Abstract

An open/close mechanism for the base axis of two-axis binocular telescope, which can change the gap between the left and right lens barrel and still maintains the parallel status of their optical axis, have the following features: 1. base plate allocated between the left and right lens barrel for supporting the free rotation of left and right lens barrel; 2. four supporting parts located on two surfaces parallel with the optical axis of the base plate; 3. concave parts formed on the supporting part with the proper flexibility by the supporting length for supporting the lens barrel.
