To improve the construction efficiency of highway bridges, a leveling device is usually used to level the concrete surface.

[0003] In the process of using the existing leveling device, the spreading radius is fixed and cannot be adjusted adaptively according to the actual area size of the leveling position. As a result, the leveling device cannot level narrow areas and reduces the leveling efficiency of the leveling device in open areas. Operators need to replace scrapers of different sizes according to the situation, thus reducing the working efficiency of the leveling device.

[0004] Regarding the above related technologies, the inventor believes that the fixed spreading radius of the leveling device reduces the flexible adaptability of the leveling device, thereby reducing the working efficiency of the leveling device. Content of the Utility Model
