The angle adjustment assembly 3 is connected to the moving part 2, and the scraper 4 is connected with the angle adjustment assembly 3. The angle adjustment assembly 3 is used to adjust and fix the angle between the board surface of the scraper 4 and the plane where the design elevation is located, so that the scraper When the plate 4 moves along the length direction of the guide rail 1 driven by the moving member 2, the angle between the side of the plate surface of the scraper 4 facing the moving direction of the scraper 4 and the plane where the design elevation is located is fixed and is an acute angle.

In order to easily show the structure of the angle adjustment assembly 3, the board surface of the scraper 4 shown in Figures 1 and 2 is attached to the top surface of the concrete structure to be leveled. At this time, the board surface of the scraper 4 is the same as the design elevation. The angle between the planes is 0 degrees.

When leveling the top surface of the concrete structure to be leveled before the concrete is initially set, the guide rail 1 in this embodiment may first be fixed on the top of the concrete structure to be leveled. Since the formwork used to enclose the concrete structure is generally higher than the top surface of the concrete structure to be leveled, when the guide rail 1 is fixed, the guide rail 1 can be directly fixed on the above formwork.
