Abstract: A rotating shaft with radial press device comprises a cylindrical rod and at least a friction part. The cylindrical rod extends from the rotating shaft and provides at least a milled face. The friction part is a ring piece composed of a circular section and an arched section and a gap is formed between the circular section and the arched section. An axial hole is surrounded by both of the circular section and the arched section for accommodating the cylindrical rod. Further, the arched section has a gradually reduced inner radius. As soon as the cylindrical rod is tightly pressed by the arched section, a position of standstill can be formed and when the milled face touches the free end of the arched section, the cylindrical rod can moves in a direction so that the milled face keeps contact with the free end of the arched section in a state of locking automatically.

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.

Abstract: A support base of a liquid crystal display includes a stationary part, a rotational part, an axial joint part and a catch device. A resilient device can be selectively joined to the support base. A lock jut can selectively move in a rotary recess for angular adjustment or engage with lock recess to make the liquid crystal display being parallel to the lower base during the rotational part rotating with the locating plate.
