Further, the first measuring plate 1 comprises an intraoral portion 2 for the patient to bite and an extraoral portion extending out of the patient's mouth, and the extraoral portion comprises a connecting portion 3 and an indicating wing 4 arranged at both ends of the connecting portion 3. A first sliding matching structure 5 is arranged between the indicating wing 4 and the connecting portion 3, thereby realizing the sliding connection between the indicating wing 4 and the connecting portion 3, so that the indicating wing 4 can slide in a direction close to or away from the connecting portion 3.

[0040] Reference Figure 1 and Figure 2The first sliding matching structure 5 includes a first slideway 501 provided at the end of the indicating wing 4 and a first plug-in block 502 fixedly provided at the end of the connecting portion 3, and the first plug-in block 502 is slidingly matched with the first slideway 501. A first mounting groove 503 is also provided on the surface of the first plug-in block 502, and a first clamping block 504 is provided in the first mounting groove 503. The first clamping block 504 can move in the direction of entering or moving away from the first mounting groove 503. A first return spring 505 is provided at the bottom of the first mounting groove 503, and the two ends of the first return spring 505 are respectively abutted against the bottom of the first mounting groove 503 and the side wall of the first clamping block 504. When the first return spring 505 is in a natural state, a part of the first clamping block 504 protrudes out of the first mounting groove 503. A plurality of first clamping holes 506 are also provided on the surface of the indicating wing 4, and the plurality of first clamping holes 506 are evenly spaced and distributed along the opening direction of the first slideway 501, and are connected to the first slideway 501. When the first plug block 502 is plugged into the first slideway 501, the first clamping block 504 can extend from the first clamping hole 506, so that the indicating wing 4 is fixed to the connecting part 3. With such a configuration, in actual use, the width of the first measuring plate 1 can be adjusted according to the patient's facial shape to improve the adaptability of the device. It is worth noting that when the width of the first measuring plate 1 is adjusted, the adjustment distances of the first sliding matching structures 5 on both sides should be symmetrical, so that the moving distances of the two indicating wings 4 relative to the connecting part 3 are the same, avoiding the situation that the lengths on both sides do not correspond and affect the use. When the width needs to be adjusted, the operator presses the first clamping block 504, and then pulls the indicating wing 4 to adjust. When a certain distance is adjusted (adjusted from a first clamping hole 506 to another adjacent first clamping hole 506), under the action of the first reset spring 505, the first clamping block 504 automatically pops out from the first mounting slot 503 and extends from the first clamping hole 506, so that the indicating wing 4 is fixed to the connecting part 3. Furthermore, for ease of operation, the first clamping block 504 is configured as a spherical block.
