Portable wall perpendicularity rapid detection tool

The invention discloses a portable wall perpendicularity rapid detection tool, and relates to the technical field of construction detection. According to the technical key points, the device comprises an upper end vertical rod and a lower end vertical rod, the upper end vertical rod is inserted into the lower end vertical rod, the upper end vertical rod and the lower end vertical rod are in threaded connection, the top end of the upper end vertical rod is fixedly connected with an upper transverse rod, the upper end vertical rod is perpendicular to the upper transverse rod, a wire groove is formed in the upper transverse rod, and a wire rope is connected to the wire groove in a hanging mode. And one end of the rope is connected with a plumb bob. The device has the advantages that the device is high in wall perpendicularity detection speed and high in efficiency, re-checking is performed through 20 control lines, control is performed through the distance between a rope and the wall, two measures are taken into
