Outer circumference is equipped with the external screw thread for being connected with front cover；The dioptric piece is placed in the counterbore of pedestal, and dioptric piece is adopted
With the dedicated dioptric piece of individual of customization；The front cover capping on the base, and carries out dioptric piece by the cover board medial surface of front cover
It is fixed, the cover board center of front cover is equipped with the peep hole coaxial with pedestal observation bottom outlet, and the cover board lateral surface of front cover is indent
Arc surface, using the viewing surface as observation base.
Preferably, the counterbore is circular counter bore, and counterbore interior side is equipped with the spacing block set for preventing dioptric piece from rotating；
The dioptric piece is circular eyeglass, and the circumference side of dioptric piece cuts with notch corresponding with the spacing block set of counterbore.
Further, the dioptric piece needs can be used concave lens or presbyopic lens according to examiner.
Further, the cover board medial surface of the front cover is the arc surface being bonded with dioptric piece top surface so that front cover and bend
Mating plate realizes preferably fitting,
Further, it is additionally provided with the multi-turn burr concentric with peep hole on the cover board lateral surface of the front cover, to facilitate inspection
Survey person's eye water vapour distributes.
Further, the outer circumference of the front cover is equipped with anti-skid chequer, to facilitate hand to twist.
Compared with prior art, the utility model has following good effect:
The streak retinoscope of the utility model by by the observation base of window pipe front end be improved to by pedestal, dioptric piece and
The composite structure of front cover composition, when the examiner of wearing spectacles in observation base in use, can place matched
The dedicated dioptric piece of people, the examiner of such wearing spectacles can extract glasses, and the cap of skiascope is steadily fitted in forehead
On eyebrow, and from being carried out on the peep hole of observation base front cover, so that the examiner for effectively solving wearing spectacles is using band
The stable defect fast checked can not be carried out when shape light skiascope.Upon completion of the inspection, the examiner of wearing spectacles will observe
The dedicated dioptric piece of individual in seat takes out, this streak retinoscope is alternatively arranged as conventional streak retinoscope to be made for non-glasses wearer
With.
