Zipper slider with automatic resetting and locking function

A zipper slider with an automatic resetting and locking function, comprising a zipper slider body comprising an upper plate and a lower plate which are integrally connected by a support core, wherein the zipper slider further comprises a torsion member, an elastic piece, a first elastic member and a second elastic member which are installed at a top of the upper plate,

• the elastic piece is provided with an acting end and a locking pin end, and the acting end of the elastic piece is disposed above an end of the first elastic member and jacked by the end of the first elastic member,
• the torsion member is movably connected to the upper plate and located above the elastic piece, and a bottom of the torsion member is provided with an avoidance notch adapted to the acting end,
• the second elastic member is disposed on a moving path of the torsion member, and torsion of the torsion member can drive the second elastic member to undergo elastic deformation, and
• the upper plate is further provided with a through hole for allowing the locking pin end to pass through downward;
• when the torsion member is twisted without an external force, the second elastic member extends, the acting end is located in the avoidance notch, and the first elastic member extends to maintain jacking the acting end upward, and at this time, the locking pin end moves downward to pass through the through hole and enter a position below the upper plate, so that the locking pin end is clamped into zipper teeth, and the zipper slider is maintained in a stopped state;
• when the torsion member is twisted by the external force, the second elastic member is compressed, and the avoidance notch is far away from the acting end, so that the torsion member presses the acting end downward, and the first elastic member is compressed, and at this time, the locking pin end is tilted upward to be detached from the zipper teeth, and the zipper slider is in an unlocked state and can slide along the zipper teeth;
• and
• after the external force is removed, the second elastic member extends to twist the torsion member, the avoidance notch moves in a direction of the acting end to be reset, the acting end enters the avoidance notch again, and the zipper slider enters the stopped state again and is maintained in the stopped state.
