Description of the invention (The present invention relates to a dental floss holder, in particular, a dental floss > a dental floss holder which is approximately orthogonal and can be replaced in a timely manner. Press' With With the popularization of education and the improvement of quality of life, people not only increase the environmental hygiene requirements, but also pay more and more attention to their own sanitation, such as the increase in the demand for toilet tissue paper, clean dental floss or dental floss rods. The increase in sales is the best example. Floss sticks are used to clean the best hygienic products at present. It is more convenient to use floss. It is also more common and can effectively prevent the critical surface between teeth. The “dental tooth” is referred to the first figure, which is a schematic diagram of a conventional dental floss rod. In order to facilitate the manufacture of the conventional dental floss rod 1, generally, plastic is used as a material, and a gate-shaped connection is formed at the front end of the dental floss rod 1. The dental floss 12 is connected to the connecting portion 11 in a continuous manner. Therefore, the dental floss 12 and the dental floss rod 1 are in an approximately parallel state. Although the dental floss 12 in this state can easily remove the front teeth of the oral cavity Crevice of tartar 'but when To remove tartar from the teeth between the teeth on both sides of the mouth, it is very likely that the floss rod 1 must be placed in the mouth, so that the floss i 2 is parallel to the gap, so that the floss 1 2 can easily pass through the gap. The cleaning action is inconvenient for use. Furthermore, since the two ends of the dental floss 12 are only covered by the material of the dental floss rod i, because the connection strength between the two is low, it is often used during use. It breaks from the connection between the two. At this time, the dental floss rod 1 is unusable, and the entire dental floss rod 14 must be discarded, which is a waste of resources and has no environmental protection concept. Therefore, the conventional dental floss rod 1Although it can achieve the effect of cleaning teeth, there are still inconveniences, easy damage and waste of resources in actual use.

The right recessed areas 341 and 331 are connected to the left and right wire grooves 342 and 332. As for the adjustment member 2 2 is a male screw 2 1 2 at the front end portion of the holding portion 2 1 and is screwed with respect to the holding portion 21 as an axis. And the inner side edge of the front end of the adjusting member 22 can touch the left and right curved portions 323 and 3 丨 3. Furthermore, the adjusting member 22 has a blocking piece 221 extending from the lower edge, and is held by the adjusting member. When moving relative to the holding portion 21, it is prevented that dirt enters between the adjusting member 22 and the male screw 212 ', thereby hindering the movement of the adjusting member 22. Continuing to refer to the fourth figure, the dental floss 4 of the present invention is knotted with a node 42 at the two ends of a thread body 4 i, and then on the thread body 4 between the two nodes 42, and then it is flat and knotted. At point 43, you can use the node 43 on the thread body 41 to more easily remove the dirt on the tooth interface; however, the aforementioned dental floss 4 series can be composed of nodes 42 and nodes on the long line 44 as shown in the fifth figure. 43, then cut at the appropriate place to form dental floss 4. Printed by the Consumer Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs. Refer to the second and fourth figures.

At this time, the left and right support parts 32 and 31 of the left and right support arms 32 and 31 are pivoted by the left and right parts respectively. 321 and 3 11 are swung outwards with the center as the center, and will be placed on the left and right hooks. 34 Page 7 Feng, the scale of the scale is applicable to China National Standard (CNS) A4 (210 X 297 mm) 483748 A7 Printed by the Consumer Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs. 5. Description of the Invention (6), the dental floss 4 on 33 can be tightened to remove tartar, and because the dental floss 4 and the holding part 21 are in a nearly vertical state. , So It is easy to remove the tartar between the teeth between the sides of the mouth. As for the tartar between the incisors, because the left and right floor holding portions 322, 3 1 2 and the holding portion 21 are located outside the oral cavity, it is convenient to change the angle and still To easily remove tartar, therefore, the floss holder 2 of this embodiment has the function of convenient operation; however, the aforementioned stopper 216 provided between the left and right curved portions 323 and 313 is to prevent the left and right curved portions 323, 313 causes excessive deformation due to improper use by the user, which damages the left and right floor arms 32 and 31. Therefore, when the left and right curved parts 323 and 313 are formed by a certain amount of indentation by the adjustment member 22, that is, Restricted by the stopper 216, it is no longer retracted to avoid damage to the left and right support arms 32, 3; further, because the holding portion 2 1 of the dental floss holder 2 has an accommodation space 2 inside 1 3, therefore, a large number of dental floss 4 can be placed in the accommodation space 2 1 3 to facilitate the acquisition and replacement of the dental floss 4. As for the design of the replaceable dental floss 4 in this embodiment, the dental floss holder 2 can continue to be used ' It can improve the lack of conventional dental floss sticks that are discarded after use. Cheaper than the conventional grid of 4 to floss floss pick, not only has economic benefits, even take a reduced waste of resources and environmental benefits with the person. > Please refer to the seventh figure, the structure of the dental floss holder 5 of this embodiment is roughly the same as that of the previous embodiment, and will not be described in detail. The dental floss holder 5 of this embodiment also includes a holding portion 51 and a tooth. The wire support member 52 and an adjustment member 53; the main difference from the front-embodiment lies in that the adjustment member 53 has a push-out portion 531 in front, and the push-out portion 531 can push the left and right curved portions M ], 522 are close to the left and right pivot joints 523, 524.. ^ Respectively, when the left and ____g 8 pages, this paper size applies to China National Standard (CNS) A4 (210 X 297 public love) (Please read the back first Please pay attention to this page and fill in this page again)-Order 1-line · 483748 A7 V. Description of the invention (7) When the dental floss 6 is hooked on the right hooks 525 and 526, and the adjusting member 53 is rotated, please < Read the precautions on the back and fill in this page again.) Move in the direction shown by the arrow, then the pusher 531 at the front end of the adjustment member 53 immediately pushes the left and right curved parts 521 and 522 inwardly. At this time, the left and right support parts 527, 528 is to swing outward with the left and right pivot joints 523 and 524 as the center, and the dental floss 6 is tightened as shown in the eighth figure. This embodiment can also replace dental floss 6 in a timely manner, which has the effect of reducing waste of resources and environmental protection. At the same time, because dental floss 6 and grip 5 are approximately orthogonal, it is easy to remove and it is convenient to clean the mouth. The tooth gap on the side is convenient to use. As described above, the present invention can rotate the adjusting member to link the left and right hooks at the front end of the left and right floor arms to expand or retract, thereby the tooth The dental floss is used tightly or relaxed after use to facilitate timely replacement of the dental floss, which has economic benefits and environmental protection, and the dental floss plaque behind teeth # T 琛 supports the lineage to form an approximately orthogonal appearance, which is convenient for oral cavity.
