[0038] In order to facilitate the breaking of the upper end of the cotton swab rod 6, a breaking groove is provided on the upper side of the cotton swab rod 6.

[0039] In use, the cotton swab rod 6 is installed in the sliding box 3, and the plurality of cotton swab rods 6 store plaque staining agents therein, the guide column 18 is located at the intersection of the first arc-shaped groove 13 and the second vertical groove 16 on the left side, the sliding column 11 is located at the intersection of the V-shaped groove 8 and the C-shaped ring groove 9 on the right side, the lower end of the cotton swab rod 6 in the frontmost sliding box 3 does not protrude out of the lower dust cover 36, one side wall of the stop rod 32 is in contact with the side wall of the hollow groove, the free end of the stop rod 32 protrudes into the first vertical groove 14 or the second vertical groove 16, the compression spring 31, the spring 25 and the torsional spring 33 are all in a natural state, the pointed toothbrush 20 and the V-shaped toothbrush 21 are folded and placed in the storage box 19, and the upper end of the storage box 19 is covered with the initial state of the upper dust cover 34.

[0040] When the patient needs to clean the orthodontic teeth, the patient presses the pressing plate 30 downward, the pressing plate 30 drives the pressing rod 17, the guide rod 29 and the guide column 18 to move downward and compresses the compression spring 31, under the blocking action of the stop rod 32, the guide column 18 can only slide into the first arc-shaped groove 13 on the left side, at the same time, the driving cylinder 2 generates clockwise rotation, the cylinder 2 drives the plurality of sliding boxes 3 to rotate synchronously, the frontmost sliding column 11 slides into the V-shaped groove 8 and drives the sliding box 3 to move downward, the cotton swab rod 6 moves downward with the sliding box 3, at the same time, the gear 28 rotates with the teeth in meshing, and the rack 26 is in meshing with the teeth to extrude the upper end of the cotton swab rod 6, with the rotation of the cylinder 2, the rack 26 gradually extrudes the cotton swab rod 6 and makes the upper end of the cotton swab rod 6 break from the breaking groove, the plaque staining agent in the cotton swab rod 6 flows on the cotton wool sleeve 7, and the lower end of the frontmost cotton swab rod 6 gradually protrudes out of the rectangular groove (see the attached drawings Figure 2 );

[0041] When the compression spring 31 is compressed to the limit, the guide column 18 slides to the intersection of the first arc-shaped groove 13 on the left and the lower end of the first vertical groove 14, and the pressing plate 30 is released, at which time the pressing rod 17 drives the guide rod 29 and the guide column 18 to move upward under the action of the compression spring 31, and squeezes the stop lever 32, which swings into the first arc-shaped groove 13 on the right and compresses the torsion spring 33. When the guide column 18 slides to the intersection of the first vertical groove 14 and the upper end of the first arc-shaped groove 13 on the right, the stop lever 32 resets under the action of the torsion spring 33 (see the attached drawings Figure 10 ), and at the same time, the frontmost slide column 11 slides to the lower end of the V-shaped groove 8, and the frontmost absorbent cotton sleeve 7 completely extends out of the lower dust cover 36. The patient holds the barrel 1 and uses the cotton swab rod 6 to drive the absorbent cotton sleeve 7 to dye the positions between the teeth, tooth gaps, biting surfaces, and the upper and lower sides of the metal braces and the teeth. Since the lower end of the cotton swab rod 6 is flat, it can effectively dye the positions between the steel wires on the braces and the teeth. After dyeing, the patient pulls the cotton swab rod 6 downward, removes it from the slide box 3, and throws it into the trash can. The positions on the braces and teeth that are dyed with the plaque agent are where the plaque exists.

[0042] After removing the upper dust cover 34, the V-shaped toothbrush 21 is swung out of the storage box 19, and the patient's teeth and braces are brushed with toothpaste. The V-shaped design of the head of the V-shaped toothbrush 21 can more closely fit the braces, and clean the surface of the braces and the side of the contact between the braces and the teeth. After using the V-shaped toothbrush 21, the pointed toothbrush 20 is swung out to clean the positions between the teeth and the steel wires and the teeth. Until the positions dyed with the plaque dye are cleaned, finally, the pointed toothbrush 20 and the V-shaped toothbrush 21 are cleaned and placed in the storage box 19, and the upper dust cover 34 is closed to complete the cleaning of the orthodontic teeth and metal braces.

[0043] When the teeth need to be cleaned next time, repeat the above actions. Press the pressing plate 30 downward, and the pressing rod 17 drives the guide column 18 to slide downward. The guide column 18 enters the second vertical groove 16 along the first arc-shaped groove 13, and at the same time, the cylinder 2 drives the plurality of slide boxes 3 to rotate so that the frontmost slide column 11 slides upward into the C-shaped ring groove 9 from the left side of the V-shaped groove 8, and the slide column 11 adjacent to the right side of the frontmost slide column 11 slides into the bottom of the V-shaped groove 8, so that the new absorbent cotton sleeve 7 soaked with the plaque dyeing agent extends downward out of the lower dust cover 36. Release the pressing rod 17, and operate the cotton swab rod 6 to dye the teeth and braces to observe the distribution of plaque on the teeth and braces and improve the cleaning effect.

[0044] The angle formed between the projection of the first vertical groove 14 and the second vertical groove 16 adjacent to the first vertical groove 14 on the projection plane perpendicular to the axis of the cylinder body 1 and the center of the cylinder body 1 is 36°, the angle formed between the projection of any two second vertical grooves 16 adjacent to each other on the projection plane perpendicular to the axis of the cylinder body 1 and the center of the cylinder body 1 is 72°, and the angle formed between the projection of any one free end of the V-shaped groove 8 and the lower end of the V-shaped groove 8 on the projection plane perpendicular to the axis of the cylinder body 1 and the center of the cylinder body 1 is 36°, so that every time the user presses the pressing plate 30 downward, a new cotton swab rod 6 is extended from the rectangular groove for tooth plaque staining.

[0045] When all the cotton swab rods 6 in the slide box 3 are used up, the lower dust cover 36 is pulled off, the push rod 24 is pushed upward, the push rod 24 drives the push column to move upward and press the spring 25, the movable clamping plate gradually moves away from the fixed clamping block 4, the part of the cotton swab rod 6 that is broken at the upper end is removed from the slide box 3 and falls off, and a new cotton swab rod 6 is inserted into the slide box 3 and located between the movable clamping plate and the fixed clamping block 4. The push rod 24 is released, and the push rod 24 moves downward under the action of the spring 25, so that the movable clamping block 5 and the fixed clamping block 4 clamp the cotton swab rod 6. The above operation is repeated to load new cotton swab rods 6 into the plurality of slide boxes 3.

[0046] The cotton swab rod 6 is hollow and has a plaque staining agent inside. After the cotton swab rod 6 is broken at the upper end, the plaque staining agent is soaked in the lower end of the cotton swab. This principle uses the principle of a disposable iodophor cotton swab, which is a prior art and will not be described in detail.

[0047] During the process that the slide column 11 slides downward from the C-shaped ring groove 9 into the lower end of the V-shaped groove 8, the gear 28 meshes with the teeth to drive the rack 26 to press the upper end of the cotton swab rod 6. When the upper end of the cotton swab rod 6 is broken, the gear 28 is disengaged from the teeth, and the gear 28 remains in the current state after disengaging from the teeth without external force acting on the damping shaft 27. During the process that the slide column 11 slides upward from the lower end of the V-shaped groove 8 into the C-shaped ring groove 9, the gear 28 moves upward with the slide box 3, and when the gear 28 approaches the teeth, the gear 28 meshes with the teeth and drives the rack 26 to move away from the cotton swab rod 6 to reset.
