Specific embodiment
Embodiment involved in the utility model is described in further details with reference to the accompanying drawing.
A kind of sight tester combined with Figure 1 and Figure 2, including eyepiece stalk 2, rotating cylinder 3 and objective tube 5 are set in eyepiece stalk 2
There are an ocular lens 21, object lens piece 51 is equipped in objective tube 5, is equipped with the first plane mirror 31 and the second plane mirror 32 in rotating cylinder 3, first
Plane mirror 31 is set to 2 side of eyepiece stalk, and the second plane mirror 32 is set to 5 side of objective tube, the lower end of eyepiece stalk 2 and the upper end of rotating cylinder 3
It is rotatably connected by screw thread, the upper end of objective tube 5 and the lower end of rotating cylinder 3 are rotatably connected also by screw thread.
First plane mirror 31 is with screw thread clockwise movement, and the second plane mirror 32 is with screw thread counterclockwise movement, i.e. the first plane
Mirror 31 and the second plane mirror 32 opposite or reverse motions always.
3 surface of rotating cylinder is equipped with calibration loop 4, and the scale of calibration loop 4 is standard vision value.
The upper end of eyepiece stalk 2 is equipped with eyepiece gum cover 1, and eyepiece gum cover 1 is for protecting ocular lens 21 not contacted by human skin
It is polluted.
The lower end of objective tube 5 is equipped with protection gum cover 6, and gum cover 6 is protected to be used for the protection eyeglass not screen with mobile terminal 8
Directly contact.The two sides of protection 6 upper surface of gum cover are symmetrically arranged with hook.
Ocular lens 21 and object lens piece 51 are convex lens.
It further include fixture 7, fixture 7 is removably connect by hook with protection gum cover 6.Fixture 7 is used to fixed mobile whole
End 8, makes the screen center of mobile terminal 8 face object lens piece 51.
Wireless communication module is additionally provided with inside objective tube 5, wireless communication module includes microprocessor, memory, wireless hair
Emitter and power supply.Memory is rotated for storing binary code corresponding to standard vision value, microprocessor according to calibration loop 4
Current standards eyesight value corresponding later reads corresponding binary code from memory, wireless transmitter be used for by this two
