Fig. 1-Fig. 6 is the structural representation of present embodiment.Wherein Fig. 1 is a perspective view of 1 at the bottom of the slide fastener; Fig. 2 is the perspective view after the 1 assembling spring needle 2 at the bottom of the slide fastener; Fig. 3 is the perspective view after the 1 assembling pulling-on piece 3 at the bottom of the slide fastener; Fig. 4, Fig. 6 are the perspective view of zipper head (integral body); Fig. 5 is the perspective view of cap.

Among the figure, 1, the end 2, spring needle 3, pulling-on piece 4, cap 5, preceding lug boss 6, back lug boss 7, bayonet socket 8, groove 9, fraising 10, recess 11, card 12, purl 13, interior hinge be protruding.

The specific embodiment

With reference to Fig. 1-6, this zipper head, form by the end 1, spring needle 2, pulling-on piece 3 and cap 4, lug boss 5 before the front portion of the upper surface at the end 1 is provided with, the rear portion of 1 upper surface is provided with back lug boss 6 end of at, on preceding lug boss 5, be provided with fraising 9, back lug boss 6 vertically on, be provided with groove 8, rear end at back lug boss 6 is provided with bayonet socket 7; Described spring needle 2 places groove 8, at the middle part of cap 4, be provided with recess 10, recess 10 cooperates with pulling-on piece 3, rear end at cap 4, be provided with card 11, card 11 and bayonet socket 7 buckles extend to form purl 12 downwards at the rear portion of cap 4 movingly, front part sides wall at cap 4, on the position corresponding with 5 fraisings 9 of preceding lug boss, hinge is protruding 13 in being provided with, interior hinge protruding 13 with reamed for 9 hinged cooperations.

Present embodiment, a end promptly preceding lug boss 5 in two positions of projection, 1 upper surface and back lug boss 6 are positions of assembling cap 4, before lug boss 5 to be provided with that a through hole promptly reams 9 are the effects that tighten up and locate cap 4, the bayonet socket of back lug boss 6 plays the spacing positioning action of cap 4.Groove 8 in the middle of the upper surface of end head is positions of assembling spring needle 2, spring needle 2 plays the effect of spring, each makes a call to 1: 13 the front end two sides of cap 4, when assembling cap 4, front part sides wall at cap 4, on the position corresponding with 5 fraisings 9 of preceding lug boss, by getting ready, make the cap inwall form the promptly interior salient point of the protruding 13(of interior hinge), interior salient point forms hinged the cooperation with the through hole of preceding lug boss 5, thereby be fixed tightly on the preceding lug boss 5 of upper surface at the end 1, the recess 10 of design is the position of assembling pulling-on piece 3 in the middle of the cap 4, cap 4 trailing flanks extend to form purl 12 downwards, it is card 11 that the inside bending of cap 4 rear end faces forms the positioning limit position, when pull-up pulling-on piece 3, because cap 4 front ends are positioned on the preceding lug boss 5 of upper surface of end head, and can rotate, so cap 4 rear end perks around described fraising 9, the perk angle is subjected to bayonet socket 7 restrictions, purl 12 breaks away from zipper sprocket, and this moment, slide fastener was in released state, and slide fastener is able to smooth drawing or is pulled away from, spring needle 2 does not play the effect of spring when having pull-up pulling-on piece 2, cap 4 resets, and the origin-location is got back in the rear end, and purl pins zipper sprocket, this moment, slide fastener was in locking-in state, as shown in Figure 6.
