The general way of use is that the doctor holds the oral mirror and inserts it into the patient's mouth. The emergence of the oral mirror has brought a new model for oral examination and treatment. When the patient's lesions are displayed in front of the patient, no more description or professional knowledge is needed.

[0003] Chinese patent publication number CN219461096U, publication time 20230804 discloses an oral medical oral mirror, including a lens, two connecting ears are fixedly installed on the side wall of the lens, a connecting shaft is fixedly installed between the two connecting ears, a rotating sleeve on the surface of the connecting shaft is provided with a fixed shaft, a sliding rod is fixedly installed on the surface of the fixed shaft, a sliding sleeve is provided on the surface of the sliding rod, a limiting mechanism for limiting the sliding sleeve is provided on the surface of the sliding rod, and a driving mechanism for driving the lens to rotate around the connecting shaft is provided inside the sliding rod.

[0004] For example, the above-mentioned existing dental mirror can adjust the overall length of the dental mirror through a sliding rod and a sliding sleeve that are slidably connected and a press-type fixing mechanism. In the specific implementation process, the operator needs to cooperate with both hands to complete the overall length adjustment of the dental mirror. During the oral examination process, it is inconvenient for the operator to free up both hands to adjust the dental mirror at the same time. Therefore, it is urgent to propose a corresponding combined dental mirror to solve the above problems. Utility Model Content

The operator can complete the operation with one hand, thereby improving the convenience of using the oral mirror. The angle wheel 6 is turned by fingers, and the angle wheel 6 drives the driving wheel 12 to rotate through the rotating rod 11. The driving wheel 12 drives the shaft rod 11 to rotate by engaging with the driven wheel 13. The ear seat 2 drives the lens 1 to deflect around the shaft rod 14 as the axis until the lens 1 deflects to a suitable angle and stops pushing the angle wheel 6. At this time, the damping bearing ensures the relative stability of the rotating rod 11, and the self-locking of the driving wheel 12 and the driven wheel 13 ensures the stable position of the lens 1, so that the angle of the lens 1 can be adjusted by the operator with one hand.
