Light portable adjustable laser detection tool for detecting verticality

The utility model relates to a light portable adjustable laser detection tool for detecting verticality. At present, a plumb bob and a coiled material detection tool need to be carried at the same time when perpendicularity detection is carried out on a wall surface, multiple persons need to cooperate for detection, detection is tedious, and meanwhile detection results are prone to errors. The device comprises a telescopic main arm (2) and two telescopic support arms (3), the telescopic support arms are connected with the end part of the telescopic main arm through a hinging part (9), the end part of each telescopic support arm is connected with a flitch (5) through a universal joint (4), a graduated scale (7) is fixed at the hinging end of each telescopic support arm and the telescopic main arm, and the graduated scale is connected with the flitch (5) through a universal joint (4). And a grip (10) is welded on the telescopic main arm and is connected with a plumb bob bidirectional laser transmitter (8) throu
