Multifunctional leveling instrument suitable for assembly type enclosing wall installation detection

The utility model discloses a multi-functional level ruler suitable for assembly type enclosure installation detection, which comprises a middle straight rod, side straight rods and end straight rods, the two side straight rods are symmetrically hinged to the two ends of the middle straight rod, the end straight rods are symmetrically hinged to the ends of the two side straight rods, a gradienter is embedded in the middle of the middle straight rod, and the gradienter is embedded in the middle of the middle straight rod. A positioning component is detachably connected between every two adjacent rod pieces. The straight rods are hinged, and the positioning plates are detachably connected between the adjacent straight rods to fix the unfolded angle, so that the leveling instrument can be unfolded to form a concave structure to bypass the blocking of the wind-resistant column to measure the perpendicularity and flatness of the ground beams/wallboards on the two sides of the wind-resistant column, and a worker ca
