Vertical leveling device for tiling

The vertical leveling device for tiling comprises a supporting box, sliding mechanisms are symmetrically arranged on the two sides of the supporting box, supporting legs are arranged at the output ends of the sliding mechanisms, adjusting mechanisms are arranged on the rear surfaces of the supporting legs, the adjusting mechanisms are connected with one side of the supporting box through a connecting mechanism, and the other side of the supporting box is connected with a leveling mechanism. A rotating mechanism is arranged in the supporting box, a gradienter body is arranged at the top of the rotating mechanism, a sliding adjusting mode is adopted, a supporting leg fixedly connected with one side is driven to adjust the height, a spring is adopted as a driving part after adjustment, and a moving plate and a connecting block on the moving plate are driven to be clamped into a connecting groove; according to the leveling device, the supporting legs are adjusted, the adjusted supporting legs are limited, the sup
