[0024] The present invention will be further described below in conjunction with specific embodiments. It should be understood that these embodiments are only used to illustrate the present invention and are not intended to limit the scope of the present invention. In addition, it should be understood that after reading the content taught by the present invention, those skilled in the art can make various changes or modifications to the present invention, and these equivalent forms fall within the scope limited by the appended claims of the application equally. Example 1

[0025] like Figure 2-4 As shown, the present embodiment provides a dental flosser specifically for orthodontics, comprising a hand-held portion, a dental floss receiving and releasing portion 2, a dental floss threading portion 1, a clamping mechanism 3, a dental floss tightening mechanism 5, and a dental floss cutting mechanism 4, wherein the clamping mechanism 3, the dental floss tightening mechanism 5, and the dental floss cutting mechanism 4 are arranged on the side of the hand-held portion and are located on the same axis, and the dental floss receiving and releasing portion 2 and the dental floss threading portion 1 are respectively arranged at the rear end and the front end.

[0026] The dental floss threading and winding auxiliary device of this embodiment integrates the functions of dental floss storage, dental floss fixing, dental floss cutting, and dental floss threading and winding around orthodontic archwires, making it convenient for people wearing dental braces to use dental floss and achieving repeated use.

[0027] like Figure 5-6Inspired by the conventional dental floss structure, the dental floss threading part 1 is improved, and the improved dental floss threading part 1 comprises a C-shaped fixing frame 101 and an I-shaped rotating rod 102, wherein the C-shaped fixing frame 101 is integrally formed with the hand-held part, and a clamping groove A105 and a clamping groove B106 with opposite opening directions are respectively provided at both ends of the C-shaped fixing frame 101, specifically, the opening direction of the clamping groove A105 is away from the C-shaped notch 103 of the C-shaped fixing frame 101, and the opening direction of the clamping groove B106 is toward the C-shaped notch 103 of the C-shaped fixing frame 101.

[0028] The “I” shaped rotating rod 102 has an integrally formed rotating shaft A107 and rotating shaft B108 at both ends, wherein the rotating shaft A107 is located in the clamping groove A105, and the rotating shaft B108 is located in the clamping groove B106. A threading loop 104 is provided at the front end of the rotating shaft A107, and the threading loop 104 bypasses the side wall of the clamping groove A105 and is located outside the clamping groove A105.

[0029] When in use, the orthodontic arch wire first contacts the rotation axis B108, and the handheld part continues to move forward. Then, due to the squeezing of the orthodontic arch wire on the rotation axis B108, the "I"-shaped rotating rod 102 rotates counterclockwise around the rotation axis A107 as a circle, and the orthodontic arch wire enters the C-shaped notch 103. At this time, the "I"-shaped rotating rod 102 is located above the orthodontic arch wire, and is reset after the contact with the rotation axis B108 is released. After the "I"-shaped rotating rod 102 is reset, it is located on the inner side of the orthodontic arch wire, that is, on the tongue side of the user; the handheld part is pulled back, the orthodontic arch wire contacts the rotation axis A107, and the rotation axis A107 carries the dental floss and rotates clockwise around the rotation axis B108 as the center, so that the dental floss is passed around the orthodontic arch wire. In this process, the "I"-shaped rotating rod needs to pass through the bottom of the orthodontic arch wire. Considering that the orthodontic arch wire is made of steel wire, the "I"-shaped rotating rod can be made of plastic or steel wire thinner than the orthodontic arch wire. At this point, the dental floss is passed under the orthodontic archwire to facilitate tooth care. Example 2

[0030] This embodiment mainly improves the dental floss receiving and releasing part 2, such as Figure 7 As shown, the dental floss storage portion includes a storage box 201, which is integrally formed with the hand-held portion. One side of the hand-held portion is opened, and a T-shaped winding shaft 202 and a T-shaped limit seat 203 are arranged inside the hand-held portion. The horizontal rod of the T-shaped limit seat 203 penetrates the horizontal axis of the T-shaped winding shaft 202 and then extends from the side of the storage box 201 and is threadedly connected to the handle 204. The dental floss is wound on the horizontal axis of the T-shaped winding shaft 202 and is restricted between the disc of the T-shaped winding shaft 202 and the disc of the T-shaped limit seat 203 to prevent the dental floss from being contaminated.

[0031] A compression spring A205 is provided between the handle 204 and the outer wall of the storage box 201 , one end of the compression spring A205 is connected to the outer wall of the storage box 201 , and the other end thereof is connected to the handle 204 .

[0032] The dental floss is fixed at the tail of the handheld part by using the compression spring A205, the T-shaped limit seat 203 and the T-shaped winding shaft 202. When not in use, the compression spring A205 pushes the handle 204 outward, so that the T-shaped limit seat 203 squeezes the T-shaped winding shaft 202, and the T-shaped winding shaft 202 is prohibited from rotating. When using the dental floss, the dental floss reserved in the wire outlet hole 206 is led out, and the handle 204 is pressed so that the coil can rotate and the dental floss is pulled out. When the dental floss is pulled out long enough, the handle 204 is released, and the dental floss between the T-shaped limit seat 203 and the T-shaped winding shaft 202 can be tightened to prevent the dental floss from being contaminated. Example 3

[0033] In this embodiment, the dental floss tightening mechanism 5 is improved on the basis of the embodiment 1. Figure 8-11 As shown, the dental floss tightening mechanism 5 includes a dental floss tightening seat 501, a wire fixing seat 502 and a movable seat 506. The side wall of the dental floss tightening seat 501 is provided with a threading hole 508 and a wire bundle groove A504, a mounting groove is provided on the top, the threading hole 508 is connected with the mounting groove, and a round table is provided at the bottom; the wire fixing seat 502 is arranged in the mounting groove, and a wire fixing hole 503 penetrating through the wall thickness is arranged along its horizontal line, and a compression spring C505 is arranged at the bottom of the wire fixing seat 502, and the compression spring C505 is respectively connected to the bottom of the wire fixing seat 502 and the bottom wall of the mounting groove; the movable seat 506 is arranged in the guide groove 8 of the side wall of the hand-held part, and is connected to the round table, and a reset spring A507 is arranged on the side wall, and the reset spring A507 is sleeved on the guide column in the guide groove 8 and connected to the side wall of the guide groove 8.

[0034] After passing through the wire bundle groove A504, the dental floss goes around the threading loop 104 and returns to pass through the threading hole 508 and the wire fixing hole 503 in sequence. After passing through the wire fixing hole 503, the wire fixing seat 502 is released. Under the action of the compression spring C505, the wire fixing hole 503 moves up. The dental floss can be fixed by utilizing the positional relationship between the dental floss tightening seat 501 and the wire fixing seat 502. The dental floss can be tightened by utilizing the dental floss storage box 201, the threading loop 104, the wire fixing hole 503 and the compression spring C505. Even if the dental floss moves with the "I"-shaped rotating rod 102, the dental floss tightening seat 501 is reciprocated in the guide groove 8 with the wire fixing seat 502, so the dental floss is always kept in a tightened state; and the dental floss is stretched according to a predetermined trajectory. Example 4

[0035] On the basis of Example 2, a clamping mechanism 3 is provided at the outlet end of the dental floss. Fig.12 and Fig.13As shown, the clamping mechanism 3 includes a clamping seat 301, a wire clamping groove 303 is horizontally arranged along the side wall of the clamping seat 301, and a through accommodating cavity 306 is arranged at the bottom of the wire clamping groove 303, and a movable opening 307 connected to the accommodating cavity 306 is also arranged on the side wall of the clamping seat 301.

[0036] An adjusting block 302 is arranged in the accommodating cavity 306, a toggle block 305 is arranged on the side wall of the adjusting block 302, the toggle block 305 extends out from the movable opening 307, two symmetrical compression springs B304 are arranged at the bottom of the adjusting block 302, one end of which is connected to the adjusting block 302, and the other end is connected to the top wall of the hand-held part.

[0037] When in use, the toggle block 305 is pressed to expose the wire clamping groove 303, and the dental floss is placed along the wire clamping groove 303. Then the toggle block 305 is released, the adjustment block 302 is reset, and the wire clamping groove 303 is blocked. The dental floss is fixed by utilizing the relative position of the adjustment block 302 and the clamping seat 301, and at the same time, the dental floss end led out of the dental floss receiving and releasing part 2 can be protected to avoid contamination.

[0038] Each time when using, pull the dental floss at the left end of the wire clamping groove 303 all the way, then pass the dental floss that is originally exposed outside the storage box 201 around the fixing hole and fix it, so that the dental floss on one side of the fixing loop is clean dental floss, ensuring the safety of dental floss use. Example 5

[0039] This embodiment mainly improves the dental floss cutting mechanism 4, such as Fig.14 and Fig.15 As shown, the dental floss cutting mechanism 4 includes a mounting seat 401 and a T-shaped extrusion block 402. A wire beam groove B403 is arranged on the side wall of the mounting seat 401, and a vertical groove 404 connected to the wire beam groove B403 is arranged on the top thereof. The T-shaped extrusion block 402 is arranged in the vertical groove 404, and a wire cutting blade 405 is arranged at the bottom, and a return spring B406 is sleeved on the outer side of the T-shaped pressure block. The return spring B406 is located between the horizontal wall of the T-shaped pressure block and the top of the mounting seat 401, and the two are connected.

[0040] After passing through the wire clamping groove 303, the dental floss passes through the wire bundle groove B403. At this time, the wire cutting blade 405 shrinks into the vertical groove 404 due to the action of the reset spring B406. When the dental floss passes through the orthodontic arch wire and needs to be cut, the T-shaped extrusion block 402 is squeezed. Since the dental floss is tightened, the falling wire cutting blade 405 easily cuts the dental floss. Example 6

[0041] like Fig.16 and Fig.17In this embodiment, the handheld part is divided into two parts, one end is the dental floss receiving part 2, and the other end is the dental floss winding part 1. The dental floss receiving part 2 and the dental floss winding part 1 are connected through a rotating mechanism 6. The rotating mechanism 6 includes a connecting shaft 601. The two ends of the connecting shaft 601 are respectively provided with threaded sections, which are respectively threadedly connected with the dental floss receiving part 2 and the dental floss winding part 1. A rotating cylinder 602 is sleeved on the connecting shaft 601, and a plurality of wire beam grooves C603 are provided on the side wall of the rotating cylinder 602. After the dental floss passes through the wire beam grooves C603, it passes through the dental wire coil. By rotating the rotating cylinder 602, the inclination direction of the dental floss can be adjusted, and the angle of the dental floss can be adjusted, so that the dental floss can pass through the orthodontic arch wires at the molars on both sides, which is more applicable.
