When a new movable body 2 needs to be replaced, the old movable body 2 is taken down from the slider body 3, the tail part of the limiting hook 54 is obliquely clamped into the limiting groove 61, and the limiting hook 54 arranged in the limiting groove 61 can move up and down in the limiting groove 61 without departing from the limiting groove 61; then, the rotating shaft 511 of the new movable body 2 sequentially penetrates through the first hole 500, the connecting cylinder 510 and the second hole 501, so that the new movable body 2 is movably connected with the slider body 3; at the same time, the elastic piece 50 is fixed to the fixing portion 60, and the assembly of the new movable body 2 to the upper wing plate 6 is completed. The utility model discloses avoided the movable body 2 to damage and changed whole pull head, reduced manufacturing cost.

Further, the movable body 2 includes a pull tab 4, the pull tab 4 is mounted on the movable plate 5, and pulling the pull tab 4 can tilt and separate the second end 53 relative to the slider body 3.

In this embodiment, the tab 4 is used to attach a pull tab.

From the force resolution we find: the smaller the included angle between the resultant pulling force F1 applied by the user and the component force F2 decomposed to the moving direction of the zipper, the more labor-saving the pulling force F1 is needed.

Please refer to fig. 1-6, in this embodiment, applying external force to pull up the second end 53 can with the second end 53 for the separation of slider body 3 perk, draw to have contained angle B between nose 4 and the slider body 3, because the integrated zipper head antedisplacement of impetus phase ratio, the user is at the same position pulling-on piece, and the contained angle a of the pulling force F3 of applying integrative fixed zipper head is great, and applies the utility model discloses a pulling force F1's of the pull head of zip fastener contained angle B is less, so pulls the utility model discloses a zipper head is more laborsaving, makes things convenient for people to smoothly pull the slider body 3, and the condition that the pull head of less zip fastener is blocked takes place.

Further, the nose 4 includes a positioning portion 40, a rotating portion 42, and a return elastic member 41, the rotating portion 42 rotates relative to the positioning portion 40, the return elastic member 41 is disposed between the rotating portion 42 and the movable plate 5, and the return elastic member 41 is used for returning the rotating portion 42.

In this embodiment, the pull tab 4 is a split type, the rotating portion 42 and the elastic return element 41 are disposed at the first end 52, and the positioning portion 40 is disposed at the second end 53.

Because the pull nose 4 is split type, pushes down the rotating part 42, a gap appears between the positioning part 40 and the rotating part 42, and the hand ornament and the small article worn with them can be stored and kept through the gap, so that the pull head of the zipper has the function of storing and keeping the valuable hand ornament and the small article which are small with them, such as earrings, rings, earphones, hand ornaments and the like. And pass through location portion 40 with breach between the rotation portion 42, the person of facilitating the use changes new pulling-on piece, and the structure of drawing nose 4 and the structure of pulling-on piece do not need to match each other, and old pulling-on piece has been bad, can change the pulling-on piece of new different styles wantonly to in the zip fastener production process has been solved, the pulling-on piece die sinking time overlength of particular construction, problem of production cycle length, the utility model discloses a pull head of zip fastener can be produced earlier, reduces the time of waiting for the pulling-on piece production, has improved zip fastener production rate greatly. In the actual life, the pulling-on piece is easy to be broken by the pulling, because the pull-on nose 4 formula as an organic whole of present zip fastener head, new pulling-on piece is difficult to install on the pull head body, and then makes the user can only pull the pull head body with pull nose 4, lacks the pulling-on piece, and pulling force moment has shortened, needs to increase pulling force dynamics and just can pull the pull head body, experiences the sense very poor. The utility model discloses a draw rotation portion 42 of nose 4 to rotate, when needing the pulling-on piece of renewal, only need push down rotation portion 42 advances location portion 40 with the pulling-on piece cover again, loosens rotation portion 42, the pulling-on piece just is fixed in drawing nose 4, the utility model discloses it is very simple, convenient to change the operation of pulling-on piece, has promoted user's experience and has felt.

Further, the rotating portion 42 includes a fixed base 420 and a rotating member 421, the fixed base 420 includes a mounting hole 4200, the rotating member 421 includes a coupling ear portion 4211 and a shaft portion 4212, the shaft portion 4212 is mounted in the mounting hole 4200, and the coupling ear portion 4211 is mounted to the positioning portion 40 through the shaft portion 4212.

In this embodiment, the rotating portion 42 of the pull tab 4 can rotate relative to the positioning portion 40, and one end of the elastic return element 41 is mounted on the fixed seat 420, and the other end is fixedly connected to the rotating element 421.

In this embodiment, connect ear 4211 to establish to the cam structure, be equipped with axial region 4212 in connecting ear 4211, pass through rotating piece 421 the axial region 4212 is installed the mounting hole 4200, rotating piece 421 is in rotate on fixing base 420, push down rotating piece 421, rotating piece 421 rotates, rotating piece 421 with connect ear 4211 no longer to be connected, from rotating piece 421 with connect the breach that appears between the ear 4211, the pull-tab can follow the breach breaks away from or enters into in the nose 4, the convenient pull-tab of renewal. And because draw nose structure and pulling-on piece and need not match each other, old pulling-on piece has been bad, can change the pulling-on piece of new different styles wantonly to in having solved the zip fastener production process, the pulling-on piece die sinking time overlength of special construction, problem that the production cycle is long, the utility model discloses a pull head of zip fastener can be produced earlier, reduces the time of waiting for the pulling-on piece production, has improved zip fastener production rate greatly.

Meanwhile, through the gap between the rotating piece 421 and the connecting ear 4211, the hand ornament and the small object which are worn with the person can be stored, so that the pull head of the zipper has the function of storing and keeping the valuable hand ornament and the small object which are small with the person, such as an earring, a ring, an earphone, a hand ornament and the like.

Loosen rotation piece 421, the elastic component 41 that resets will rotation piece 421 bounces and resets, rotation piece 421 with connect ear 4211 to cooperate to be connected and prevent to install the pulling-on piece that draws in the nose 4 and break away from, the pulling-on piece installation is accomplished.

Further, the positioning portion 40 includes a protrusion 400, the rotating portion 42 includes a groove, the protrusion 400 abuts against the groove, and the positioning portion 40 is connected to the rotating portion 42.

The utility model discloses utilize lever principle, fly leaf 5 is the lever, fly leaf 5 can pass through flexure strip 50 with 3 swing joint of the slider body, fly leaf 5 with 3 junctions of the slider body are the fulcrum, it is right external force is applyed to second end 53, makes second end 53 for the slider body 3 rotates the perk, and then drives first end 52 pushes down, flexure strip 50 is suppressed. Because the elastic piece 50 has resilience, the external force applied to the second end 53 is removed, the elastic piece 50 bounces the first end 52, and then the second end 53 is driven to reset, and the second end 53 is attached to the slider body 3.

In the present embodiment, the movable plate 5 is movably connected to the upper wing plate 6 through the connecting portion 51, the connecting portion 51 is a fulcrum of the movable plate 5, the movable plate 5 is a lever, and the rotation of the second end 53 drives the rotation of the first end 52.

Of course, the present invention can also have other various embodiments, and based on the embodiments, those skilled in the art can obtain other embodiments without any creative work, and all of them belong to the protection scope of the present invention.
