The utility model relates to the technical field of constructional engineering, in particular to a device for controlling perpendicularity and flatness of a masonry wall, which comprises a base, and a vertical rod is arranged at the top of the base. The adjusting column can be driven to rotate by rotating the rotating ring, the base can be driven to ascend and descend by ascending and descending of the adjusting column, the base is adjusted to a proper height, and the laser lamps connected in series can be turned on by observing whether bubbles are in the middle or not and checking whether the base is inclined or not if the base is inclined, then adjusting the adjusting column, keeping the base horizontal and keeping the vertical rod in a vertical state. Laser is projected to a masonry wall needing to be constructed, then building blocks are built by being tightly attached to the edges of laser rays, when projection in different directions is needed, the handle is rotated to drive the vertical rod, the laser
