As a preferred solution, the end fixing sleeve that the first level shaft is located at chassis outer side, which is equipped with, to be adjusted
Disk；The end fixing sleeve that second horizontal rotating shaft is located at chassis outer side is equipped with adjustment disk.
The beneficial effects of the invention are as follows：This eyepiece parfocalization mechanism structure is simple, easy to use and manufacturing cost is low.
Due to being equipped with annular step surface in pedestal, annular step surface is equipped with magnetic absorption ring, magnetic absorption ring upper surface
For eyepiece positioning surface, it is equipped with first level shaft on pedestal, is arranged on the part that first level shaft is located in pedestal
One eccentric wheel is equipped with positioning seat in pedestal, and positioning seat upper surface is equipped with reflective mirror, and trunnion axis rotation is lower than eccentric wheel top surface
So as to the placement of eyepiece, trunnion axis, which rotates, makes eccentric wheel top surface be higher than magnetic absorption ring upper surface to incite somebody to action for magnetic absorption ring upper surface
Eyepiece ejection avoids the eyepiece adjusted from rotating without applying more energetically to eyepiece, it is ensured that and 0 label is accurate, into
And guarantee the installation accuracy of subsequent diopter adjustment circle.
Since base upper surface is equipped with elastic washer, impact when eyepiece is installed between pedestal can be slowed down, to protect mesh
Mirror.
Due to being equipped with second horizontal rotating shaft coaxial with first level shaft on pedestal, the second horizontal rotating shaft is located at pedestal
It is arranged with the second eccentric wheel on interior part, eyepiece can be made more easy when removing.
Since the end fixing sleeve that first level shaft is located at chassis outer side is equipped with adjustment disk, in order to first level shaft
Rotation；The end fixing sleeve that second horizontal rotating shaft is located at chassis outer side is equipped with adjustment disk, in order to the second horizontal rotating shaft
Rotation.
