Abstract
An open ended cylindrical chuck device has an inner fixing ring, an outer movable turning ring, and three movable screw threaded bars crossing the chuck device. While the turning ring is turned, the screw threads on the turning ring move three screw threaded bars to hold a bottle to be locked. A fixing pin crosses two holes which located separately on fixing ring and turning ring to stop their movement. A cylindrical cap with a regular lock locks the chuck device. Thus the bottle is locked.

A locking device comprising:
- an open ended, hollow, cylindrical holding means having an open ended, hollow, cylindrical inner fixing ring, an open ended, hollow, cylindrical outer movable turning ring, and three or more threaded bars, said fixing ring having a group of open ended holes on its top surface, said movable turning ring having a group of longitudinal ditches on its top surface and having a number of threads on its bottom surface, said movable turning ring being hooped onto said fixing ring to thereby rotate around said fixing ring, said threads of said movable turning ring being engaged with said threaded bars to move them forward or backward together;
- a cylindrical cap for engagement with the top surface of said holding means;
- and
- a pin for engagement with one of said holes and one of said ditches when both said hole and said ditch form a joint longitudinal ditch.

A locking device comprising:
- a ring-shaped chuck part having a fixing ring with a group of open ended holes on the top surface of said fixing ring and a movable turning ring being hooped onto said fixing ring with a group of ditches on the top surface of said turning ring and a number of threads on the bottom edge of said turning ring, said chuck part also including three or more movable bars for engagement with said threads of said turning ring to cross said fixing ring separately;
- a cap connected to said chuck part, said cap movable between a first locked position in which it obstructs access to the open interior of said ring-shaped chuck part, and a second unlocked position in which the open interior of said chuck part is accessible;
- and
- a pin for inserting through one of said holes and one of said ditches when one of said holes aligns with one of said ditches to thereby prevent movement of said bars with respect to said chuck part.
