DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0027] The invention will be further described in detail hereinafter with reference to the drawings.

[0028] With reference to FIG. 1-6, a dental floss stick, comprising an upper piece 1 and a lower piece 2, wherein both the upper piece 1 and the lower piece 2 are U-shaped; the top of both ends of the opening of the upper piece 1 and the top of both ends of the opening of the lower piece 2 are rotatably connected; the upper part of both ends of the opening of the upper piece 1 is provided with a bulge 3, and the upper part of both ends of the opening of the lower piece 2 is provided with a groove 4 corresponding to the bulge 3;

[0029] the middle part of the upper piece 1 is provided with a female buckle 5, and the middle part of the lower piece 2 is provided with a male buckle 6 matching the female buckle 5;

[0030] the upper part of both ends of the opening of the upper piece 1 is provided with a dental floss 7; the dental floss 7 is wound on the upper piece 1, and the winding place of the dental floss 7 and the upper piece 1 is located on the upper side of the bulge 3;

[0031] the upper part of either end of the opening of the lower piece 2 is provided with a blade 8; the blade 8 is located at the groove 4, and the blade 8 has the function of cutting the dental floss 7;

[0032] the middle part of the upper piece 1 is provided with a handle 9.

[0033] The blade (8) is located outside the lower piece 2.

[0034] The width of the blade 8 increases linearly from the rotating joint between the upper piece 1 and the lower piece 2 to the other end.

[0035] The blade 8 and the lower piece 2 are connected and fixed by threads.

[0036] The material of the blade 8 is carbon steel.

[0037] The middle part of the lower piece 2 is provided with a wrench 10.

[0038] The material of the dental floss 7 is high molecular weight polyethylene fiber.

[0039] The material of the upper piece 1 is food-grade plastic.

[0040] The material of the lower piece 2 is food-grade plastic.

[0041] When the invention is implemented in specific use, the dental floss 7 can be tied to the upper piece 1, and the dental floss stick is used normally.

[0042] When the dental floss stick is used up, rotate the lower piece 2 and when the lower piece 2 rotates, the blade 8 will also rotate, and then the dental floss 7 tied to the upper piece 1 is cut off. It is convenient to remove the dental floss 7 from the lower piece 2.

[0043] After removing the dental floss 7, when not in use, turn the lower piece 2 to overlap the upper piece 1; at this time, the bulge 3 at the upper part of both ends of the opening of the upper piece 1 and the groove 4 at the upper part of both ends of the opening of the lower piece 2 are matched. The male buckle 6 and the female buckle 5 cooperate to prevent the lower piece 2 and the upper piece 1 from rotating.

[0044] When using it again, use your fingers to squeeze the wrench 10, the lower piece 2 and the upper piece 1 will rotate, and the male buckle 6 and the female buckle 5 will separate; then tie the dental floss 7 to the upper piece 1, and the blade edge of the blade 8 is attached to the dental floss 7, so it can be used normally.

[0045] The invention has simple structure and convenient use. It is convenient to replace dental flosses, which avoids waste of dental floss sticks, and has high practical value and promotion value.

[0046] The invention and its embodiments are described hereinabove, and the description is not restrictive. What is shown in the drawings is only one of the embodiments of the invention and the actual structure is not limited thereto. All in all, structural modes and embodiments similar to the technical solution without deviating from the inventive purpose of the invention made by those of ordinary skill in the art without creative design shall all fall within the protection scope of the invention.
