As shown in fig. 1 to 4, which are schematic structural views of one row of the fastener elements 2, a plurality of the fastener elements 2 are connected in series by the connecting core wire 4 to form a fastener element string, and the intervals of the respective fastener elements 2 are substantially uniform. In the following, for the convenience of understanding and explanation, the direction of the fastener element 2 is defined as follows, and as shown in fig. 2 and 5, the direction in which the fastener elements 2 are arranged (i.e., the extending direction of the connecting core wire 4) is defined as the left-right direction from top to bottom as viewed from the top of the fastener element 2, and the left-right direction is referred to as the Y-axis direction herein; the direction perpendicular to the left and right is the front and rear direction, also referred to as the X-axis direction, when viewed in top view; as shown in fig. 3 and 6, the thickness direction of the element body 21 is a vertical direction, also referred to as a Z-axis direction, when viewed from the side of the element 2.

The structure of the fastener element 2 will be further described below, and as shown in fig. 4 to 6, the fastener element 2 is one of the basic units constituting the slide fastener, and the element body 21 at the front end is mainly used to separate or engage with the element 2 body arranged in a mating manner, thereby achieving the opening and closing operation of the slide fastener. The rear end of the tail shank 5 is a member for mounting and connecting with the fabric, wherein the tail shank extends in the fabric direction of the fastener element 2. The integral molding of the tail handle 5 and the tooth main body 21 can well ensure the structural strength of the tooth element 2. Further, the tail shank 5 includes a straight arm portion 51 and a bent arm portion 52, as shown in fig. 9, the straight arm portion 51 and the bent arm portion 52 of the tail shank 5 are combined to have a T-shape, which can prevent the suture thread bound to the straight arm portion 51 from being easily pulled out. Further, the straight arm portion 51 and the bent arm portion 52 of the tail handle 5 may be combined to be in a crutch shape, i.e. in a 7-shape or an L-shape (not shown in the figure), which has substantially the same technical effect as the T-shape. Further, as shown in fig. 4, two handles 5 are disposed at left and right sides of the tooth body 21, and the bent arm portions 52 of the two handles 5 are integrally connected to each other, and the two handles 5 are combined to form a door frame. The door frame-shaped tail handle 5 not only makes the structural strength of the tail handle 5 better, but also makes the suture bound on the straight arm portion 51 or the bent arm portion 52 more stable and not deviate from basically, which is beneficial to improving the connection stability of the fastener element 2 and the fabric. By arranging the tail handle 5 at the tail end of the tooth main body 21 and arranging the tail handle 5 extending backwards, the contact area between the tooth element 2 and the fabric can be increased, so that the tooth element 2 can be better connected with the fabric and is not easy to turn upwards, and the placement stability of the tooth element 2 is improved; in addition, the tail handle 5 which is arranged in a backward extending way increases the connecting area of the suture, thereby greatly reducing the difficulty of suture connection.

For convenience of description, the upper spigot 22 includes an upper transverse edge 221 and an upper vertical edge 222, and the lower spigot 23 includes a lower transverse edge 231 and a lower vertical edge 232. The lower spigot 23 is used for being connected with the installation area 6 of the fabric, the edge part of the installation area is abutted against the lower vertical edge 232 of the lower spigot 23, and the upper surface of the fabric is abutted against the lower transverse edge 231 of the lower spigot 23. As shown in fig. 4 to 5, when seen from the side view of the fastener element 2, the lower vertical edge 232 of the lower spigot 23 is arranged in a front-back staggered manner relative to the upper vertical edge 222 of the upper spigot 22, and the vertical edge height of the upper spigot 22 is shorter than the vertical edge height of the lower spigot 23; the lower spigot 23 is a structure for combining with the fabric, so that the vertical edge of the lower spigot 23 is increased in length for jointing the fastener element 2 with the fabric, thereby being beneficial to improving the connection stability of the fastener element 2 and the fabric. In addition, when the suture thread is bound on the straight arm portion 51 or the bent arm portion 52, the suture thread can be contained in the upper spigot 22, which not only reduces the protrusion of the suture thread bound on the tail handle 5 above the upper side surface of the tooth main body 21, but also enables the suture thread to be far away from the slider 3, thereby reducing the friction between the suture thread and the slider 3 and being beneficial to prolonging the service life of the zipper. In the second embodiment, as shown in fig. 10, the handle 5 is connected to the middle portion of the tooth body 21, and a stepped upper spigot 22 and a stepped lower spigot 23 are formed on the upper and lower sides of the handle 5, respectively, and the upper spigot 22 is substantially aligned with the vertical side of the lower spigot 23. In the third embodiment, the tail handle 5 is connected to the upper position of the tail end of the tooth main body 21, and the upper side surface of the tail handle 5 is flush with the upper side surface of the tooth main body 21, and at this time, a lower spigot 23 is formed at the lower edge of the tail handle 5. Of course, in practical applications, the positions of the tail handles 5 in the first embodiment and the third embodiment may be arranged in a downward position, and the positions and functions of the stepped seam allowance are also opposite, which will not be repeated here.

Further, the center line K of the connecting core wire 4 is arranged at a position not lower than the reference plane where the lower lateral edge 231 of the lower spigot 23 is located, that is, the center line K of the connecting core wire 4 is just located on the extension surface of the step plane where the lower lateral edge 231 of the lower spigot 23 is located; or above the plane of extension of the step plane where the lower lateral edge 231 of the lower spigot 23 is located. Preferably, the center line K of the connecting core wire 4 is disposed between the step plane where the lower lateral edge 231 of the lower spigot 23 is located and the step plane where the upper lateral edge 221 of the upper spigot 22 is located. The effect of this arrangement is that when the thread is bound to the connecting core thread 4, the tightening force of the thread can cause the serial slide fastener 1 to receive a moment of backward overturning, so that the tail handle 5 is better combined with the fabric, the forward overturning of the fastener element 2 can be reduced, and the connection stability of the fastener element 2 and the fabric can be ensured.

As shown in fig. 6 to 8, in order to apply the fabric of the serial slide fastener 1, the fabric includes a mounting area 61 for mounting the slide fastener, and the mounting area 61 of the fabric is arranged on the lower spigot 23 of the element 2 of the serial slide fastener 1 in a direction parallel to the shank 5 so that the shank 5 is positioned above the mounting area 61; wherein the connecting core wire 4 of the serial-type slide fastener 1 is bound to the mounting region 61 by a first suture 71, and the butt handle 5 of the serial-type slide fastener 1 is bound to the mounting region 61 by a second suture 72, in this embodiment, the second suture 72 is bound to the straight arm portion 51 or the bent arm portion 52. Wherein the first suture line 71 is arranged between two adjacent fastener elements 2 in a serging process and is bound on the connecting core wire 4 along the X-axis direction, and can tighten the serial zipper 1 towards the installation area 61 of the fabric, and can prevent the warp and weft of the installation area 61 from loosening; the second stitching 72 pierces the mounting area 61 of the fabric and binds the straight arm 51 and/or the bent arm 52 to the mounting area 61, so that the first stitching 71 and the second stitching 72 fix the serial zipper 1 at least two positions spaced front and back and limit the movement of the serial zipper 1 in three directions of X-axis, Y-axis and Z-axis. The two binding connection parts are respectively arranged at two different positions of the serial connection zipper 1, so that front and back fixing is formed for the serial connection zipper 1, and the tooth main body 21 is not easy to turn over due to the synergistic effect of the two binding connection structures, so that the stability of the zipper is greatly improved.

In order to reduce contact and friction between the first thread 71 and the slider 3, the first thread 71 connected between the connecting core wire 4 and the mounting region 61 is disposed between two adjacent fastener elements 2, and the first thread 71 is not higher than the straight arm portion 51 or the bent arm portion 52 of the butt handle 5. Further, the second suture 72 binds the handle 5, and the tip of the second suture 72 is not higher than the upper surface of the dental body 21, which is also advantageous for protecting the second suture 72 to improve the life span of the fabric.
