[0002] In the medical industry, during the treatment and diagnosis of patients with oral diseases, it is necessary to understand and observe the basic conditions and causes of the oral cavity. Usually, a special oral mirror is used to observe the inside of the oral cavity, which is convenient for accurately and clearly observing the situation of the oral cavity, being able to timely discover problems and conduct treatment and diagnosis of oral diseases.

[0003] According to a Chinese patent document with the publication number CN218045054U, which discloses an oral mirror convenient for observation in stomatology, the stainless - steel handle is installed with a mirror frame through a connecting component and a bending piece. A reflector is adhesively fixed on the surface of the mirror frame. A light source is installed at the edge of one end of the mirror frame close to the bending piece. The light source includes an LED lamp bead and a button battery connected through a push - button switch. The connecting component includes a connecting sleeve welded and fixed at one end of the stainless - steel handle and a connecting baffle installed at one end of the connecting sleeve; the mirror frame connected to the stainless - steel handle through the connecting component and the bending piece is convenient for the disassembly and assembly between the stainless - steel handle and the bending piece through the connecting component, and is convenient for adjusting the angle between the stainless - steel handle and the mirror frame through the bending piece, facilitating the observation of tooth conditions through the adjusted reflector. At the same time, a light source is installed on the surface of the mirror frame, and the light source includes an LED lamp bead and a button battery connected through a push - button switch, so as to facilitate lighting the inside of the oral cavity through the light source.

[0004] Based on the retrieval of the above - mentioned patent and the combination with the existing oral mirrors, it is found that during the use of the above - mentioned oral mirror, the angle of the oral mirror can be adjusted through the cooperation between the stainless - steel folding handle and the bending piece, and the inside of the oral cavity can be illuminated with the cooperation of the light source. However, during the use, when observing the oral cavity, once the angle of the oral mirror is inappropriate, it needs to be taken out and bent and adjusted again. If not mastered well, it may need to be adjusted multiple times. If directly adjusted inside the oral cavity, it is easy to cause frictional damage to the oral cavity, making the oral cavity receive force and generate pain. Therefore, during the use, the angle of the oral mirror cannot be adjusted quickly and flexibly, resulting in a reduction in practicability. Summary of the Utility Model
