摘要

The toothbrush has its head (1) mounted on a slide (6) which fits into the handle (3). This can be removed and replaced by a slide carrying another type of head, e.g. an interdental brush. A stop on the opposite end of the slide from the head fits into a recess (11) in the handle to lock it in place.
