[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Example 1

[0024] Please see Figures 1 to 6 This utility model provides a technical solution: an adjustable orthodontic mouth opener, including: an arc-shaped rod 1, the arc-shaped rod 1 connecting the left and right sides of the expansion frame 2 to form an overall support structure to prevent the expansion frame 2 from shifting, the left and right sides of the rear end of the arc-shaped rod 1 are fixedly connected to the expansion frame 2, and the expansion frame 2 is designed to fit the oral cavity.

[0025] It also includes: a through hole 3 is provided inside the right side of the arc-shaped rod 1. The through hole 3 is designed to facilitate the sliding of the adjusting rope 4. The adjusting rope 4 is fixedly connected to the outside of the arc-shaped rod 1. The adjusting rope 4 is designed to pull one end of the arc-shaped rod 1 to adjust the distance between the two expanding frames 2. The outside of the adjusting rope 4 is slidably connected inside the through hole 3. A sliding column 6 is slidably connected inside the right side of the arc-shaped rod 1. The sliding column 6 is used to fix the adjusting rope 4. An installation groove 7 is provided inside the sliding column 6. The installation groove 7 is designed to facilitate the installation of the elastic metal sheet 8 and the rubber pad 9. An elastic metal sheet 8 is provided inside the installation groove 7. The elastic metal sheet 8 is designed to push the sliding column 6, thereby driving the sliding column 6 and the rubber pad 9 to squeeze the adjusting rope 4. The elastic metal sheet 8 is fixedly connected to the outside of the arc-shaped rod 1.

[0026] A rubber pad 9 is fixedly connected inside the sliding column 6. The rubber pad 9 is in contact with the outside of the adjusting rope 4. Under the push of the sliding column 6 and the elastic metal sheet 8, the rubber pad 9 squeezes the adjusting rope 4, thereby fixing the adjusting rope 4.

[0027] One end of the adjusting rope 4 is fixedly connected to a limiting ball 5. The limiting ball 5 is designed to limit the adjusting rope 4 and prevent the adjusting rope 4 from falling out of the mounting groove 7. The outer side of the adjusting rope 4 is slidably connected to the inside of the mounting groove 7.

[0028] The curved rod 1 is elastic, which drives the two arch expansion frames 2 to support the oral cavity. The elastic metal plate 8 is semi-circular in shape, and the semi-circular shape of the elastic metal plate 8 can better fit the curved rod 1.

[0029] A reinforcing metal plate 10 is fixedly connected to the outer side of the arc-shaped rod 1. The reinforcing metal plate 10 can enhance the elasticity of the arc-shaped rod 1. A second through hole 11 is opened inside the right side of the reinforcing metal plate 10. The design of the second through hole 11 is to facilitate the passage of the adjustment rope 4.

[0030] The outer side of the adjusting rope 4 is slidably connected to the inside of the second through hole 11. The second through hole 11 is aligned with the first through hole 3. The alignment of the second through hole 11 with the first through hole 3 allows the adjusting rope 4 to pass smoothly through the reinforcing metal plate 10 and the arc rod 1.

[0031] When using an orthodontic mouth opener, squeeze both sides of the curved bar 1 with your hand, then place the two expander frames 2 into the user's mouth. Release your grip on the curved bar 1; the two expander frames 2 will expand the user's mouth under the action of the repositioned curved bar 1. When the expansion is large and the user's mouth is small, press one side of the sliding post 6 to allow it to compress the elastic metal plate 8. This will cause the sliding post 6 to move the rubber pad 9 and stop compressing the adjusting rope 4. Then, pull the adjusting rope 4 to move both sides of the curved bar 1, adjusting the distance between the two expander frames 2. Release your grip on the mounting slot 7; the elastic metal plate 8 will reposition itself, and the repositioned mounting slot 7 will cause the rubber pad 9 to compress the adjusting rope 4, thus fixing the adjusting rope 4 and adjusting the distance between the two expander frames 2 to better fit the user's mouth.

[0032] By controlling the distance between the two expander frames 2, the expansion force and amplitude of the two expander frames 2 on the oral cavity can be adjusted, so that the expander frames 2 will not cause excessive muscle stretching in the user's oral cavity when expanding the oral cavity, thereby reducing postoperative oral muscle soreness and alleviating the user's discomfort.

[0033] Example 2

[0034] In this second embodiment, the other structures remain unchanged. The difference from the first embodiment is that the top of each of the two arch expanders 2 is fixedly connected to a drive post 12. The drive post 12 is designed to make it easier to press the two drive posts 12 on both sides so that the two arch expanders 2 no longer expand the oral cavity. The outer side of each of the two arch expanders 2 is attached with a peeling piece 13. The peeling piece 13 is designed to protect the contact surface with the oral cavity and improve hygiene.
