[0006] Preferably, the upper end of the adjusting seat is formed by stamping to create a fastening groove, and the fastening groove is snapped and fastened to the protective cover.

[0007] Preferably, the width of the protective cover is half the width of the fastening groove, and the thickness of the protective cover is the same as the depth of the fastening groove.

[0008] Preferably, the connecting rods at corresponding positions on both sides of the movable plug rod are provided with grooves for movable insertion into the movable plug rod.

[0009] Preferably, the protective cover has a convex-shaped structure.

[0010] Preferably, the adjusting seat has grooves on the opposite side of the end near the movable plug rod that engage with the protrusion of the protective cover.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: The adjustable orthodontic appliance has a protective cover on the adjustment seat, which can cover the adjustment hole of the spiral expander, effectively reducing the problem of dirt entering the adjustment hole and making cleaning difficult. The adjustable orthodontic appliance has a movable connecting rod fixed to one side of the protective cover, and the movable connecting rod is locked between two connecting rods on one side, ensuring that the protective cover can be rotated open and that the connecting rods on both sides can move relative to each other for tightening and adjustment of the orthodontic appliance.

[0018] 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.

[0019] Please see Figure 1-5This utility model provides a technical solution: an adjustable oral appliance, comprising an oral appliance body 1, with symmetrically arranged adjustment seats 3 on the oral appliance body 1, and a spiral expander 5 installed in each adjustment seat 3. The spiral expander 5 has an adjustment hole 501 in its center. Connecting rods 2 are fixed to the front and rear sides of the adjustment seats 3 respectively, and a protective cover 6 is provided at the upper center of each adjustment seat 3. The protective cover 6 has a convex shape, which allows for easy opening and closing of the protective cover 6, thereby achieving adjustment. The protective treatment at the middle of the adjustment seat 3 prevents solid food residue from entering the adjustment hole 501, allowing the protective cover 6 to shield the adjustment hole 501. A fastening groove 301 is formed at the upper end of the adjustment seat 3 by stamping, and the fastening groove 301 is snapped into place with the protective cover 6. This structure integrally forms the fastening groove 301 on the adjustment seat 3. While positioning the protective cover 6 through the fastening groove 301, it prevents the protective cover 6 from protruding and affecting oral comfort. The width of the protective cover 6 is half the width of the fastening groove 301. The thickness of the cover 6 is consistent with the depth of the fastening groove 301. This structure can cover the area of ​​the adjustment hole 501 through the protective cover 6 to prevent solid residue from entering the adjustment hole 501 and making it difficult to clean. The fastening groove 301 plays a role in fastening and locking the protective cover 6 to ensure that the protective cover 6 is tightly closed. When it is necessary to tighten and adjust the spiral expander 5, the protective cover 6 can be pried open with a tool. One end of the protective cover 6 is inserted into the fixed movable plug rod 4, and the movable plug rod 4 corresponds to the position of one of the connecting rods 2 on one side. The connecting rods 2 at corresponding positions on both sides are provided with grooves for movably engaging with the movable plug rod 4. This structure allows the movable plug rod 4 to be rotated and positioned via the connecting rods 2. At the same time, when the adjusting seat 3 is tightened by the spiral expander 5, the connecting rod 2 can move relative to the movable plug rod 4. The side of the adjusting seat 3 near the end of the movable plug rod 4 is provided with grooves that engage with the protrusions of the protective cover 6. This structure allows the adjusting seat 3 to move without being obstructed by the protective cover 6 when it is tightened.

[0020] Working principle: When using this adjustable orthodontic appliance, the main body 1 of the appliance is first fixed to the patient's teeth via the connecting rod 2. The two adjustment seats 3 are respectively fixed to the connecting rod 2 on the same side. The adjustment seats 3 are connected and fixed by the spiral expander 5. When adjusting the main body 1 of the appliance, pry open the protective cover 6, and then adjust the tightening through the adjustment hole 501 in the middle of the spiral expander 5. The movable plug rod 4 moves relative to the connecting rod 2 to avoid affecting the tightening process. In daily life, the protective cover 6 is positioned on the adjustment seat 3 through the fastening groove 301 to cover the adjustment hole 501, so as to prevent solid food residue from entering the adjustment hole 501 and making it inconvenient to clean. This completes a series of operations.

[0021] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
