ABSTRACT:
A safe roll-scraping ear pick includes a stick, a seat as well as a screw spring set including an exterior screw spring and an interior screw spring is disclosed. The stick is provided on one end thereof with the seat; the screw spring set is slipped over the seat. Thereby, rings on the exterior screw spring of the screw spring set all have chances to contact a wall of an ear. By rolling to and fro of the stick, the multiple rings can scrape and remove ear wax. This can increase efficiency of cleaning with the safety of non-damage to the tissue of ears.
