Abstract

An actuating mechanism includes a receiving base defining a channel and having a first end portion and a second end portion formed with a cylinder defining a lock hole communicating with the channel, and a retaining post extending from the cylinder. A shackle includes a first end portion and a second end portion defining a lock cavity communicating with the lock hole. A locking member is slidably mounted in the channel and includes a first end portion and a second end portion formed with a locking hook detachably received in the lock cavity. A drive shaft extends through a rotary ring module and includes a first end portion and a second end portion fixedly engaged with the locking member such that the locking member can be moved with the drive shaft synchronously. A circular piece is slidably mounted on the retaining post and is formed with a side extension abutting on the second end portion of the drive shaft. A biasing member is mounted between the circular piece and a pressing member which can be adapted to urge the circular piece which can in turn move the drive shaft via the side extension.
