Problems solved by technology

[0004] The purpose of the present invention is to provide a pediatric oral retractor, aiming at solving many disadvantages of oral retractors in the prior art, such as that the retraction strength cannot be adjusted, or only for the upper and lower teeth, and the lips cannot The effect of stretching will affect the operating space of medical staff, or only the lips can be stretched, requiring children to open their mouths with extra force, and jaw soreness will also occur for a long time, and most of the existing stretchers occupy a lot of space in children's mouths. Many, greatly reducing the operating space for medical staff and other issues
