Abstract
A rotating shaft with open and shut function comprises a shaft part, a fixing part, a slide part, an extension part and/or a rotating part. When a lid on an article rotates, the rotating slants of the rotating projections on the rotating part move along the end projections of the slide part to allow the sliding juts on the slide part moving along the fixing juts on the fixing part so as to compress the extension part between the fixing part and the slide part. When the lid rotates an angle till the rotating projections contacting face to face with the end projections, the lid can be located in a state of standstill. When rotating slants move to the slant side of the respective end projection at the another side thereof, the extension part stretches to allow the slide part moving back axially so that the rotating slants can move along the end slants to form a state of engagement between the rotating slants and the end slants respectively and the lid can be fully opened automatically.
