Problems solved by technology

[0002] At present, the stretchable monocular observation mirror (telescope) on the market is widely liked by the public. Its structure is small and exquisite, and it is easy to use. It is necessary to extend the retractable lens barrel group to achieve focus adjustment to obtain clear image quality. This has a disadvantage, because the connection between the lens barrel and the lens barrel of the retractable lens barrel group is inconsistent, and the user's strength is also different. It is difficult to achieve precise focus when using

Abstract

The invention discloses an observation lens. The observation lens comprises a lens barrel, a telescopic lens fixing seat, a lens rotation ring and a rotation ring, wherein an inner side of the lens barrel is equipped with a first eyeglass, the rotation ring is internally equipped with a second eyeglass, the rotation ring is mounted in the telescopic lens fixing seat, the lens rotation ring is sleeved at an outer side of the telescopic lens fixing seat, the rotation ring can be driven through rotation of the lens rotation ring to move up and down in the telescopic lens fixing seat, and the telescopic lens fixing seat stretches into the lens barrel and is fixedly connected with the lens barrel. The observation lens is advantaged in that precise focusing can be realized.

Description

technical field [0001] The invention relates to the field of observation mirrors, more specifically, to an observation mirror. Background technique [0002] At present, the stretchable monocular observation mirror (telescope) on the market is widely liked by the public. Its structure is small and exquisite, and it is easy to use. It is necessary to extend the retractable lens barrel group to achieve focus adjustment to obtain clear image quality. This has a disadvantage, because the connection between the lens barrel and the lens barrel of the retractable lens barrel group is inconsistent, and the user's strength is also different. It is difficult to achieve precise focus when using it.
