the shaft connecting part is also provided with a shaft hole; the pin shaft penetrates through a shaft hole of the shaft connection part, and the shaft connection part is connected with the two lugs through the shaft pin.
4. The pull head of claim 3, wherein one end of the pin has an axial interference pattern on its outer circumferential surface, and the other end of the pin is smooth; during the installation, the round pin axle inserts the shaft hole of one side lug, the shaft hole of coupling portion and the shaft hole of opposite side lug with smooth end earlier in proper order, inserts and is fixed in the shaft hole through the shaft hole interference fit of full ripples and one side lug until full ripples end.
5. The slider according to claim 1, wherein a claw hole is formed in the upper wing plate, penetrates through the upper wing plate from top to bottom and is communicated with the Y-shaped zipper combining channel; the end part of the pull plate is provided with a corresponding claw, when the pull plate is horizontally placed, the claw penetrates through the claw hole to be inserted into the Y-shaped chain combining channel, and when the pull plate is lifted, the claw is lifted away from the claw hole.
6. The pull head of claim 5, wherein the pawl aperture is positioned such that a portion of the pawl aperture is located within the first arcuate recess and another portion of the pawl aperture is located in the upper wing surface outside of the first arcuate recess; correspondingly, one part of the claw is protruded at the shaft connecting part, and the other part of the claw is protruded in the pull plate ventral surface outside the shaft connecting part; the claw hole is located on the opposite side of the second arcuate depression, i.e. the side adjacent the other lug.
7. The slider according to claim 1, wherein both ends of the second arc-shaped recess are provided with riveting protrusions, and when the spring plate is mounted, the riveting protrusions are riveted towards the spring plate to fix the spring plate; the pull plate is characterized in that the pull plate ventral surface is provided with a concave position which is positioned at a position corresponding to the riveting convex at the same side, and when the pull plate ventral surface is horizontally placed downwards, the concave position is used for avoiding a structure after the riveting convex position is riveted; and the riveted structure at the riveting convex part is used for propping the contact concave position to ensure that the web surface of the pull plate does not contact with the upper surface of the upper wing plate.
8. The slider according to claim 1, wherein the second arc-shaped concave recess has two ends, one end is a rivet protrusion and the other end is a concave cap, when the elastic piece is installed, one end of the elastic piece is inserted into the concave cap first, and the other end is riveted and fixed by the rivet protrusion; the pull plate is characterized in that the ventral surface of the pull plate is provided with a concave position which is positioned at the position corresponding to the riveting convex/concave cap at the same side, and when the pull plate is horizontally placed downwards, the concave position is used for avoiding the riveted structure/concave cap at the riveting convex position; and the riveted structure/concave cap at the riveting convex part is used for propping the concave position so that the web surface of the pull plate does not contact with the upper surface of the upper wing plate.
9. The pull head of claim 1, wherein the second arcuate recess is a full-segment arcuate recess, or has arcuate recesses at both ends and a planar recess in the middle; the concave bottom of second arc is equipped with a bump for the shell fragment is contradicted the shell fragment when downward warping, prevents that the shell fragment from pasting the concave bottom surface of second arc.
10. The pull head of claim 1, wherein the upper wing plate upper surface is planar; the lug is an arch bridge-shaped lug and is integrally formed on the upper wing plate.
