The invention relates to a building construction tool, in particular to a mould for a floor sewer line reserved hole. The mould comprises a circular truncated cone-shaped metal barrel body arranged above a floor formwork and a handle arranged at the upper part of the metal barrel body, wherein a metal ring-shaped reinforcing rib is arranged on the inner side wall of the metal barrel body; the area of the upper opening of the metal barrel body is greater than that of the bottom of the metal barrel body; a disc-shaped magnet is arranged at the bottom of the metal barrel body; the edge of the magnet is propped against the side wall at the bottom of the metal barrel body; a round metal plate attracted to the magnet is arranged below the floor formwork; a laser radiation lamp is hung in the center of the round metal plate. The mould adopting the technical scheme has high strength and can guarantee the perpendicularity and the quality of the reserved hole.
