Glasses for auxiliary maintenance of precision instrument

Abstract

The invention discloses glasses for auxiliary maintenance of a precision instrument. The glasses include a nose pad assembly, glasses frame brackets are symmetrically arranged at the two ends of the nose pad assembly, wherein the glasses frame brackets and the nose pad assembly are fixedly connected in an inserting manner; fastening locking pieces are symmetrically arranged on the side faces of the nose pad assembly and fixedly connected with the nose pad assembly in a threaded fit mode, a magnifying lens cone is arranged on the upper end face of each glasses frame bracket, the magnifying lenscone is movably connected with the glasses frame bracket in an inserted mode, and a glasses claw limiting piece is arranged at one end of the glasses frame bracket. The nose pad assembly and the glasses frame brackets are matched with each other, people with different head forms can wear the glasses suitably, meanwhile, glasses claws and the glasses claw limiting pieces are matched with each other, people with different head forms can wear the glasses comfortably and firmly, a user can see finer parts clearly through the arranged the magnifying lens cones, and therefore the precision instrument can be maintained conveniently.

Description

technical field [0001] The invention relates to the technical field of spectacles, in particular to spectacles used for auxiliary maintenance of precision instruments.
