Adjustable cleaner

The utility model relates to an adjustable cleaner for cleaning the ground. A transmission pair is composed of a front driving wheel and an operating wheel. The operating wheel is coaxial with a cleaning brush; a four-bar mechanism is composed of a connecting rod, a sectional wheel and a machine frame. By using the rotation of the cleaning brush, the wastes on the ground are swept into a garbage bin. When the cleaning brush is grinded, and can not be effectively contacted with the ground, the service life of the cleaning brush is prolonged and the waste is reduced through adjusting a regulating device composed of the four-bar mechanism. Simultaneously, the adjustable cleaner for cleaning the ground is provided with a side brush and a scraper so that the utility model can effectively clean the ground rim that the cleaning brush can not touch.
