本发明涉及一种环形装订夹机构，包括细长的托架和由托架支承以相对于托架移动的环支承件。该环支承件具有上表面和下表面。环形装订夹机构设有多个用于保持活页的环。各个环包括第一环体和第二环体，第一环体安装在环支承件上，以与环支承件一起相对于托架在闭合位置和打开位置之间移动。致动件安装在托架上以相对于托架进行枢转运动，从而将环从闭合位置移动至打开位置。致动件与环具有卡锁连接。
摘要（英）：

A ring binder mechanism includes an elongate housing and a ring support supported by the housing for movement relative to the housing. The ring support has an upper surface and a lower surface. A plurality of rings is provided for holding loose-leaf pages. Each ring includes a first ring member and a second ring member. The first ring member is mounted on the ring support for movement with the ring support relative to the housing between a closed position and an opened position. An actuator is mounted on the housing for pivotal movement relative to the housing for moving the rings from their closed position to their opened position. The actuator has a snap-lock connection with the housing.
