Claims

[Scope of utility model registration request]

The pivot shaft for inserting and connecting the pivot bearing pieces of the left and right binocular bodies consists of a cylinder shaft, and is formed with a vertically elongated hole drilled through the center in the length direction, and the center into which the connecting rod of the eyepiece barrel is inserted. The shaft is inserted into the inner cylinder of the pivot shaft so as to be slidable up and down, and the control pin is fixedly installed at the lower end of the center shaft so as to protrude from the vertically elongated hole of the pivot shaft. The lever is rotatably installed at one end of a cylindrical shaft, and the lever main body is inserted into the outer cylinder of the pivot at the cylindrical shaft, and the lever is rotatably installed at one end of a cylinder shaft. The machine room is surrounded by a horizontal floor part and side walls, and a long hole is bored in the floor part to overlap and pass through the vertical hole of the pivot, so that the tip of the control pin protrudes above the floor surface and is controlled. A slider is installed that engages the pin and slides back and forth along the elongated hole, the slider is meshed and connected to the lever via a plurality of gears, and a cover is installed on the upper surface of the machine room. The cover has elongated holes formed therethrough corresponding to the positions to which the slider moves, and a focal length display scale is attached to the surface thereof, and an indicator pin is installed vertically on the upper surface of the slider to indicate the movement of the slider. A focus adjustment device for binoculars constructed by having the tip slightly protrude from the elongated hole in the cover.
