Title: RING-TYPE BINDER
Abstract:
A ring-type binder comprises a fixing bar (1) and a movable bar (2). A hook ring (3) used for bearing a document is arranged on the fixing bar (1) and the movable bar (2). Engaging portions at two ends of the fixing bar (1) and the movable bar (2) are arranged with a locking mechanism used for locking the fixing bar (1) and the movable bar (2) when the hook ring (3) is closed and a limiting mechanism used for preventing the movable bar (2) from being separated from the fixing bar (1) when the hook ring (3) is open. An elastic apparatus used for automatically opening the hook ring (3) when the locking mechanism is released is also arranged between the fixing bar (1) and the movable bar (2). The ring-type binder is simple in structure, convenient to use and durable.
