[0002] The principle of bracket correction is usually to use brackets to better fix the teeth to correct the crooked teeth. Orthodontic surgery is performed first. After completion, the appropriate bracket is selected according to the size, shape and degree of correction of the teeth. Then the archwire is installed and passed through the slot of each bracket. The archwire is usually made of stainless steel or nickel alloy. During the process of tooth correction, the archwire will apply continuous pressure to the teeth, causing the teeth to gradually move to the desired position.

[0003] Bracket locking tweezers are handheld tools that can clamp brackets, which are convenient for fixing the brackets. In the prior art, reverse tweezers are often used for clamping, which are small in size and suitable for use in the oral cavity. However, in actual applications, reverse tweezers are contrary to people's daily usage habits. Due to inertia, the tweezers will fall when the hands are squeezed, which is inconvenient to use. In addition, the bracket is small in size, and it is inconvenient to fix it only by the friction and clamping force of the tweezers. The bracket is easy to fall and needs to be re-clamped, which is inconvenient to operate, and there is room for improvement. Utility Model Content

[0022] The utility model is further described in detail below in conjunction with the accompanying drawings.

[0023] Embodiment 1, in combination with the attached Figure 1-2 A bracket locking forceps for orthodontics, comprising a support arm 1 and a support arm 2; a through slot 3 capable of accommodating the support arm 2 is provided at the middle end of the support arm 1, and a through hole is provided at the middle end of the support arm 1 and the support arm 2, and a rotating shaft is provided in the through hole for common rotation, and both ends of the rotating shaft extend out of the support arm 1 and are provided with a limit plate 4, so that the support arm 1 and the support arm 2 can rotate towards each other to achieve the clamping and release of the bracket.

[0024] Combined with Figure 1-2 The lower ends of the support arms 1 and 2 are provided with limiting rings 5, and the inner sides of the limiting rings 5 ​​are provided with anti-slip sleeves 6. The limiting rings 5 ​​are used to be put on the fingers, and the anti-slip sleeves 6 increase the friction between the fingers and the support arms 1 and 2, so that they are not easy to slip when used.

[0025] Combined with Figure 1-4 , the upper ends of the support arms 1 and 2 are both provided with bracket clamping assemblies, and the bracket clamping assemblies include limit clamps 7 on the upper ends and opposite sides of the support arms 1 and 2, the cross-sections of the limit clamps 7 are all L-shaped, and the outer sides of the limit clamps 7 are all arc-shaped, so that the corners are not easy to collide with other teeth and cause discomfort to the patient; the opposite sides of the limit clamps 7 are all arc-shaped surfaces, and the arc-shaped surfaces are all provided with a plurality of vertical grooves 8, which are convenient for clamping the brackets, and compared with the plane, the vertical grooves 8 can increase the stability of clamping and are not easy to slip; the lower ends of the limit clamps 7 are provided with supporting plates 9, and the opposite sides of the supporting plates 9 are all provided with arc-shaped notches 10, which can support the brackets and prevent them from falling due to the lack of support at the bottom; the arc-shaped notches 10 on the supporting plates 9 can reduce the area of ​​the supporting plates 9, so as to avoid the situation where the limit clamps 7 are not clamped tightly due to the contact and conflict between the supporting plates 9 when the brackets are small.

[0026] Embodiment 2, combined with the attached Figure 1-3 A mouth mirror assembly is provided on each of the support arms 1 and 2, and the mouth mirror assembly includes a groove 11 provided on each of the support arms 1 and 2, and a support rod 12 is rotatably provided in each of the grooves 11; an extension plate 13 is provided on the support rod 12, and a support rod 2 14 is rotatably provided on one end of the extension plate 13 away from the support rod 12, and a mouth mirror 15 is provided on the support rod 14; thereby, the mouth mirror 15 can change its inclination angle and the distance from the oral cavity in all directions by adjusting the position of the groove 11 and the support rod 12, and the position of the extension plate 13 and the support rod 2 14.

[0027] Combined with Figure 1-3, a rotation limiting structure is provided between the groove 11 and the support rod 12. The rotation limiting structure includes a serrated limiting strip provided on the outer side of the support rod 12, and a limiting tooth corresponding to the limiting strip is provided on the inner side of the groove 11. Thus, every time the support rod 12 rotates once, the support rod 12 only rotates a limited angle within the groove 11 and will not rotate randomly, playing a role of self-limitation.

[0028] Combined with the attached Figure 1-3 , a base capable of rotatably connecting with the second support rod 14 is provided on the extension plate 13. The second support rod 14 is in close contact with the base. Therefore, it takes force for the second support rod 14 to rotate within the base, which is synonymous with the above rotation limiting structure and plays a role of self-limitation to a certain extent.

[0029] Combined with the attached Figure 1 , anti-slip patterns are provided on the outer sides of the extension plate 13 and the mouth mirror 15. Due to its small volume, setting the anti-slip patterns can increase the friction with the hand and facilitate rotation.

[0030] The working principle of the present utility model: When in use, the bracket is placed between the two limiting members 7, and the first support arm 1 and the second support arm 2 are pinched to clamp the bracket. The support plate 9 plays a role of supporting the bottom of the bracket; during positioning, rotating the support rod 12 within the groove 11 can adjust the distance between the mouth mirror 15 and the oral cavity, and rotating the second support rod 14 on the extension plate 13 can adjust the tilt angle of the mouth mirror 15, facilitating the observation of the horizontal position and tilt angle of adjacent brackets, etc., and facilitating the auxiliary positioning of the bracket.

[0031] The above has described the present utility model and its implementation manners. Such description is not restrictive. What is shown in the drawings is only one of the implementation manners of the present utility model, and the actual structure is not limited thereto. Generally speaking, if those of ordinary skill in the art are inspired by it and design similar structural manners and embodiments without creative work without departing from the creative purpose of the present utility model, they should all fall within the protection scope of the present utility model.
