Specific implementation mode
Specific embodiment of the present invention is described in further detail below in conjunction with the accompanying drawings.
In the description of the present invention, unless otherwise indicated, term "upper", "lower", "left", "right", "front", "rear",
The orientation or state relation of the instructions such as " top ", " bottom " are orientation based on ... shown in the drawings or state relation, merely to just
It is described in description the utility model and simplifying, does not indicate or imply the indicated mechanism or certain party that component must have
Position, with specific azimuth configuration and operation, therefore should not be understood as limiting the present invention.
In the description of the present invention, it should be noted that unless otherwise clearly defined and limited, term " connection "
It shall be understood in a broad sense, for example, it may be being fixedly connected, may be a detachable connection, or be integrally connected；It can be direct phase
It even, can also be indirectly connected through an intermediary.For the ordinary skill in the art, on being understood with concrete condition
State the concrete meaning of term in the present invention.
A kind of ophthalmic optometry mirror, including frame 1 and two temples 2 for being separately mounted to 1 both ends of frame, the two of frame 1
End is provided with sliding sleeve 11, is connected with to 11 inner slidable of sliding sleeve a sliding block 3, on madial wall of the sliding sleeve 11 far from 1 one end of frame
It is provided with annular groove 12, rubber ring 4 is embedded in annular groove 12, threaded one end connection of the sliding sleeve 11 far from frame 1 is useful
In the end cap 5 for compressing rubber ring 4, threaded one end of the sliding block 3 far from frame 1 is connected with connecting rod 6, the one end of connecting rod 6 far from sliding block 3
Activity stretches out in outside end cap 5 after rubber ring 4 and end cap 5 and is provided with the bending 61 towards 2 side of temple, temple 2 and folding
