| description | The punching device comprises two concave plates, threaded holes are formed in the upper surfaces of the concave plates, the inner walls of the threaded holes are in threaded connection with lead screws, the top ends of the lead screws are fixedly connected with rotating blocks, the bottom ends of the lead screws are rotationally connected with limiting blocks through bearings, and the upper surfaces of the concave plates are fixedly connected with fixing cylinders. A sliding block sleeves the inner wall of the fixed cylinder, a moving rod is fixedly connected to the upper surface of the sliding block, a spring is fixedly connected to the lower surface of the sliding block, a mounting plate is fixedly connected to the top end of the moving rod, and a motor is arranged on the upper surface of the mounting plate. According to the perforating device for constructional engineering, drilling of a plate is facilitated by arranging the motor and the drill bit, vertical movement of the motor is facilitated by arrangi |
