Levelness and perpendicularity measuring and detecting device

The invention belongs to the technical field of measurement and detection, and discloses a levelness and perpendicularity measurement and detection device, the levelness and perpendicularity measurement and detection device comprises a shell, a reader and a leveling piece, and the side wall of the shell is provided with a horizontal laser generator and a vertical laser generator; the reader is inserted into the shell, the reader is detachably connected with the shell, and scale marks are arranged on the reader; the multiple leveling pieces are arranged at the bottom of the shell, and the leveling pieces can adjust the levelness of the shell. According to the levelness and perpendicularity measuring and detecting device provided by the invention, the readers are horizontally placed on the basic steel plate embedded parts in sequence, and the levelness between the basic steel plate embedded parts is evaluated through the horizontal numerical values obtained by projecting the laser emitted by the horizontal lase
