the second gap 5 is formed with a track-changing gap 6 for upwardly arching the cloth tape at one end near the split chain column 3. By forming the track-changing gap 6 at one end of the second gap 5 close to the split chain column 3, the track-changing gap 6 can jack up the front end of the cloth belt upwards and then slide downwards along the track-changing gap 6 when the zipper is closed, so that the pull feeling of the whole improved pull head 100 is smoother; when the zipper is opened, the position of the track-changing gap 6 can naturally form forward thrust on the cloth belt, so that the zipper can be opened more easily and easily, and the use experience is excellent.
As a preferred embodiment of the present utility model, a first baffle 21 extends upward from the other side of the lower plate 2, and a first slope 211 is provided at the bottom of the first baffle 21 at an end close to the chain splitting column 3 in an upward inclined manner; a second baffle 11 extends downwards from the other side of the upper plate body 1, and a second slope 111 is obliquely arranged at the bottom of the second baffle 11 at one end close to the chain splitting column 3; the second gap 5 is formed between the first baffle 21 and the second baffle 11, and the track-changing gap 6 is formed between the first slope 211 and the second slope 111. By forming the track change gap 6 by the first slope 211 and the second slope 111, since the slopes are continuous and gradually changed slopes, the resistance is relatively small, and therefore the tape can smoothly slide in the track change gap 6, thereby improving the pull feeling.
More specifically, the upper end of the first baffle 21 is formed with a first horizontal end surface 212 except for the first slope 211, and the lower end of the second baffle 11 is formed with a second horizontal end surface 112 except for the second slope 111, so that the cloth tape can be kept flat in the second gap 5.

Of course, the present utility model is not limited thereto, and the upper end of the first slope 211 may be slightly higher or lower than the top of the third baffle 22 in practical implementation.
More specifically, the third baffle 22 has a third horizontal end surface 221 formed at an upper end thereof, and the fourth baffle 12 has a fourth horizontal end surface 121 formed at a lower end thereof, so that the cloth tape can be kept flat in the first gap 4.
As a preferred embodiment of the present utility model, the inclination angle α of the track-change gap 6 is 40 ° to 50 °. As shown in fig. 3, since the first slope 211 and the second slope 111 of the present utility model are both arc-shaped slopes, the inclination angle α refers to an angle between a middle oblique line and a horizontal straight line of the track-transferring gap 6, and is not the slope of the first slope 211 or the second slope 111. By designing the inclination angle alpha of the track-changing gap 6 to be 40-50 degrees, the pull feeling of the improved pull head 100 can be smoother, and the use experience is improved.
Preferably, the inclination angle α of the track-change gap 6 is 45 °.
As a preferred embodiment of the present utility model, the upper end of the first slope 211 is formed with an arc end surface 2111, which can ensure the smoothness of the improved slider 100 when pulled, and can prevent the upper end of the first slope 211 from scratching or puncturing the cloth tape.
As a preferred embodiment of the present utility model, a cap 7 is further disposed above the upper plate 1, one end of the cap 7 is fixedly connected with one end of the upper surface of the upper plate 1, and a gap 71 is left between the other end of the cap 7 and the upper surface of the upper plate 1, so as to facilitate the installation of the pull tab.
