Safety paper clip, has intermediate leg connected with leg of outer leg pairs via bridge, and end leg connected with idle front end, where length of end leg corresponds to length of intermediate leg of inner leg pairs

摘要

The clip (1) has u-shaped inner leg pairs (9), whose intermediate leg (13) is connected with a leg (21) of outer leg pairs (5) via a bridge (17). An end leg (25) is connected with an idle front end (29). Length (l1) of the end leg corresponds to length (L1) of the intermediate leg of the u-shaped inner leg pairs, where the length of the intermediate leg ranges between 0 to 0.5. Length of the end leg is equal to inner half width of another outer leg pairs. The front end is spaced from the leg of the former outer leg pairs. The front end is designed in a blunted manner.
