Novel support system haunch leveling block

The utility model belongs to the technical field of leveling blocks, and particularly discloses a novel support system haunch leveling block which is characterized in that a limiting rod is arranged at one end of the leveling block, an extension rod is arranged in the limiting rod, a conical rod is arranged in the extension rod, a first connecting piece is arranged on the outer side of the limiting rod, and a second connecting piece is arranged on the outer side of the first connecting piece. The limiting rod, the extension rod and the conical rod are embedded into the ground, so that the leveling block is limited and cannot move, when the limiting device is not used for limiting on the construction section of the cement ground, the protruding block slides upwards, the protruding block, the limiting rod, the extension rod and the conical rod are separated from the leveling block, and the construction safety of the frame body is guaranteed through the leveling block; the overall construction progress and the c
