Opening mechanism and sliding zipper

Abstract

The invention relates to an opening (1) comprising: a box (3) defining the receiving space (RS) and the mouth (RA); a mounting pin (2) fitted into the receiving space (RS) through the mouth (RA); and a box pin (4) arranged for the box (3) to orient the mounting pin (2) in the width direction. The box (3) comprises: a base (33) arranged on one side in the width direction relative to the receiving space (RS) and having a box pin (4); and a side wall (34) arranged on the other side in the width direction relative to the receiving space (RS). The side wall (34) comprises: a first gap (SL1) connecting to the receiving space (RS) and the mouth (RA); and a fastening part (342) adjacent to the first gap (SL1) in the mounting direction and fastening to the mounting head (2T) of the mounting pin (2) in the width direction. When the pulling force (F1) is applied to the mounting pin (2) in the direction away from the box pin (4), the mounting end (2T) of the mounting pin (2) moves through the locking part (342), causing the mounting pin (2) to release from the box (3) through the first gap (SL1).
