And a moving member in which a slider is used to engage and disengage the elements of the two element tapes. Wherein the pull head may also be referred to as a pull body.

Wherein this first 1 has the chain tooth groove, and chain tooth groove one end is for breaking away from mouthful, the other end is the meshing mouth, and two chain tooth areas extend the entering from two oral areas that break away from the mouth respectively, under the effect of inside cell wall, make two chain tooth areas mesh mutually, after the meshing, extend out from the meshing mouth. In particular, reference is made to the prior art for how the tooth socket of the present head 1 is arranged.

One end of the hook 2 is rotatably connected with the head 1, so that the hook part at the other end can rotate to enter the chain tooth groove. The one end that colludes 2 promptly is the hinged end, realizes rotating with this head 1 through round pin axle 6 and is connected, and the other end that colludes 2 soon has the portion of colluding, and this portion of colluding is arranged in getting into the chain tooth groove to be arranged in the card to go into to the chain tooth area, prevent chain tooth area and this head 1 relative movement, and then play the locking effect. Wherein, the concrete shape and the size of the hook part can be correspondingly arranged according to the requirement, and the prior art can be referred to. Through the rotation of the hook 2, the hook part of the hook 2 moves, and then the hook part enters and exits the chain tooth groove, and when the hook part enters the chain tooth groove, the hook part is clamped into the chain tooth belt, and when the hook part is separated from the chain tooth groove, the hook part is separated from the chain tooth belt.

The elastic element 3 is arranged between the head 1 and the hook 2 to prevent the hook 2 from rotating towards the direction that the hook part is separated from the tooth socket, namely, prevent the hook 2 from moving towards the direction far away from the tooth socket.

When the sliding thrust of the slider is removed, under the action of the elastic force of the elastic element 3, the hook 2 rotates towards the direction that the hook part enters the tooth socket, at the moment, the inclined surface 21 reversely pushes the push rod 5 to slide, and the corresponding slider resets. In the slider, one end of the hook 2 is used as a hinged end to be connected with the slider body 1, and the other end of the hook is used as a hook part, so that the length of the whole hook 2 can be effectively shortened under the condition that unlocking strokes of the hook parts are consistent, and further the whole occupied space is reduced. Simultaneously because catch bar 5 and horse collude one side looks butt that 2 is close to the chain tooth groove, so horse colludes 2 inwards to catch bar 5's effort, and then the slider receives horse colludes 2 effort and faces this head 1 all the time for whole better drawing in together, avoid the slider outwards to break away from this head 1 simultaneously. To sum up, this pull head can solve the not good problem of pull head result of use effectively.

In some embodiments, the head 1 generally includes a first plate 14 and a second plate 15, wherein a chain tooth groove is formed between the first plate 14 and the second plate 15, at the releasing end, a middle portion of an end of the first plate 14 and a middle portion of an end of the second plate 15 are generally connected by a guide (also called a support core), and a mouth portion is formed on each side of the guide to correspond to each of the two chain tooth belts. On both lateral sides, one of the first plate 14 and/or the second plate 15 has a flap to push the teeth of the two chain belts closer together for engagement. And the first panel 14 and the second panel 15 form a cloth belt seam at both lateral sides.

In some embodiments, for convenience of connection, the side of the first plate 14 away from the tooth socket is rotatably connected to the hook 2, that is, the side of the first plate 14 away from the second plate 15, which may also be referred to as an outer side, and the pin 6 is configured to rotatably connect to the hook 2. And a through hole 13 is opened in the middle of the first plate 14, so that the hook part of the hook 2 can penetrate into the through hole 13 and then enter the fastener element groove from the through hole 13. The through hole 13 is generally slightly larger than the hook to ensure the hook to have enough movement space to adapt to the integral rotation of the hook 2.

In some embodiments, further, the side of the first plate 14 away from the chain tooth socket may be provided with a first protrusion 11, i.e. protruding in a direction away from the chain tooth socket. And the middle of the first bulge 11 is provided with an installation groove, and the end part of the hook 2 is positioned in the installation groove and is in rotary connection with the pin shaft 6 penetrating through the wall of the installation groove. When the installation, will collude 2 and elastic component 3 and place according to setting for the position relation well with the horse, then round pin axle 6 penetrates from one side of first arch 11, in the in-process of passing the mounting groove, penetrates to collude 2 matched with hole in the horse. If the elastic member 3 is a torsion spring, it also passes through the central hole of the torsion spring.

In some embodiments, the slider may include a cap 4, the push rod 5 is inserted into the cap 4, the first protrusion 11 is inserted into the cap 4 along the sliding direction of the cap 4, so as to realize a sliding fit, and two sliding walls of the slider respectively abut against two side surfaces of the first protrusion 11 mainly in the axial direction of the pin 6 (and also in the extending direction of the push rod 5), so as to keep the two sliding walls relatively fixed in the direction, i.e. to restrain the two sliding walls from moving relatively in the direction.

In some embodiments, in the juxtaposition direction of the first plate 14 and the second plate 15, the cap 4 may abut against the first plate 14 to support, i.e. prevent, the cap 4 from moving in the direction approaching the tooth socket. And in the direction away from the zipper tooth groove, the pushing piece is stopped by the action of the elastic piece 3 and the inclined surface 21 of the hook 2, so that the cap 4 is stopped. Of course, the cap 4 and the first plate 14 may be directly limited in the parallel direction of the first plate 14 and the second plate 15 by the cooperation of the sliding protrusion and the sliding groove.

Wherein the first protrusion 11 is inserted into the cap 4 along the sliding direction of the cap 4, which makes the cap 4 slide from one end to the main body 1 during assembly, and the first protrusion 11 can slide into the cap 4, so that the assembly is convenient.

And the pushing rod 5 is inserted on the cap 4, namely the pushing rod 5 is inserted into the cap 4 along the extending direction of the pushing rod, and then the slider is assembled.

The cap 4 is then slid in the longitudinal direction, the cap 4 being open at the end, so that the first projection 11 enters the cap 4, at which point the push rod 5 is not yet fitted, so that the cap 4 can be slid directly into place. After the cap 4 is slid into place, the push rod 5 is inserted from the side of the cap 4, and the push rod 5 can pass through the gap between the inclined surface 21 and the first plate 14 during the process of passing through the cap 4 by the push rod 5, and the installation is completed. After the installation, the pushing rod 5 limits the sliding direction to slide under the action of the inclined surface 21, and only when the sliding piece is subjected to an external force, the sliding piece can be longitudinally pushed to overcome the elastic force of the elastic element 3, so as to push the hook 2 to rotate. At the same time, under the action of the inclined surface 21 and the first plate 14, the cap 4 can be limited from moving in the direction perpendicular to the first plate 14.

In some embodiments, in order to better balance the stress of the cap 4 and avoid uneven stress on the cap 4, it is preferable that the first plate 14 is provided with a first protrusion 11 at one end and a second protrusion 12 at the other end, and the through hole 13 is disposed between the first protrusion 11 and the second protrusion 12. Likewise, the second protrusion 12 is slidably engaged with the cap 4 along the sliding direction of the cap 4. The sliding direction of the cap 4 may be a longitudinal direction, and the extending direction of the pin 6 and the push rod 5 may be a transverse direction.

In some embodiments, cap 4 is movably mounted to first projection 11 and second projection 12 in a direction perpendicular to first plate 14, so as to prevent cap 4 from being removed from head 1 in this direction by abutment of first plate 14 with ramp 21.

In some embodiments, it is possible to provide the side of the hook 2 close to the tooth socket with two inclined surfaces 21 arranged in a V-shape. When the sliding piece is positioned at the locking position, namely the pushing piece is positioned at the bottom of the V-shaped structure groove, the pushing piece can slide in two opposite directions to unlock.

In some embodiments, two of said inclined surfaces 21 in a V-shaped arrangement may be made: the inclined plane 21 close to the rotating end of the hook 2 has a smaller inclination angle than the inclined plane 21 far from the rotating end of the hook 2. So as to better adapt to different arm of force lengths, because the inclined plane 21 close to the rotating end of the hook 2 has a shorter arm of force than the inclined plane 21 far away from the rotating end of the hook 2.

As shown in fig. 4, the inclined plane 21 near the rotation end of the hook 2 has an inclination angle of about 29 degrees with respect to the extending direction of the hook 2, and the inclined plane 21 far from the rotation end of the hook 2 has an inclination angle of about 43 degrees with respect to the extending direction of the hook 2.

As shown in fig. 5 and 6, for the acting force F1 between the pushing rod 5 and the inclined surface 21 close to the rotating end of the hook 2 and the acting force F2 between the pushing rod 5 and the inclined surface 21 far away from the rotating end of the hook 2: when the inclination angles of the two inclined surfaces 21 are the same, wherein the acting force F1 is greater than F2, the elastic force of the elastic member 3 can be overcome; when the inclined plane 21 close to the rotating end of the hook 2 is smaller in the inclined angle than the inclined plane 21 far away from the rotating end of the hook 2, the acting force F2 is close to the acting force F1, the difference between the inclined angles is increased until the acting force F2 is equal to the acting force F1, the resistance force for unlocking can be the same by sliding the slider in two directions, and the thrust sense of sliding the slider to two sides can be kept balanced.
