Description

Technical Field

[0001] The utility model relates to the technical field of oral tooth correction fixtures, in particular to an orthodontic clasp bending tool. Background Art

[0002] Orthodontic treatment is to meet aesthetic needs while maintaining the integrity of the tooth structure to the maximum extent possible and protecting the health of the gums; to enhance the health, function and aesthetics of the oral cavity, improve the patient's acceptance of oral treatment and enhance their confidence.

[0003] Through searching, it is found that the device of the interproximal hook bending pliers with announcement number: CN216933528U has a first wire groove arranged at the pliers mouth, which, on the one hand, can ensure the clamping of the wire with a diameter of 0.7-1mm, and on the other hand, can effectively prevent the wire from slipping on the working end face of the bending pliers. The upper edges of the first groove and the second groove of the present invention are spaced small from the top end of the pliers mouth, which, on the one hand, can ensure that the wire is not broken, and on the other hand, after the wire is clamped by the first wire groove, it can be bent toward the top end of the pliers mouth to form a 180-degree turn, thus ensuring that the wire is fully bent.

[0004] When correcting teeth, workers need to use various clamping tools to bend the wire into a specified shape. After the wire is fixed by the clamping tool, the worker needs to press the wire with his fingers to change its shape and curvature. Since the wire is thin and needs to be pressed repeatedly, it will cause damage and discomfort to the worker's fingers. To this end, we provide orthodontic clasp bending tools to solve the above problems. Utility Model Content

[0021] like Figure 1-Figure 4 As shown, an orthodontic clasp bending tool includes a pliers body 1, a connecting tube 5 is arranged above the pliers body 1, one end of the connecting tube 5 is rotatably mounted on the pliers body 1, and the other end is provided with a sliding rod 6, the connecting tube 5 and the sliding rod 6 are coaxially arranged, a vertical plate 7 is arranged at the end of the sliding rod 6 away from the connecting tube 5, a clamping plate 8 is arranged at the end of the vertical plate 7 close to the pliers body 1, a pressing plate 14 is arranged on the connecting tube 5, the pressing plate 14 is arranged in a "U" shape, and anti-slip pads are arranged on both sides of the pressing plate 14.

[0022] The vertical plate 7 and the slide bar 6 are slidably arranged, and a fastener 9 is arranged between the vertical plate 7 and the slide bar 6. The fastener 9 is arranged as an adjusting nut. By controlling the operation of the fastener 9, the fixation between the vertical plate 7 and the slide bar 6 is released, so that the vertical plate 7 can be driven to move on the slide bar 6, and the clamp 8 can be driven to follow the movement, and the distance between the clamp 8 and the pliers body 1 can be adjusted, or the vertical plate 7 and the clamp 8 can be replaced, and clamps 8 of different shapes can be installed on the slide bar 6 through the vertical plate 7, thereby increasing the application range of the device.

[0023] A guide groove 10 is provided in the connecting tube 5, and a limit plate 11 is fixedly installed on the slide rod 6. The slide rod 6 and the limit plate 11 are slidably installed in the guide groove 10. A fixing part is provided between the slide rod 6 and the connecting tube 5. By driving the slide rod 6 to move in the guide groove 10, the overall length between the slide rod 6 and the connecting tube 5 is adjusted, and the position of the splint 8 is adjusted. When the slide rod 6 moves, its moving direction is limited by the limit plate 11, thereby preventing the slide rod 6 from rotating when moving.

[0024] Two limit plates 11 are provided, and the two limit plates 11 are symmetrically installed on the slide rod 6, so that when the slide rod 6 is subjected to force, it can be stably transmitted to the connecting tube 5, so as to maintain the stability between the slide rod 6 and the connecting tube 5.

[0025] A threaded barrel 13 is provided between the pressing plate 14 and the connecting barrel 5. The pressing plate 14 is rotatably connected to the threaded barrel 13. The threaded barrel 13 is threadedly connected to the connecting barrel 5. When the staff rotates the threaded barrel 13, the threaded barrel 13 drives the pressing plate 14 to move on the connecting barrel 5, thereby adjusting the position of the pressing plate 14 to adapt to the habits of different personnel.

[0026] A mounting plate 2 is provided on the pliers body 1, a fixed shaft 3 is fixedly mounted on the mounting plate 2, a sleeve 4 is rotatably mounted on the fixed shaft 3, the sleeve 4 is fixedly connected to a connecting tube 5, and when the connecting tube 5 is rotated under force, the connecting tube 5 rotates around the axis of the fixed shaft 3 through the sleeve 4, and the connecting tube 5 is restricted on the pliers body 1 by the fixed shaft 3 and the mounting plate 2.

[0027] A positioning hole 16 is provided on the mounting plate 2, and a positioning cylinder 15 is provided in the positioning hole 16. One end of the positioning cylinder 15 is fixedly connected to the pliers body 1, and the other end is provided with a fixing bolt 12. The fixing bolt 12 is threadedly connected to the positioning cylinder 15. The fixing bolt 12 is driven and removed, thereby releasing the fixation of the mounting plate 2, so that the mounting plate 2 can be removed from the pliers body 1. During installation, the positioning cylinder 15 passes through the mounting plate 2, so that the position of the mounting plate 2 can be quickly located.

[0028] Working principle: When in use, the steel wire is fixed by the pliers body 1, and one end of the steel wire passes through the middle of the splint 8. Then the staff pushes the pressing plate 14 with their fingers according to the required bending angle. The pressing plate 14 drives the connecting tube 5 and the sleeve 4 to rotate around the axis of the fixed shaft 3. The connecting tube 5 rotates while driving the slide bar 6 to rotate. At the same time, the slide bar 6 drives the vertical plate 7 to move. The splint 8 on the vertical plate 7 applies a thrust to the steel wire, thereby bending the steel wire fixed on the pliers body 1. The pressing plate 14 increases the contact area with the staff's fingers, thereby avoiding damage to the staff's fingers caused by repeated manual bending of the steel wire and improving comfort.

[0029] When the clamping plate 8 needs to be replaced or the height needs to be adjusted, the staff manually controls the fastener 9 to work, thereby releasing the fixing restriction between the vertical plate 7 and the sliding rod 6, and then drives the vertical plate 7 to move on the sliding rod 6, or removes the vertical plate 7 and the clamping plate 8 from the sliding rod 6 for replacement, and then reversely controls the fastener 9 to work, thereby fixing the position of the vertical plate 7.

[0030] When the position between the slide rod 6 and the connecting tube 5 needs to be adjusted, the staff manually drives the control fixing part to work, releases the fixing restriction between the connecting tube 5 and the slide rod 6, and then pushes the slide rod 6 to move in the guide groove 10, and after reaching the preset position, drives the fixing part in reverse to work in reverse to fix it, thereby fixing the position of the slide rod 6.
