[0023] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0024] This embodiment is a zipper that is easy to replace.

[0025] like Figure 1-4 As shown, the zipper includes a fabric tape 1 and a zipper head 5. There are two sets of fabric tape 1. Each set of fabric tape 1 has a tooth 4 fixedly installed on one side. The upper end of the tooth 4 is fixedly installed with an upper stop 3, and the lower end of the tooth 4 is fixedly installed with a lower stop 2. The zipper head 5 includes a pull head 6, a pull tab 7, and a connecting component 8. The pull head 6 is connected to the tooth 4. The pull tab 7 is connected to the pull head 6 through the connecting component 8. The connecting component 8 includes a fixing block 10, a limiting hole 11, an insertion groove 12, a first guide hole 13, a mounting groove 14, a guide rod 15, a movable rod 16, a second guide hole 17, an upper inclined wedge block 18, a limiting block 19, and a compression spring 20. A snap-fit ​​hole 9 is opened at one end of the upper outer surface of the pull tab 7.

[0026] The fixing block 10 is fixedly installed on the upper outer surface of the pull head 6. The insertion groove 12 is opened in the middle of the upper outer surface of the fixing block 10. The limiting hole 11 is opened below the insertion groove 12. The pull tab 7 passes through the limiting hole 11 through the snap-fit ​​hole 9. The first guide hole 13 is opened in the middle of one side of the insertion groove 12. The mounting groove 14 is opened in the lower part of the end of the first guide hole 13 away from the insertion groove 12. The movable rod 16 is located in the first guide hole 13. The second guide hole 17 is opened on the outer surface of one end of the movable rod 16. The upper inclined wedge 18 is fixedly installed on the outer surface of one end of the movable rod 16. The outer surface of one end of the guide rod 15 is connected to the rear of the first guide hole 13. The movable rod 16 and the outer wall of the upper inclined wedge block 18 are slidably connected to the first guide hole 13. The movable rod 16 is slidably connected to the outer wall of the guide rod 15 through the second guide hole 17. The limiting block 19 and the compression spring 20 are both located in the mounting groove 14. The limiting block 19 is fixedly installed on the lower outer surface of the movable rod 16 away from the upper inclined wedge block 18. The compression spring 20 is fixedly installed between one side of the outer surface of the limiting block 19 and one end of the mounting groove 14. One side of the outer surface of the limiting block 19 is elastically connected to one end of the mounting groove 14 through the compression spring 20. The outer wall of the limiting block 19 and the mounting groove 14 are slidably connected.

[0027] It should be noted that this utility model is a zipper that is easy to replace. The fabric tape 1, lower stop 2, upper stop 3, tooth 4, and zipper head 6 described in this article are all prior art and can be effectively known to those skilled in the art. Specific details will not be elaborated further. The connecting component 8, when connecting the pull tab 7 and the zipper head 6, only requires inserting one end of the pull tab 7 located in the snap-fit ​​hole 9 into the insertion groove 12 to achieve installation. The pull tab 7, inserted into the insertion groove 12, presses against the upper inclined wedge block 18, causing the upper inclined wedge block 18 and the movable rod 16 to slide along the first guide hole 13. The movable rod 16 passes through the second guide hole 17. Sliding along the outer wall of the guide rod 15 causes the upper inclined wedge block 18 to move toward the first guide hole 13. The movable rod 16 drives the limiting block 19 to press the compression spring 20 in the mounting groove 14. When one end of the pull piece 7 is inserted into the central axis of the limiting hole 11, the reaction force of the compression spring 20 causes the upper inclined wedge block 18 to reset. The pull piece 7 passes through the locking hole 9 and the limiting hole 11. The upper inclined wedge block 18 limits the pull piece 7, thus achieving installation. It is also easy to disassemble. When disassembling, it is only necessary to press the upper inclined wedge block 18 so that one end of the upper inclined wedge block 18 is inserted into the first guide hole 13, and the pull piece 7 can be pulled out, which is convenient for operation.
