[0018] Compared with the prior art, the utility model has the following beneficial effects: the oral mirror that is easy to adjust the mirror angle:

[0019] 1. The adjustment mechanism facilitates the angle adjustment of the observation mirror. When the observation mirror is placed in a person's mouth, due to light or a person's standing position, the traditional oral mirror cannot conveniently change the angle of the observation mirror in the original state. Hold the handle with your hand, and then put the observation mirror into the mouth of the person to be observed. When the angle of the observation mirror needs to be changed, use your thumb to turn the blade-shaped protrusion of the rotating handle 1 to rotate the rotating handle 1, and the meshing gear 2 fixed on the upper end surface of the rotating handle 1 rotates at the same time, and the meshing wheel 1 meshing with the meshing gear 2 rotates at the same time, and the rotating shaft 2 fixedly connected to the side surface of the meshing wheel 1 rotates at the center of the rotating base 1. During the rotation of the rotating shaft 2, the rotating shaft 1 is driven to rotate on the rotating base 2 through the transmission belt at the same time. During the rotation of the rotating shaft 2, the rotating shaft 1 drives the observation mirror to be active through the connecting rod, so that during the observation process, the Z-axis rotation of the observation mirror can be achieved with one hand.

[0020] 2. The rotating mechanism further facilitates observation. During the observation process, the Z-axis rotation of the observation mirror can cope with most situations. However, due to the holding posture, it is difficult to hold the wrist for a long time in certain postures, which will cause wrist pain. The mechanism drives the rotating shaft 3 on one side of the outer shell to rotate on the bearing by rotating the rotating handle 1 with the thumb. The outer shell rotates at the same time, and the observation mirror rotates at the same time, thereby realizing the X-axis rotation of the observation mirror. In cooperation with the adjustment mechanism, oral observation can be performed while ensuring a comfortable posture. BRIEF DESCRIPTION OF THE DRAWINGS

When the observation mirror 5 is placed in the oral cavity of a person, due to the light or the standing position of the person, the traditional oral mirror cannot conveniently realize the angle change of the observation mirror 5 in the original state. Hold the handle 2 with your hand, and then put the observation mirror 5 into the oral cavity of the person to be observed. When the angle of the observation mirror 5 needs to be changed, use your thumb to turn the leaf-shaped protrusions of the rotating handle 24. The protrusion causes the rotating handle 24 to rotate, and the meshing gear 214 fixed on the upper end surface of the rotating handle 24 rotates at the same time, and the meshing wheel 13 meshing with the meshing gear 214 rotates in the dustproof shell 7 at the same time, and the rotating shaft 212 fixedly connected to the side surface of the meshing wheel 13 rotates at the center of the rotating base 16.
