Abstract
The invention discloses an adjusting mechanism of a binocular magnifier. The adjusting mechanism comprises a hinged shaft, a first adjusting rod and a second adjusting rod; one end of the first adjusting rod and one end of the second adjusting rod are hinged to the hinged shaft, and a first magnifier and a second magnifier whose focuses are superposed are respectively fixed at the other ends; the focuses are disposed at the axis of the hinged shaft; and the distance between the center of the first magnifier and the axis of the hinged shaft is the same as the distance between the center of the second magnifier and the axis of the hinged shaft. The adjusting mechanism is designed according to features of a cone; the axial lead of the hinged shaft is the rotation center line of the cone; and the two magnifiers take the circumference at the bottom surface of the cone as a motion locus so as to adjust the linear distance between the two magnifiers for realizing interpupillary distance adjustment. It can be seen that the adjusting mechanism of the binocular magnifier solves the problem that a visual axis is always convergent with a fixed focus when the binocular magnifier is used for adjusting an interpupillary distance, and the adjustment is convenient. The invention also discloses an application method and a binocular magnifier.
