DETAILED DESCRIPTION

[0021] In order to further understand the content of the present invention, the present invention is described in detail with reference to the accompanying drawings and embodiments. It should be understood that the embodiments are merely for explanation of the present invention and are not intended to limit the present invention.

[0022] The following is combined with Figures 1-4 This embodiment is described in further detail.

[0023] See also Figures 1-4 In this embodiment, a groove of an orthodontic bracket includes a groove part 3 provided in a bracket body 1, a mounting groove 2 for placing the groove part 3 is provided in the bracket body 1, an archwire groove 4 for installing an archwire is provided in the groove part 3, and fixing holes 5 are provided on both sides of the archwire groove 4. Square grooves 6 are provided in the bracket body 1 and on both sides of the mounting groove 2. A circular cavity 7 is provided in the square groove 6. A telescopic rod 8 that penetrates the bottom wall of the circular cavity 7 and can be extended into or out of the fixing hole 5 is provided in the square groove 6. A control component for controlling the telescopic rod 8 to extend into or out of the fixing hole 5 is provided in the square groove 6.

[0024] In actual use of this embodiment, the bottom end of the bracket body 1 is provided with a mesh bottom 9 bonded to the surface of the tooth, thereby achieving fixation of the bracket body 1 on the tooth.

[0025] In this embodiment, the bracket body 1, the mounting slot 2, the groove member 3, and the archwire slot 4 are arranged so that when orthodontic treatment is performed on the patient's teeth, the bracket body 1 is fixed to the tooth surface through the mesh bottom 9, the groove member 3 is slidably installed in the mounting slot 2, and then the archwire is installed in the archwire slot 4.

[0026] In this embodiment, the telescopic rod 8 is slidably installed in the circular cavity 7 through the arrangement of the fixing hole 5, the square groove 6, the circular cavity 7, the telescopic rod 8 and the control component, and one end of the telescopic rod 8 can penetrate the bottom wall of the circular cavity 7 and extend into the installation groove 2, and the other end extends into the square groove 6; when the groove member 3 installed in the installation groove 2 is installed, the groove member 3 is placed in the installation groove 2, and then the end of the telescopic rod 8 is driven by the control component to extend into the fixing hole 5, and the groove member 3 can be installed. Since the telescopic rod 8 extends into the fixing hole 5, the telescopic rod 8 limits the groove member 3, so that the groove member 3 cannot be displaced in the bracket body 1, thereby avoiding affecting the correction effect.

[0027] See also Figures 1-4 In this embodiment, the control component includes a slidable block 100 arranged in the square groove 6. The side of the block 100 is provided with an upper plane 101 for squeezing the telescopic rod 8 into the fixing hole 5. The side of the block 100 is provided with a lower plane 102. Between the upper plane 101 and the lower plane 102 is provided a guide inclined surface 103 for allowing one end of the telescopic rod 8 to slide along the upper plane 101 to the lower plane 102 to disengage the telescopic rod 8 from the fixing hole 5.

[0028] In this embodiment, the block 100, the upper plane 101, the lower plane 102 and the guiding inclined surface 103 are arranged so that the block 100 is slidably connected to the square groove 6. When the block 100 slides in the square groove 6, when the upper plane 101 of the block 100 abuts against the end of the telescopic rod 8 extending into the square groove 6, the other end of the telescopic rod 8 can be extended into the fixing hole 5, thereby limiting the groove member 3 located in the mounting groove 2. When the end of the block 100 extending into the square groove 6 slides from the upper plane 101 along the guiding inclined surface 103 to the lower plane 102 and abuts against the lower plane 102, the other end of the telescopic rod 8 can be detached from the fixing hole 5, thereby releasing the limitation of the telescopic rod 8 on the groove member 3.

[0029] Among them, the end of the telescopic rod 8 extending into the square groove 6 is arc-shaped, and an arc-shaped groove for the end of the telescopic rod 8 extending into the square groove 6 is provided at the center of the upper plane 101 and the lower plane 102. The end of the telescopic rod 8 extending into the square groove 6 can slide into or out of the arc-shaped groove, thereby better making the end of the telescopic rod 8 extending into the square groove 6 abut against the upper plane 101 and the lower plane 102.

[0030] See also Figures 1-4In this embodiment, a ring 104 is provided at the open end of the circular cavity 7 for allowing one end of the telescopic rod 8 to extend into the square groove 6, a pressure ring 105 is provided on the telescopic rod 8, and an elastic member 106 is provided on the telescopic rod 8 between the pressure ring 105 and the bottom wall of the circular cavity 7 for pushing the telescopic rod 8 to slide along the guide inclined surface 103. A square plate 107 is provided at the open end of the square groove 6 for blocking the square groove 6, a movable groove 108 is opened on the square plate 107, and a dial hole 109 is provided on the block 100 for pushing the block 100 to slide.

[0031] In this embodiment, the collar 104, the pressure ring 105, and the elastic member 106 are arranged so that the collar 104 is threadedly connected to the open end of the circular cavity 7 to facilitate the installation of the internal components of the circular cavity 7. The pressure ring 105 is fixedly connected to the telescopic rod 8 and is slidably connected to the inner wall of the circular cavity 7. The telescopic rod 8 passes through the center of the collar 104 and is slidably connected to the collar 104. The elastic member 106 is sleeved on the telescopic rod 8 between the pressure ring 105 and the bottom wall of the circular cavity 7. The elastic member 106 can push the pressure ring 105 to drive the end of the telescopic rod 8 extending into the square groove 6 to slide from the upper plane 101 along the guide slope 103 to the lower plane 102, thereby disengaging the telescopic rod 8 from the fixing hole 5 and simultaneously generating compression between the telescopic rod 8 and the block 100, so that the block 100 requires external force to move. The elastic member 106 can be elastic rubber.

[0032] In this embodiment, by setting the square plate 107, the movable groove 108 and the shifting hole 109, the square plate 107 is fitted with the block 100 and the block 100 and the square plate 107 are slidably connected. By inserting the probe in the dental instrument into the shifting hole 109, the block 100 is pushed to slide, so that the end of the telescopic rod 8 extending into the square groove 6 is located on the upper plane 101 or the lower plane 102, thereby driving the other end of the telescopic rod 8 to extend into the fixing hole 5 or detach from the fixing hole 5, thereby preferably completing the installation of the groove member 3.

[0033] See also Figures 1-4 In this embodiment, an insertion hole 200 is provided on the side opposite to the mounting slot 2 and passes through one side of the bracket body 1. An insertion plate 201 for blocking the archwire slot 4 is provided in the insertion hole 200, and a bending piece 202 for fixing the insertion plate 201 is provided opposite to the side opening of the bracket body 1.

[0034] In this embodiment, the arrangement of the socket 200, the inserting plate 201, and the bending piece 202 allows the inserting plate 201 to be slidably connected to the socket 200, that is, the inserting plate 201 can be inserted into the socket 200. One end of the bending piece 202 is fixedly connected to the bracket body 1 and is bendable. When installing the inserting plate 201 in the socket 200, the bending piece 202 is first bent to allow the inserting plate 201 to be inserted into the socket 200. When the inserting plate 201 is fully inserted, the bending piece 202 is bent so that it blocks the opening of the socket 200, thereby limiting the position of the inserting plate 201 and fixing it in the socket 200, completing the installation of the inserting plate 201. The bending piece 202 can be made of a deformable metal material that is harmless to the human body.

[0035] Working principle: When the groove of the orthodontic bracket is in use, the block 100 is pushed to slide by inserting a probe in the dental instrument into the dial hole 109. The sliding of the block 100 drives the end of the telescopic rod 8 to extend into the square groove 6 and abut against the lower plane 102 of the block 100, so that the telescopic rod 8 retracts into the circular cavity 7 so that the groove member 3 can be placed in the installation groove 2. After the groove member 3 is placed, the probe in the dental instrument is inserted into the dial hole 109 again to push the block 100 to slide, driving the end of the telescopic rod 8 to extend into the square groove 6 and abut against the upper plane 101 of the block 100, so that the telescopic rod 8 extends into the fixing hole 5, and the installation of the groove member 3 is completed for use.
