Description

TECHNICAL FIELD

[0001] The utility model relates to telescope technical field especially is related to a binocular telescope eyepiece synchronous adjustment mechanism and telescope. BACKGROUND

[0002] A telescope is an optical instrument used for observing distant objects. It uses a combination of lenses or mirrors to magnify distant objects, allowing the observer to see a clearer image.

[0003] Telescopes are suitable for use in outdoor activities such as travel, bird watching, and watching sports events. A typical telescope consists of an objective lens and an eyepiece. The objective lens is a large lens at the front of the telescope that collects light from distant objects and focuses it into a real focal point. The eyepiece is a small lens close to the observer's eye that further magnifies the real focal point formed by the objective lens, creating a virtual image that is larger than the original object. To achieve a wider field of view, telescopes often have an adjustment mechanism between the eyepiece and the objective lens to adjust the focal length. However, in existing technology, the focal length adjustment mechanism uses VST, TMT or VISTA, which makes the adjustment mechanism of the telescope complex and increases the difficulty of maintenance and control.

[0004] Therefore, the technical personnel in the art are committed to developing a binocular telescope eyepiece synchronous adjustment mechanism and telescope that can accurately and quickly adjust the focal length of the eyepiece and is easy to operate. INVENTION CONTENTS
