Preferably, the cross section of the bump is cross-shaped, and the shape of the first through hole is matched with the shape of the bump.
Preferably, the diameter of the second through hole is larger than the width of the first through hole, and the width of the first through hole is larger than the diameter of the rod body.
Preferably, the limit bolt is screwed in the second through hole of the dental floss body, and the protruding block of the rotating rod penetrates through the third through hole of the limit bolt and is inserted in the first through hole of the dental floss body.
Preferably, a guiding part is arranged at the bottom of the dental strip body.
Preferably, a plurality of protrusions and grooves are staggered on the outer side of the screw head at the top of the limit bolt.
Preferably, the upper end of the rod body is provided with a groove, a rubber sleeve is adhered in the groove, and a plurality of anti-slip strips are uniformly arranged on the outer side of the rubber sleeve.
Preferably, the rod body and the bump are integrally formed.
The invention has the beneficial effects that: according to the invention, the cross-shaped protruding block is inserted into the second through hole, so that the rotating rod is screwed into or out of the dental strip body under the condition of not damaging the threads on the surface of the dental strip body, and the position of the protruding block is limited by the limiting bolt, so that the protruding block is prevented from falling out of the dental strip body.
The features and advantages of the present invention will be described in detail by way of example with reference to the accompanying drawings.
