The invention discloses a leveling device for an assembly type precast concrete wallboard. The leveling device comprises a first shell, wherein two fifth rods are symmetrically welded to each of the two sides of the outer side wall of the first shell, a second shell is welded to one ends of every two corresponding fifth rods, and a first sliding groove is formed in the inner side wall of each second shell. After the angles of two corners of the board surface of the concrete wallboard are measured, first plates are placed on the wall surface of a wall, second plates are pushed to trowel concrete on the wall surface, the angles of the two corners of the board surface of the concrete wallboard are adjusted to be right angles, and then the flatness of the concrete wallboard is improved; a second handle is pushed to drive a third plate to push the concrete on the wall surface for leveling, so that the flatness of the single side of the wall surface is higher, leveling of the wall surface isfiner, large-area protru
