PURPOSE: A dental floss holder device is provided to easily insert a dental floss by making a cyclic dental floss with an endless track motion. CONSTITUTION: A dental floss holder device comprises a power generator(10) configured in order to generate a rotation by a spring form, and a driver(20) which is installed in one side of the power generator, and in which a cyclic dental floss exercises to a caterpillar through the power generator. The power generator comprises a handle(11) in which an inside is vacant in a barrel shape; a clockwork rotating with a fixed rotational frequency at a fixed time; a gear-box(12) reducing a rotating speed of the clockwork; a transmission rod(14) rotating according to a number of rotations in which the gear-box generates; and a switching device which controls the clockwork by switching on/off a rotation of the transmission rod. |
