[0007] The first tweezer neck is connected to the first tweezer tip, the second tweezer neck is connected to the second tweezer tip, and each of the first and second tweezer tips is provided with a clamping part, with the clamping edges of the two clamping parts facing each other.

[0008] A positioning mechanism is provided between the first and second forceps arms, between the first and second forceps necks, and between the first and second forceps tips. The positioning mechanism includes a drive assembly and a scale blocking assembly connected to the drive assembly. The scale blocking assembly abuts against the occlusal surface of the teeth. The ends of the first and second forceps tips are provided with scales for measuring the position of the brackets.

[0009] As a further improvement to the technical solution of the present invention, the ruler blocking assembly includes a ruler blocking block and a connecting rod connected to the ruler blocking block, the other end of the connecting rod being connected to a drive assembly; the ruler blocking block abuts against the occlusal surface of the tooth.

[0010] As a further improvement to the technical solution of the present invention, the connecting rod is a long strip-shaped rod structure.

[0011] As a further improvement to the technical solution of the present invention, the driving component includes a dial wheel, a dial wheel limiting clamp, a dial wheel positioning pin, a crank, and a limiting hole block.

[0012] The dial positioning pin passes through the center of the dial, and the two ends of the dial positioning pin are respectively connected to the inner walls of the first tweezer arm and the second tweezer arm;

[0013] One end of the dial wheel limiting clamp is fixed to the first tweezer arm and the second tweezer arm, and the other end is connected to the dial wheel;

[0014] One end of the crank is connected to the derailleur, and the other end of the crank is connected to the end of the connecting rod;

[0015] The limiting hole block is fixed between the first tweezer arm and the second tweezer arm, and the connecting rod passes through the middle of the limiting hole block.

[0016] As a further improvement to the technical solution of the present invention, a first opening is provided at the center of the dial wheel, and the dial wheel positioning pin passes through the first opening.

[0017] As a further improvement to the technical solution of the present invention, the dial wheel has arc-shaped grooves on both sides, and the dial wheel limiting clamp includes two clamping parts and a fastening structure provided on the two clamping parts. The two clamping parts are located outside the two sides of the dial wheel, and the fastening structure is recessed into the groove.

[0018] As a further improvement to the technical solution of the present invention, the drive assembly further includes a pin, one end of the crank is connected to the dial wheel through the pin, and the other end of the crank is connected to the end of the connecting rod through the pin.

[0019] As a further improvement to the technical solution of the present invention, a locking block is provided on the inner side of the end of the first tweezer tip and the second tweezer tip, and the locking block engages with the groove of the bracket.

[0020] As a further improvement to the technical solution of the present invention, the surfaces of the first and second tweezer arms are provided with anti-slip textures.

[0021] As a further improvement to the technical solution of the present invention, the dial is circular, and the outer contour surface of the dial is provided with a toothed structure.

[0037] The present invention will now be described in detail.

[0038] To make the objectives, features, and advantages of the present invention more apparent and understandable, specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. Several embodiments of the present invention are shown in the drawings. However, the present invention can be implemented in many different forms and is not limited to the embodiments described herein.

[0039] In this invention, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances. The terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined with "first" or "second" may explicitly or implicitly include one or more of that feature.

[0040] In this invention, unless otherwise expressly specified and limited, "above" or "below" a second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of a second feature includes the first feature being directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" of a second feature includes the first feature being directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature. The terms "vertical," "horizontal," "left," "right," "above," "below," and similar expressions are for illustrative purposes only and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed or operated in a specific orientation, and therefore should not be construed as limiting the invention.

[0041] like Figure 1-11As shown, a bracket tweezer with a positioning structure includes a tweezer head 110, a first tweezer arm 200 and a second tweezer arm 300 connected to both sides of the tweezer head 110, the first tweezer arm 200 connected to a first tweezer neck 220, the second tweezer arm 300 connected to a second tweezer neck 320, and the first tweezer neck 220 and the second tweezer neck 320 intersect in space.

[0042] The first tweezer neck 220 is connected to the first tweezer tip 230, and the second tweezer neck 320 is connected to the second tweezer tip 330. The first tweezer tip 230 and the second tweezer tip 330 are each provided with a clamping part, and the clamping edges of the two clamping parts are arranged facing each other.

[0043] A positioning mechanism 400 is provided between the first forceps arm 200 and the second forceps arm 300, between the first forceps neck 220 and the second forceps neck 320, and between the first forceps tip 230 and the second forceps tip 330. The positioning mechanism 400 includes a driving component and a scale blocking component 407 connected to the driving component. The scale blocking component 407 abuts against the occlusal surface of the teeth. The ends of the first forceps tip 230 and the second forceps tip 330 are provided with scales for measuring the position of the bracket 700.

[0044] In this embodiment, the first forceps arm 200 and the second forceps arm 300 are the main gripping parts for the operator. Since the positioning structure of the bracket forceps is a reverse clamping structure, the reverse clamping of the first forceps arm 200 and the second forceps arm 300 has a pre-set force, which allows the two clamping blades to approach or abut against each other. The bracket 700 can be stably clamped by the two clamping blades without the need for other external forces. The operator can perform the surgery by lightly picking up the bracket forceps with the positioning structure. Even if the operator switches hands midway, there is no need to be careful, and the operator can concentrate more on bonding the bracket.

[0045] More specifically, the surfaces of the first tweezer arm 200 and the second tweezer arm 300 are provided with anti-slip textures 600, which can prevent the operator from slipping when applying force.

[0046] When the operator applies force to the anti-slip texture 600 of the first tweezer arm 200 and the second tweezer arm 300, the first tweezer arm 200 and the second tweezer arm 300 move closer to each other. Since the bracket tweezers have a reverse clamping structure, the first tweezer tip 230 and the second tweezer tip 330 move further apart from each other. At this time, the bracket 700 can be placed between the blades of the two clamps.

[0047] At this point, the operator no longer needs to apply force to the anti-slip texture 600 of the first tweezers arm 200 and the second tweezers arm 300. The first tweezers arm 200 and the second tweezers arm 300 have a pre-set force for reverse clamping, and the bracket 700 can be stably clamped by the two clamp blades without the need for other external forces.

[0048] More importantly, the present invention provides a positioning mechanism 400, which includes a driving component and a scale blocking component 407 connected to the driving component. The driving component can drive the scale blocking component 407 to reciprocate within the bracket forceps, thereby causing the scale blocking component 407 to abut against the occlusal surface 800a of the tooth. Figure 10-11 As shown, the ends of the first tweezer tip 230 and the second tweezer tip 330 are provided with scales for measuring the position of the bracket.

[0049] With the above-described configuration, the ruler blocking component 407 abuts against the occlusal surface 800a of the tooth, stabilizing the position of the bracket forceps and providing them with support during bracket bonding. Furthermore, the graduations at the tips of the first and second forceps 230 allow for precise control of the bracket bonding position, resulting in more accurate placement of the bracket 700 on the tooth surface 800 and improved orthodontic outcomes.

[0050] Furthermore, such as Figure 3-11 As shown, the scale blocking assembly 407 includes a scale blocking block 407a and a connecting rod 407b connected to the scale blocking block 407a. The other end of the connecting rod 407b is connected to a drive assembly. The scale blocking block 407a abuts against the occlusal surface 800a of the tooth. The connecting rod 407b is a long, rod-shaped structure.

[0051] In this embodiment, the ruler blocking block 407a is a block-shaped structure, and its contact point with the occlusal surface 800a is essentially a plane. This allows for better positioning of the bracket 700 on the occlusal surface 800a of the tooth 800. The elongated rod-shaped connecting rod 407b connects to the drive assembly, which drives the connecting rod 407b to reciprocate within the bracket forceps, thereby adjusting its position to suit different occlusal surfaces 800a.

[0052] Specifically, the drive assembly includes a dial 401, a dial limit clamp 402, a dial positioning pin 403, a crank 404, and a limit hole block 406.

[0053] The dial positioning pin 403 passes through the center of the dial 401, and the two ends of the dial positioning pin 403 are respectively connected to the inner walls of the first tweezer arm 200 and the second tweezer arm 300.

[0054] One end of the dial limit clamp 402 is fixed to the first tweezer arm 200 and the second tweezer arm 300, and the other end is connected to the dial 401;

[0055] One end of crank 404 is connected to dial 401, and the other end of crank 404 is connected to the end of connecting rod 407b;

[0056] The limiting hole block 406 is fixed between the first tweezer arm 200 and the second tweezer arm 300, and the connecting rod 407b passes through the middle of the limiting hole block 406.

[0057] In this embodiment, the dial 401 can rotate around its axis, the dial limit clamp 402 can limit the dial 401, the dial positioning pin 403 is located at the axis of the dial 401, and the dial positioning pin 403 rotates simultaneously with the dial 401.

[0058] One end of the crank 404 is connected to the eccentric part of the dial 401, and the other end of the crank 404 is connected to the end of the connecting rod 407b. When the dial 401 rotates around its axis, it can drive the crank 404 to rock, which in turn drives the connecting rod 407b to reciprocate within the bracket tweezers. This setting utilizes the crank-rocker principle, which will not be described in detail here.

[0059] The limiting hole block 406 is used to limit the connecting rod 407b, so that it can only reciprocate within the bracket tweezers.

[0060] Furthermore, a first opening 401a is provided at the center of the dial 401, through which the dial positioning pin 403 passes. Arc-shaped grooves 401c are provided on both sides of the dial 401. The dial limiting clamp 402 includes two clamping parts 402b and a fastening structure 402a provided on the two clamping parts 402b. The two clamping parts 402b are located outside the two sides of the dial 401, and the fastening structure 402a is recessed into the groove 401c.

[0061] In this embodiment, the two clamping parts 402b are placed on the outside of the two sides of the dial wheel 401, and the locking structure 402a is embedded in the groove 401c. With this arrangement, the dial wheel 401 can be better limited by the locking structure 402a and the groove 401c to prevent it from deviating.

[0062] Specifically, the drive assembly also includes a pin 405. One end of the crank 404 is connected to the dial 401 via the pin 405, and the other end of the crank 404 is connected to the end of the connecting rod 407b via the pin 405. The connection via the pin 405 is simple and direct.

[0063] like Figure 6-11 As shown, the inner side of the ends of the first tweezer tip 230 and the second tweezer tip 330 is provided with a locking block 500, which engages with the groove of the tray. The shape and size of this locking block 500 are adapted to the shape and size of the groove of the tray 700. The locking block 500 can be inserted into the groove of the tray 700. With this configuration, the tray 700 can be stably clamped by the two tweezer blades without the need for other external forces. Furthermore, the mutual limiting effect between the locking block 500 and the groove of the tray 700 prevents the tray 700 from deflecting in the clamped state. Finally, the end scales of the first tweezer tip 230 and the second tweezer tip 330 can precisely control the position of the adhesive tray 700.

[0064] Furthermore, the dial 401 is circular, and its outer contour surface has a toothed structure. This toothed structure enhances friction, preventing the dial 401 from slipping when the operator rotates it.

[0065] More specifically, such as Figure 7 and 9 As shown, to make the position of the adhesive bracket more accurate, a scale is set, where a represents the starting point of the scale, b represents 1mm, c represents 2mm, d represents 3mm, e represents 4mm, f represents 5mm, and g represents 6mm.

[0066] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the implementation of the present invention. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the scope of protection of the claims of the present invention.
