The two sides of the positioning seat connecting plate 31 are hinged with reset hooks 24. The reset hooks 24 are located at the lower end of the snap fastener assembly. When the snap fastener assembly is activated, the elastic reset members are pressed down by the spring brackets 26, so that the positioning seat bracket 20 is driven to move in the vertical direction, thereby driving the positioning seat adjustment plate 29 and the positioning seat connecting plate 31 to move in the vertical direction.

[0030] The lower end of the snap fastener assembly is not tightly attached to the reset hook 24. When the snap fastener assembly is in operation, it can slide relative to the snap fastener positioning seat assembly in the vertical direction under the action of the track limiter, avoiding horizontal movement. During the downward movement of the snap fastener assembly, the elastic reset member is compressed by the action of the spring bracket 26. When the elastic reset member is compressed to the bottom, it will drive the entire positioning seat bracket 20 to move downward. At this time, the lower end of the snap fastener assembly presses against the reset hook and the material to form a stamped snap fastener. After the snap fastener is completed, the snap fastener assembly continues to push the reset hook opening downward.
