The two mounting plates 10 are arranged opposite to each other, and the two mounting plates 10 are provided with a slide groove 11; the multiple groups of fixing parts 20 are slidably installed in the two slide grooves 11, and each group of fixing parts 20 is two fixing parts 20 arranged opposite to each other, corresponding to the two mounting plates 10 one by one, and the fixing parts 20 have a receiving space 21 for abutting against the teeth; the multiple fixing components 30 are installed between the two fixing components 30 arranged opposite to each other in each group of fixing components 30.

[0030] In this embodiment, if Figure 1As shown, the plurality of sets of fixing members 20 include at least two sets of fixing members 20, and the mounting plate 10 is divided into two layers, each set of fixing members 20 is slidably mounted on the two layers of mounting plates 10, and the receiving spaces 21 on the fixing members 20 are respectively located on the two layers of mounting plates 10 and facing the teeth to be fixed, so as to accommodate and abut against the teeth. Figure 2 As shown, the mounting plate 10 has a certain curvature to correspond to the curvature of the tooth distribution and improve the stability of the installation. A plurality of fixing components 30 are respectively installed between two fixing members 20 of each group of fixing members 20. Correspondingly, there are at least two fixing components 30, which are inserted into the slide groove 11, connected to the fixing members 20 installed on the upper and lower mounting plates 10, and can fix the relative position between the fixing members 20 and the mounting plate 10.

[0031] Further, in some implementations of this embodiment, Figures 3 to 5 As shown, the fixing member 20 includes: a fixing plate 22 and a connecting block 23. The fixing plate 22 has a receiving space 21 thereon; the connecting block 23 is mounted on the fixing plate 22, and the connecting block 23 is slidably mounted in the slide groove 11.

[0032] In this embodiment, if Figure 3 As shown, the accommodation space 21 is formed by a fixing plate 22 and contacts the teeth. Medical rubber can be used to improve the comfort and fit of the contact. The fixing plate 22 is fixedly mounted on the connecting block 23, specifically, it is fixed by bonding. The connecting block 23 contacts the mounting plate 10 and is partially inserted into the slide groove 11 to support the fixing plate 22.

[0033] Further, in some implementations of this embodiment, Figures 1 to 4 As shown, the mounting plate 10 includes two guide blocks 12. Two guide grooves corresponding to the two guide blocks 12 are formed on the connecting block 23.

[0037] Further, in some implementations of this embodiment, Figure 3 and Figure 5 As shown, further, the fixing assembly 30 also includes: a sleeve 31, a first locking member 32, and a second locking member 33. The sleeve 31 is rotatably mounted on the second mounting column 25, and is sleeved on the first mounting column 24, and is threadedly connected to the first mounting column 24. The sleeve 31 is rotated to drive the first mounting column 24 to slide relative to the slide groove 11; the first locking member 32 is rotatably mounted on the first mounting column 24, and the first locking member 32 is rotated to drive the first locking member 32 to move along the axis toward the connecting block 23 on which the first mounting column 24 is installed, so as to abut against the inner wall of the slide groove 11, thereby fixing the relative position of the connecting block 23 and the fixing plate 22; the second locking member 33 is rotatably mounted on the second mounting column 25, and the second locking member 33 is rotated to drive the second locking member 33 to move along the axis toward the connecting block 23 on which the second mounting column 25 is installed, so as to abut against the inner wall of the slide groove 11, thereby fixing the relative position of the connecting block 23 and the fixing plate 22.

[0038] In this embodiment, if Figure 5 As shown, the second locking member 33 is rotatably covered on the second mounting column 25, and the second locking member 33 is abutted against the slide grooves 11 on both sides to lock the connecting block 23 and the mounting plate 10, thereby fixing the mounting position of the fixing plate 22 and the teeth, as shown in FIG. Figure 3 As shown, the first locking member 32 is rotatably covered on the first mounting column 24 to abut against the two side surfaces of the slide groove 11 to fix the relative position between the other upper connecting block 23 and the mounting plate 10, thereby fixing the contact position between the upper and lower fixing plates 22 and the teeth to prevent slippage and improve the reliability and stability of the installation.

[0039] Further, in some implementations of this embodiment, Figure 3 As shown, the contact surfaces of the first locking member 32 and the second locking member 33 with the slide groove 11 are both inclined surfaces, and the first locking member 32 and the first mounting column 24 are threadedly matched, and the second locking member 33 and the second mounting column 25 are also threadedly matched.

[0040] In this embodiment, if Figure 3 As shown, the first locking member 32 and the second locking member 33 are provided with internal threads, and the upper parts of the first mounting column 24 and the second mounting column 25 are provided with external threads. By rotating the first locking member 32 and the second locking member 33, the inclined surfaces on the first locking member 32 and the second locking member 33 are driven to move toward the direction close to the inner wall of the slide groove 11 to abut against the inner wall of the slide groove 11, thereby fixing the positions of the first mounting column 24 and the second mounting column 25 in the slide groove 11 to limit the sliding of the fixed plate 22.

[0041] Further, in some implementations of this embodiment, Figures 1 to 4 As shown, the fixing plate 22 is a U-shaped plate.

[0042] In this embodiment, if Figure 3 As shown, the cross-section of the fixing plate 22 is U-shaped to accommodate the teeth to be fixed. The curved surface size of the U-shaped plate has multiple sizes to adapt to the types of teeth in different situations and improve applicability. By adding fillers in the U-shaped plate, the contact surface between the U-shaped plate and the teeth is increased, thereby improving the reliability and stability of fixation.

[0043] To sum up, when using a child's mouth opener that is easy to observe, the connecting block 23 installed in the slide groove 11 is slidably mounted to adjust the position of the fixing member 20 on the mounting plate 10, and then the fixing position of the fixing plate 22 and the teeth is adjusted to a position that is easy to observe, and then the sleeve 31 is rotated to adjust the height of the upper and lower mounting plates 10, and then the angle of the opening is adjusted, and the first mounting column 24 and the second mounting column 25 are rotated to lock the relative position between the upper and lower fixing plates 22 and the mounting plate 10. Through threaded fitting installation and moving abutment locking of the inclined surface, the stability and reliability of the fixation are improved, the tedious process of repeatedly replacing the inclined wedge pad during installation is reduced, and the installation efficiency is improved. The fixing plate 22 and the connecting block 23 are slidably mounted on the slide groove 11 of the mounting plate 10 to facilitate the adjustment of the installation position of the fixing component 30, reduce the obstruction of medical staff's observation, improve the use efficiency, and thus improve convenience.

[0044] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can easily think of changes or substitutions within the technical scope recorded in the utility model, which should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
