[0019] A zipper, such as Figure 1-Figure 4 As shown, it includes a zipper tape 1 sewn on both sides of the opening of the clothes, a plurality of chain teeth 2 fixedly connected to the zipper tape 1, an upper stop 3 and a lower stop 4 fixedly connected to both sides of the zipper tape 1, and a first slider 5 slidably connected to any one of the zipper tapes 1, a second slider 6 is slidably connected to the other zipper tape 1, and the second slider 6 is detachably connected to the lower stop 4 through a connecting member, a connecting groove 7 for the second slider 6 to be inserted is provided inside the first slider 5, and a locking member is provided on the first slider 5. When the lower stops 4 on the two zipper tapes 1 are aligned with each other, the positions of the second slider 6 and the connecting groove 7 correspond to each other, and when the second slider 6 completely slides into the connecting groove 7, the locking member fixes the second slider 6 in the connecting groove 7, and a pull plate 8 is provided on the first slider 5. When the second slider 6 and the connecting groove 7 are fixed to each other, the pull plate 8 drives the first slider 5 to slide through a driving member; The connecting member includes a receiving groove 9 provided on the second slider 6 for receiving the bottom stop 4, and a magnetic sheet 10 fixedly connected to the inner wall of the receiving groove 9 and the outer wall of the bottom stop 4 and attracted to each other. When the clothes are opened, the second slider 6 and the bottom stop 4 can be fixed to each other by the mutual attraction between the magnetic sheets 10 to prevent them from sliding on the zipper tape 1, thereby facilitating the mutual connection between the first slider 5 and the second slider 6 after the bottom stop 4 is aligned. The locking member includes a connecting block 11 fixedly connected to the side wall of the second slider 6 for being inserted into the connecting groove 7. When the two lower stops 4 are aligned with each other, the positions of the connecting block 11 and the connecting groove 7 correspond to each other. A mounting groove 12 is provided in the connecting groove 7. A card bead 14 is connected to the mounting groove 12 through a spring 13. When the spring 13 is in a normal state, the card bead 14 and the notch of the mounting groove 12 fit each other. A card slot 15 for the card bead 14 to be inserted is provided on the side wall of the connecting block 11. When the connecting block 11 contacts the bottom of the connecting groove 7, the card bead 14 and the card slot 15 correspond to each other, and the two zippers at the opening of the clothes are locked. The lower stops 4 on the belt 1 are aligned with each other, and then the connecting block 11 on the side wall of the second slider 6 is inserted into the connecting groove 7 on the first slider 5. In the process of the connecting block 11 moving toward the bottom of the connecting groove 7, the connecting block 11 squeezes the card bead 14 to force it to move toward the bottom of the installation groove 12. At this time, the spring 13 is in a compressed state. When the connecting block 11 moves to contact the bottom of the connecting groove 7, the card bead 14 and the card groove 15 correspond to each other, and the spring 13 returns to its original state and forces the card bead 14 to be inserted into the card groove 15, thereby achieving the effect of fixing the connecting block 11 in the connecting groove 7; The driving member includes a sliding groove 16 provided on the first slider 5, a sliding rod 17 rotatably connected to the pull plate 8 and slidably connected to the sliding groove 16, a positioning groove 18 is provided on the connecting block 11, and when the connecting block 11 and the connecting groove 7 are connected to each other, the positioning groove 18 and the sliding groove 16 correspond to each other, and the sliding rod 17 and the positioning groove 18 are detachably connected to each other through a buckle 19. After the connecting block 11 and the connecting groove 7 are connected to each other, the pull plate 8 is pushed toward the side of the positioning groove 18 to force the sliding rod 17 to slide toward the side of the positioning groove 18. After the sliding rod 17 and the positioning groove 18 are connected to each other by the buckle 19, the pull plate 8 is pulled to drive the first slider 5 and the second slider 6 to slide along the zipper tape 1, so as to achieve the effect of meshing the chain teeth 2, thereby closing the opening on the clothes; A limiting groove 20 is provided on the inner wall of the sliding groove 16, and a limiting block 21 slidably connected to the limiting groove 20 is fixedly connected to the side wall of the sliding rod 17 to prevent the sliding rod 17 from being separated from the sliding groove 16, thereby preventing the pull plate 8 and the first pull head 5 from being separated from each other; The end of the sliding rod 17 away from the sliding groove 16 is fixedly connected to a connecting seat 22, and a pull ring 23 is fixedly connected to the pull plate 8. A rotating groove 24 for the pull ring 23 to rotate is provided on the connecting seat 22. The rotation groove 24 and the pull ring 23 cooperate with each other to realize the rotation connection between the pull plate 8 and the sliding rod 17, thereby avoiding contact between the pull ring 23 and the sliding rod 17, thereby avoiding the reduction of the service life of the sliding rod 17 due to mutual friction during rotation; The inner wall of the rotating groove 24 is fixedly connected with a buffer layer 25, and the pull ring 23 is rotatably connected in the buffer layer 25 to prevent the pull ring 23 from directly colliding with the inner wall of the rotating groove 24 during use, thereby increasing the service life of the pull ring 23 and further increasing the service life of the pull plate 8.

[0020] The present invention is normally used as follows: The second slider 6 is connected to the bottom stop 4 by using a connecting piece, and then the first slider 5 is slid until it fits with the bottom stop 4 on its own zipper tape 1, and then the bottom stop 4 on the other zipper tape 1 is aligned with it, and then the second slider 6 is inserted into the connecting groove 7 on the first slider 5 until the second slider 6 is completely inserted into the connecting groove 7. At this time, the second slider 6 is fixed in the connecting groove 7 by using a locking piece to realize the mutual connection between the second slider 6 and the first slider 5, and then the restriction of the connecting piece on the second slider 6 is cancelled to separate it from the bottom stop 4, and then the driving piece is used to drive the pull plate 8 to drive the first slider 5 to move along the zipper tape 1 to engage the chain teeth 2 and close the opening of the clothes. In this process, the pulling of the first slider 5 is prevented from being affected by the misalignment of the bottom stop 4, thereby ensuring the normal use of the zipper and preventing damage to the zipper caused by forced pulling.

[0021] The above is only a preferred embodiment of the present invention, and the protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
