Quick-release engagement device
A quick-release engagement device for a female threaded member includes a tubular member and an actuating unit. The tubular member includes a contractible portion which has a male threaded segment and an actuated segment, and which is divided into a plurality of contractible sectors by a plurality of slits. The actuating unit is configured to press the actuated segment to permit the contractible sectors to deform synchronously from an expanded state, where the female threaded member is permitted to be in threaded engagement with the male threaded segment, to a contracted state, where the female threaded member is permitted to be quickly sleeved on or removed from the male threaded segment.
