A method for assembling a ball valve using a system having a support structure and a tool includes positioning a body of the ball valve on a surface of the support structure. The method also includes driving one or more engaging members of the tool radially outward from a retracted position to an expanded position to engage a seat disposed within the body of the ball valve. The method further includes adjusting an axial position of the surface of the support structure relative to the one or more engaging members of the tool while the seat is engaged by the one or more engaging members of the tool to drive the seat into a seated position within the body of the ball valve.

A holding tool for fixing bearings contains: a fixer, a rotary bar, and a plurality of positioning paws. The fixer includes a threaded hole and plural slots, one end of an inner wall of each slot communicates with the threaded hole, and each positioning paw is mounted on each slot. The fixer also includes a plurality of springs, each being fixed on each slot and each positioning paw has a stepped abutting rib and a tilted guiding face. The rotary bar includes a screwing section for screwing with the threaded hole, and the rotary bar also includes a conical contacting segment formed on a first end thereof and inserting through the threaded hole, wherein the contacting segment abuts against the tilted guiding face, after the rotary bar is screwed, such that each positioning paw is pushed by the contacting segment to expand outwardly.

Improved methods and apparatus for supporting a tumbler, bottle, or similar items are disclosed. The apparatus includes a handle portion with a point of insertion for a control mechanism, and a stem portion extending from the handle. The stem portion comprises an upper stem portion with a tapered bottom surface and a lower stem portion featuring an off-set wedge that tilts to engage an interior surface of the tumbler. The control mechanism, which may include a threaded screw, spring-actuated lever, or cam system, interacts with one or more nuts positioned in the handle and off-set wedge to achieve precise tilting motion. Additional embodiments include flexible arms, expandable bladders, and butterfly-type mechanisms for gripping various drinkware items. The apparatus is suitable for applications such as engraving, painting, or aesthetic displays, providing secure engagement, adaptability, and protection of fragile surfaces during use.
