The existing manual leveling trowels generally consist of a square tube and several rods. The rods are inserted into the ash, and the square tube is dragged to level the uneven ash layer. And this kind of structure of the leveling trowel generally can only level the thickness of the ash layer at the same height, and cannot adjust the height of the ash spreading rod on the leveling trowel according to the desired thickness of the mortar, which affects the applicable range of the leveling trowel. Therefore, the above problems need to be improved. Summary of the Utility Model
