specifically, the upper and lower pull heads of the structure are completely consistent, a large amount of operation time can be saved in production, and the defect that different pull heads are produced in order to meet the pin piece 1 and the pin piece 2 is avoided only by using the same pull head.
A latch piece 1 is arranged below the lowest zipper tooth of the left zipper strip 3, and a pin piece 2 corresponding to the latch piece 1 in position is arranged below the lowest zipper tooth of the right zipper strip 4;
the latch 1 includes a fixing portion 11 and an extending portion 12, the fixing portion 11 is disposed adjacent to the lowermost fastener element of the left fastener tape 3 at the left fastener tape inside edge 32, and the extending portion 12 extends from the other end of the fixing portion 11 in a direction away from the fastener element and toward the left fastener tape outside edge 31 at the same time, so that the latch 1 is formed to have a curved extending portion 12 and a shape in which the bottom portion thereof extends beyond the left fastener tape inside edge 32:

the curved bending part can guide the baffle plates extending from the two sides of the upper wing plate and the lower wing plate of the pull head, so that the pull head positioned below can be naturally vertical when drooping by matching with the stop part.
Example 2
As shown in the figure, one of the embodiments of the present invention has the main technical scheme substantially the same as that of embodiment 1, and features that are not explained in this embodiment are explained in embodiment 1, and are not described herein. This embodiment differs from embodiment 1 in that: the width of the upper end of the fixing part positioned at one side of the bottommost zipper teeth of the left zipper strip 3 is A;

Specifically, the width of the latch member and the degree of the pin member with the structure are special in that the width of the latch member at the upper end and the lower end along the sliding direction of the pull heads (the width is the width direction of the zipper tape), the latch member can more easily penetrate through the two pull heads and then be clamped and fixed with the pin member, the width of the upper end and the lower end of the fixed pin member corresponds to the latch member on one hand, the pull head positioned below can smoothly extend into the pin member on the other hand, one side of the fixed pin member, which is wider, is abutted with the front port of the pull head, so that the stability is improved, and the firmness of the fixed pin member is also improved.
Further, the stop portion 23 includes an upper stop surface 231 and a lower stop surface 232, the upper stop surface 231 and the lower stop surface 232 near one side of the latch member 1 are simultaneously connected to the inner connecting surface 233, and an outer connecting surface 234 is provided on the other side of the stop portion 23 opposite to the inner connecting surface 233, and is simultaneously connected to the upper stop surface 231 and the lower stop surface 232;
the inner connection surface 233 is formed as an inner side surface of the pin 2 and connected with the meandering portion 22, and the outer connection surface 234 is formed as an outer side surface of the pin 2 and connected with the meandering portion 22;

the surface of the lower blocking surface 232 is provided with a lower protrusion 236 which is in contact with the slider lower wing plate 8 positioned on the side of the right guide groove 6 and is arranged corresponding to the position of the upper protrusion 235.
Specifically, the upper protrusion and the lower protrusion are used for limiting the slider to slide out of the zipper, and the positions of the upper protrusion and the lower protrusion are set, so that the slider can slide on the surfaces of the upper protrusion and the lower protrusion to complete the natural vertical motion of the slider positioned below.
The pull head is directly guided to the stop part after passing through the bending part, and the pull head is indirectly assisted to complete natural vertical actions.
Further, the bottom end surface of the stopper 23 is formed in a shape guiding the stopper 23 to slide in the right guide groove 6 in the width direction of the right fastener tape 4,
the upper protrusion 235 is arranged on the upper baffle surface 231 near one side of the bottom end surface of the stop part 23 in a manner of extending from the inner connection surface 233 to the outer connection surface 234, and is formed into an arc-shaped protrusion with the middle part of the upper protrusion 235 approaching the bottom end surface of the stop part 23, the length of the upper protrusion 235 arranged from the inner connection surface 233 to the outer connection surface 234 is E, E < D, and one side of the upper protrusion 235 far from the bottom end surface of the stop part 23 is formed into an arc-shaped upper sliding surface 237;
the lower protrusion 236 is corresponding to the upper protrusion 235 in position and is consistent in structure, the lower protrusion 236 is arranged on the lower blocking surface 232 near one side of the bottom end surface of the stop part 23 in a manner of extending from the inner connecting surface 233 to the outer connecting surface 234, and is formed as an arc-shaped protrusion, the middle part of the lower protrusion 236 approaches to the bottom end surface of the stop part 23, the length of the lower protrusion 236 arranged from the inner connecting surface 233 to the outer connecting surface 234 is F, f=e, and one side of the lower protrusion 236 far from the bottom end surface of the stop part 23 is formed as an arc-shaped lower sliding surface;
the upper slide surface 237 and the lower slide surface are respectively abutted against the upper wing plate 7 and the lower wing plate 8 of the front end port 10 of the slider on the side of the right guide groove 6, and slide in the width direction of the right fastener tape 4.
Specifically, the width setting ensures that the structural positions of the upper protrusions and the lower protrusions on the stop parts can play a role in guiding and limiting the pull head, and the defect that the pull head and the stop parts are blocked due to the overlarge width of the pull head is avoided. Simultaneously, the arc-shaped arrangement effect is beneficial to the sliding of the pull head on the pull head, and reduces the resistance of the pull head to the stop part when the pull head slides along the width direction of the zipper belt to be in a natural vertical shape.
Further, a side of the upper blocking surface 231 away from the bottom end surface of the stop portion 23 is formed as an upper concave surface 238 concaved inwards toward the stop portion 23, and the upper concave surface 238 is formed as an upper side surface of the pin member 2 and is connected with the meandering portion 22;

Specifically, the setting of concave surface and concave surface down has reduced the drag when the slider slides along the width direction of zipper strip and is the nature vertical form on the one hand to this concave surface down is corresponding with the shape of slider upper flange plate and lower flange plate contact position respectively, and on the other hand, this concave surface down sets up and makes upper portion bellied and bellied structure of lower part more show and plays guide pull head slip and spacing effect, and the pull head is in the bellied guide of upper portion protruding and lower part down along the width direction of right zipper strip when sliding, and the position department that corresponds the pull head respectively at concave surface up and concave surface down is hollow clearance, and this kind of inboard that has guaranteed the upper flange plate of pull head and lower flange plate and the area of contact of backstop portion diminishes, has promoted gliding effect, has reduced the drag.
Further, both side surfaces of the stopper 23 between the upper protrusion 2235 and the lower protrusion 236 are opposite to the bending direction of the bending portion 22, so that the outer side surface 24 of the stopper is convex, and the inner side surface 25 of the stopper is concave corresponding to the outer side surface 24 of the stopper.
Specifically, the structure of the outer side surface and the inner side surface ensures that the direction of the stop part along the sliding direction of the pull head is opposite to the bending part, and the structure is beneficial to the further guiding through the structure of the outer side surface and the inner side surface after the pull head is guided by the bending part so as to finish the natural vertical effect of the pull head.
