Description

Structure of telescopic bus

Technical Field

The utility model relates to a time table technical field, concretely relates to structure of telescopic ba.

Background

The watch is also called a wristwatch. I.e. a tool to be worn on the wrist for timing purposes. In social situations, wearing a watch usually means that the time concept is strong and the wind is rigorous; people who do not wear watches or who frequently ask others for time always have a lot of thoughts, which often indicates that the time concept is not strong. In a regular social occasion, the watch is often seen as jewelry, and is particularly valued for men who only wear a ring jewelry at ordinary times. One has even emphasized that: the watch is not only jewelry of men, but also the most important jewelry of men. In western countries, watches, pens and lighters were once called "three-piece treasure" for adult men, which is a matter of principle for every man. Like jewelry, watches worn by people in social situations often show their status, identity and wealth.

The bar is one of essential accessories of the watch, and is connected with the clock mechanism through a handle shaft to realize the winding of the clock mechanism, the time correction and adjustment and the week calendar correction and adjustment.
