  • Patent number: 6226840
    Abstract: A binding clip having actuator rods capable of rotation to any angle so as to not impair reading and writing, and which is produced by a simpler fabrication process. A triangularly folded pincer section has an actuator rod on each of the two sides and an insertion hole punched in each of the two sides. An even number of oppositely facing limiter notches are formed along the inner circumference of the insertion holes and a rounded guide element is disposed in between each of the limiter notches, providing for the rotation to any angular degree of the actuator rods along the rounded guide elements. The actuator rods consist of U-shaped rod structures with the two ends bent to an appropriate angular degree and having catch hooks extending from the bent sections. By pressing the two sides of the actuator rods inwardly, the catch hooks can engage opposing pairs of limiter notches such that the actuator rods remain fullly pivotable while positioned in the limiter notches.
