PURPOSE: An H-beam type brush interchangeable toothbrush is provided to replace a brush of the toothbrush instead of buying a new toothbrush when the brush is bent by using for a long time. CONSTITUTION: An H-beam type brush interchangeable toothbrush is a coupling structure of a groove and a protrusion of H beam pattern, and it prevents the combining part from shaking in brushing teeth. A safety system using a contrived latch is used in order that the bond is easy but the separation is only possible with the special method. The toothbrush is a structure that a projection of H beam pattern comes out on the spot where the transplanted part finishes. The reason why the projection is designed in the form of the H beam is that the handle would not be rotated. |
