A fitting bulge and a joined clip lid is each installed on the top surface of the curved end, and the joined clip lid has a fitting fillster installed matching the fitting bulge. The fitting fillister of the joined clip lid can fit the fitting bulge and fix the brush shaft inserted in the brush shaft installation opening by pushing back the rear of the brush shaft and clip it tight to fix, and in turn enables the installation and replacement of the brush shaft. The brush handle in formed of two parts connected by an axis so that it can revolve, the connecting surface has several indents and bulges arranged in a circle to fix the location of the revolving. The characteristic of this inter-dental brush structure is to adjust to the angle needed for brushing the rear teeth crevices, and increase the convenience of usage.
