Detailed Description

The utility model is further described with reference to the following figures and specific examples.

Referring to fig. 1, the device mainly comprises a segmental spring ring 1, a rotatable opening rod 2, a rubber strip buckle 3, a metal ring 4 and a support rod 5. In this embodiment, the spring ring 1 is composed of four springs 1.1 and four metal bars 1.2. Wherein the spring 1.1 and the metal bar 1.2 are alternately arranged, and the spring 1.1 is a compression spring which can expand towards two sides to support the inner segmental spring ring 1. Four metal bars 1.2 in the segmental spring ring 1 are respectively connected with four support rods 5, the top ends of the four support rods 5 are connected to a metal ring 4 outside the opening, and the tops of the support rods 5 are bent from inside to outside and connected to the inner side of the metal ring 4. And the support rod 5 and the segmented spring ring 1 have certain deformation capacity. The bottom ends of the rotatable opening rods 2 are hinged to the metal bar 1.2 and can rotate around the metal bar 1.2, and the plurality of opening rods 2 rotate outwards simultaneously to open oral mucosa. Wherein the metal bar 1.2 is located the part of buccal cavity both sides and sets up longer, can be relatively intact laminating oral cavity inner structure, prevents falling of operation in-process device.

Referring to fig. 2-4, the appearance of the device mainly comprises a segmented spring ring 1, a rubber strip buckle 3, a metal ring 4, a support rod 5 and a rubber ring 6.
