Special-shaped retraction frame

The utility model belongs to the field of oral cavity mouth gags, and particularly relates to a special-shaped retraction frame which comprises an upper cross beam, a lower cross beam and side rods on the left side and the right side, the position of the upper cross beam is higher than that of the lower cross beam, correspondingly, each side rod is designed into an upper section, a middle transition section and a lower section from top to bottom, and arc transition is adopted between the middle transition section and the upper section and between the middle transition section and the lower section. The oral cavity mouth gag is unique in structural form, and can effectively and reasonably prevent the side traction hook assembly in the oral cavity mouth gag from making contact with the face in the oral cavity operation process, so that the side traction hook assembly is prevented from pressing the face in the operation process, and operation pain is reduced; the double-bent design of the side rods better fits t
