DETAILED DESCRIPTION OF THE EMBODIMENTS

(10) The specific embodiments of the present invention will be further described hereinafter with reference to the drawings.

(11) As shown in FIGS. 1-7, the dock slider of the present embodiment includes the guide column 3. The upper wing plate 1 and the lower wing plate 2 are connected by the guide column 3. The guide column 3 is provided on the front end side 41 of the slider. The space formed between the upper wing plate 1 and the lower wing plate 2 forms the sliding groove 4. The upper guide plate 5 is downwardly and vertically provided from the left edge and the right edge of the upper wing plate 1, respectively. The upper guide plate 5 is configured to limit the sliding direction of the slider. The lower guide plate 6 is upwardly and vertically provided from the left edge and the right edge of the lower wing plate 2, respectively. The lower guide plate 6 is configured to limit the sliding direction of the slider and arranged corresponding to the upper guide plate. The upper wing plate 1 is provided with the through hole 10 penetrating from the surface of the upper wing plate 1 to the sliding groove 4. The upper wing plate 1 is provided with the puller holder 101. The puller holder 101 is provided with the self-locking piece 102 extending into the through hole 10.

(12) The upper wing plate 1 and the lower wing plate 2 are respectively provided with the upper limit portion 7 and the lower limit portion 8 at sites adjacent to the rear end side 42 of the slider. The space surrounded by the upper limit portion 7 and the lower limit portion 8 forms the limit cavity 9 configured to accommodate the rear end side 42 of the slider. The cross-sectional area of the limit cavity 9 is larger than the cross-sectional area of the sliding groove 4 at the rear end side 42 of the slider.

(13) The upper limit portion 7 includes two upper clasping bodies 71 symmetrically arranged with respect to the center line of the upper wing plate 1. The lower limit portion 8 includes two lower clasping bodies 81 symmetrically arranged with respect to the center line of the lower wing plate 2.

(14) The limit cavity 9 formed by the two upper clasping bodies 71 and the two lower clasping bodies 81 is rectangular and configured to limit a lateral movement of the rear end side 42 of the slider.

(15) The upper clasping body 71 includes the upper connecting piece 74. The upper blocking piece 72 and the upper side blocking piece 73 are connected and fixed by the upper connecting piece 74.

(16) The upper wing plate 1 smoothly extends in a direction away from both the rear end side 42 of the slider and the surface of the upper wing plate 1 to form the upper blocking piece 72. The upper guide plate 5 extends away from the rear end side 42 of the slider to form the upper side blocking piece 73 corresponding to the outer edge of the upper blocking piece 72. The upper connecting piece 74 is arranged between the upper blocking piece 72 and the upper side blocking piece 73 and arranged corresponding to the outer edge of the upper blocking piece 72.

(17) The end of the upper side blocking piece 73 is gradually contracted toward the upper wing plate 1 and connected to the upper connecting piece 74 to form the upper sliding outer arc surface 75.

(18) The upper sliding strip 11 is provided on the inner side of the upper guide plate 5 along the sliding direction of the slider. The upper sliding strip 11 is connected to both the upper guide plate 5 and the upper wing plate 1. The end of the upper sliding strip 11 is gradually contracted toward the rear end side 42 of the slider to form the upper sliding inner arc surface 12.

(19) The upper wing plate 1 between the two upper sliding inner arc surfaces 12 is provided with the upper rear end slope 13 configured to facilitate sliding the slider. The upper rear end slope 13 is a smooth arc-shaped end surface formed by the inner surface of the upper wing plate 1 gradually contracting toward the outer surface of the upper wing plate 1.

(20) The inner surface of the upper sliding strip 11 adjacent to the rear end side 42 of the slider is provided with the upper opening arc surface 14 configured to reduce the sliding resistance of the slider.

(21) The lower clasping body 81 includes the lower connecting piece 84. The lower blocking piece 82 and the lower side blocking piece 83 are connected and fixed by the lower connecting piece 84.

(22) The lower wing plate 2 smoothly extends in a direction away from both the rear end side 42 of the slider and the surface of the lower wing plate 2 to form the lower blocking piece 82. The lower guide plate 6 extends away from the rear end side 42 of the slider to form the lower side blocking piece 83 corresponding to the outer edge of the lower blocking piece 82. The lower connecting piece 84 is arranged between the lower blocking piece 82 and the lower side blocking piece 83 and arranged corresponding to the outer edge of the lower blocking piece 82.

(23) The end of the lower side blocking piece 83 is gradually contracted toward the lower wing plate 2 and connected to the lower connecting piece 84 to form the lower sliding outer arc surface 85.

(24) The lower sliding strip 21 is provided on the inner side of the lower guide plate 6 along the sliding direction of the slider. The lower sliding strip 21 is connected to both the lower guide plate 6 and the lower wing plate 2. The end of the lower sliding strip 21 is gradually contracted toward the rear end side 42 of the slider to form the lower sliding inner arc surface 22.

(25) The lower wing plate 2 between the two lower sliding inner arc surfaces 22 is provided with the lower rear end slope 23 configured to facilitate sliding the slider. The lower rear end slope 23 is a smooth arc-shaped end surface formed by the inner surface of the lower wing plate 2 gradually contracting toward the outer surface of the lower wing plate 2.

(26) The inner surface of the lower sliding strip 21 adjacent to the rear end side 42 of the slider is provided with the lower opening arc surface 24 configured to reduce the sliding resistance of the slider.

(27) As shown in FIGS. 8-9, when the slider in the present embodiment is combined with an ordinary slider, the rear end side of the ordinary slider is accommodated in the limit cavity 9. The rear end side of the ordinary slider can easily slide into the limit cavity 9 by the upper clasping body 71 and the lower clasping body 81 without being separated and misaligned. In this way, when the double-slider zipper is in use, the bottom stop member easily passes through the sliding grooves of the two sliders at the same time, which is user-friendly.

(28) According to the disclosure and teachings of the above description, those skilled in the art can also make changes and modifications to the above-mentioned embodiments. However, the present invention is not limited to the specific embodiments described above, and these modifications and changes made to the present invention shall fall within the scope of protection of the claims of the present invention.
