The inside of the support assembly 1 is made of stainless steel, and the outside is coated with medical rubber, which is convenient for cleaning and reduces the bad feeling when the patient comes into contact. The inflation assembly 3 is connected to an external gas source, and at the same time, the inflation assembly 3 can control the inflation and contraction of the airbag 5. The clamping assembly 6 can clamp or separate the support assembly 1 and the bearing assembly 2.
[0053] The bearing assembly 2 includes:

[0056] The specific implementation method is as follows: The bearing plate 21 is fixedly connected to the fixing plate 4, the driving plate 22 is rotatably connected to the bearing plate 21 through a connecting shaft, the driving plate 22 is L-shaped, when the airbag 5 expands and drives the bearing plate 21 to separate from the driving plate 22, the bearing plate 21 does not move, and the driving plate 22 moves upward, which can reduce the obstruction of the retractor to the outside of the oral cavity when the doctor is performing oral treatment.
[0057] The support assembly 1 includes:
[0058] A number of menisci 14, which are respectively rotatably installed in the arc-shaped grooves opened in the middle of one side of the driving plate 22 and the bearing plate 21, and a number of pits are arranged in a circumferential array on the outer side of the meniscus 14;

The meniscus 14 located on one side of the driving plate 22 is rotatably connected to the driving plate 22, and the meniscus 14 located on one side of the bearing plate 21 is rotatably connected to the bearing plate 21. There is a gap between the support plate 11 and the pressing plate 12 to facilitate the distinction between the support plate 11 and the pressing plate 12. The support plate 11 and the pressing plate 12 can independently rotate along the axis of the connected meniscus 14. Put the retractor into the patient's mouth, and the patient bites the support pad 13 with the teeth. The outer side of the support pad 13 is covered with rubber. The support plate 11 and the pressing plate 12 independently rotate along the axis of the meniscus 14 until it fits the position of the patient's teeth. Open the three-way control valve 31 until the inflation tube 33 is connected to the ventilation tube 32, and inflate the inflation tube 33. The airbag 5 expands, and the bearing plate 21 and the driving plate 22 rotate along the connecting shaft. The driving plate 22 rotates a certain angle, the patient's oral cavity is supported, the gingiva is inclined and deviated by a certain angle, the support pad 13 rotates along the axis of the rotating pin 131, follows the deviation of the patient's gingiva, and the upper surface of the support pad 13 always keeps in contact with the surface of the patient's teeth. The support pad 13 provides effective gingival support for the patient. When one side of the support assembly 1 blocks the doctor's treatment, open the three-way control valve 31 until the airbag 5 on the blocked side is connected to the inflation tube 33, and release the gas in the airbag 5. The support plate 11 and the pressing plate 12 approach each other to release space for the doctor's treatment.

[0071] A number of pull ropes 63, which are respectively fixedly installed at the other ends of the clamping pins 61.
[0072] The specific implementation method is: under the action of the elastic member 62, one end of the clamping pin 61 is clamped into the pit formed in the meniscus 14. The clamping pin 61 and the meniscus 14 can be separated through the pull rope 63, realizing the independent movement and locking of the support plate 11 and the pressing plate 12.
[0073] Working principle: When in use, the dilator is placed in the patient's mouth. The patient bites the support pad 13 with the teeth. The outside of the support pad 13 is covered with rubber. Under the action of the elastic member 62, one end of the clamping pin 61 is clamped into the pit formed in the meniscus 14. The clamping pin 61 and the meniscus 14 can be separated through the pull rope 63. The support plate 11 and the pressing plate 12 independently rotate along the axis of the meniscus 14 until they are adapted to the position of the patient's teeth. The three-way control valve 31 is opened so that the inflation tube 33 is communicated with the ventilation tube 32, and air is inflated into the inflation tube 33. The airbag 5 expands, and the bearing plate 21 and the driving plate 22 rotate along the connecting shaft. The driving plate 22 rotates by a certain angle, the patient's oral cavity is supported, the gingiva tilts and deviates by a certain angle, the support pad 13 rotates along the axis of the rotating pin 131, follows the deviation of the patient's gingiva, and the upper surface of the support pad 13 always keeps in contact with the surface of the patient's teeth. The support pad 13 provides effective gingival support for the patient. When one side of the support assembly 1 blocks the doctor's treatment, the three-way control valve 31 is opened so that the airbag 5 on the blocked side is communicated with the inflation tube 33, and the gas in the airbag 5 is released, and the support plate 11 and the pressing plate 12 approach each other.
