L'outil de nettoyage comprend un boîtier et une pince. Le boîtier comprend un conduit disposé à l'intérieur du boîtier ; la pince est au moins partiellement disposée dans le conduit et apte à effectuer un mouvement de va-et-vient le long de la direction de la profondeur du conduit. Une extrémité de la pince est pourvue d'une griffe de serrage. La griffe de serrage peut s'étendre hors du conduit sous l'effet du mouvement de la pince le long du conduit, ou se rétracter au moins partiellement ; la griffe de serrage s'ouvrant lorsqu'elle s'étend hors du conduit et se refermant lorsqu'elle se rétracte dans le conduit.
