the sliding rod, the air cylinder is started to vertically move to the position needing to be punched, the infrared marker is used for checking, the puncher is used for punching, and the electric fan is started. And dust is sucked into the cylinder, reaches the filter cartridge a
