ABSTRACT:
In a pair of binoculars, the left and right control pieces are connected to a bridge on the body of the binoculars by means of a securing mechanism so that when one of these pieces is pushed down, the corresponding piece is automatically depressed.
The slanted opening of the control piece and the bridges guide opening are connected. Also a connecting pole for the control pieces and the rod which enables the ascent and descent, is fixed, and because of this connecting rod the eyepiece lenses can be extended or retracted smoothly.
