Improved structure of dental floss rod

An improved structure of a dental floss rod gives priority to a dental floss rod body, wherein the front section of the dental floss rod body is a dental floss head, the rear section thereof is a dental cusp tail, a cutting groove is arranged on a lateral plane surface of the middle section of the dental floss rod body, taking the cutting groove as the center, an embedded clamping seat which is concavely provided with an embedded clamping groove in the center is thickly arranged on the upper half portion of the other lateral plane surface, the lower half portion is convexly provided with a relative embedded clamping strip, and the shapes of the embedded clamping groove and the embedded clamping strip are mutually complemented. After the dental floss rod is used, by using the cutting grooveas the axial center, the dental floss rod can be folded towards two sides to force the embedded clamping seat to be relative to the embedded clamping strip, thereby the embedded clamping strip can enter into the embedded cla
