[0033] The working principle of the oral cavity expander is as follows:

[0034] In actual use, first, the adjusting cap 45 is loosened, the opening degree of the expander is reduced by pinching the two sides of the pinch piece 44 with fingers, then the expander is placed into the oral cavity of the patient, the two sides of the mouth opening piece 22 are attached to the corners of the mouth of the patient, then the pressure on the pinch piece 44 is gradually reduced, so that the first supporting arm 41 and the second supporting arm 42 drive the two sides of the mouth opening piece 22 to be opened outward under the elastic force of the supporting elastic piece 43, when the mouth opening piece 22 expands the oral cavity to an appropriate degree, the adjusting cap 45 is tightened to fix the two groups of supporting arms, so as to lock the opening degree of the expander. In the process, the upper and lower lip pieces 11 and the film piece 12 are attached to the upper and lower lips of the patient, the upper and lower lips of the patient are expanded by the lip piece 11 and the film piece 12, so as to provide a better treatment field for medical personnel. When the expander needs to be removed, the above operation steps are repeated in reverse.

[0035] Obviously, the above embodiments of the utility model are only examples for clearly illustrating the utility model, and are not a limitation on the embodiments of the utility model, and for ordinary skilled persons in the art, other different forms of changes or variations can be made on the basis of the above description, all the embodiments cannot be exhausted here, and any obvious changes or variations derived from the technical solutions of the utility model still fall within the protection scope of the utility model.
