Dental floss holder

A dental floss holder is characterized by two interconnected but separable holder portions, U shape supporter (Portion 1) and a hollow grip (Portion 2) with the U shape supporter provided with a U supporter (1) with two folding legs, a connecting part (2), a hole (3) in a rear leg, a groove (4) that goes externally from an end of front leg until a fixed end of U supporter (I) to hold dental floss in position during cleaning operation, a longitudinal groove (6) with its depth decreasing from a threaded end (7) to a hole (5) of the connecting part (2), with a hollow grip (Portion 2) composed of a fixed side and a rotating side further characterized is that it can operate with a piece of floss from any required length as in the traditional way or from a continuous feeding from a floss supplier (12) connected to a rotary end (9), with a maximum tension limit being adjusted from the rotary end (9) of the hollow grip with a maximum tension control mechanism provided with a blade (8) with its height increasing from the fixed side, a groove (6) with its depth decreasing from the threaded end (7) to the hole (5), external (7) and internal threads (10) and the rotary end (9) to adjust the maximum floss tension with the tension created by how deep is the coupling between blade (8) and groove (6) which is controlled by the rotary end (9) that gives a penetration grade between the threads.
