Floor plate elevation controller with adjustable precision

The utility model discloses a floorboard elevation controller with adjustable precision, which comprises a base and an elevation adjuster, the upper surface of the base is provided with a threaded hole, the excircle of the elevation adjuster is provided with an external thread, and the external thread is in threaded connection with the threaded hole to install the elevation adjuster on the base; the elevation adjustor ascends or descends in the vertical direction by twisting the elevation adjustor, so that the overall height of the floor plate elevation controller is increased or decreased. When the formwork is sunk and deformed due to the dead weight and vibration load of poured concrete, the overall height of the floor plate elevation controller can be increased or decreased by twisting the elevation adjustor and enabling the elevation adjustor to ascend or descend in the vertical direction in the later concrete surface finishing process, and therefore the flatness and elevation of a floor are controlled; t
