[0002] Ophthalmic optical biometers are suitable for hospital ophthalmology departments to measure visual acuity or the axial length, corneal curvature and anterior chamber depth of patients' eyes, as well as the diameter of the human cornea and calculate the degree of the artificial lens to be implanted in the eye. In optical measuring instruments, the reflector is an important component, which is mainly used to reflect light so that the measuring instrument can accurately measure and analyze the object being measured.

[0003] In optical measurement, the reflection angle of the reflector needs to be adjusted at any time, so an adjustment mechanism of the reflector is needed. During use, the existing adjustment mechanism usually rotates the reflector through a shaft to achieve the effect of adjusting the reflection angle. The reflector will be offset when it is hit, resulting in a change in the angle of the reflected light. The reflection angle needs to be readjusted. The angle adjustment process is not only cumbersome, but the adjustment accuracy cannot be guaranteed, which will affect the accuracy of biological measurement.
