[0017] Please refer to Figure 1 , the present utility model provides an auxiliary fixing device for lacing installation through improvement, including a lacing 1 and an auxiliary structure 2. The inner side of the lacing 1 is movably attached to the auxiliary structure 2, and the setting of the auxiliary structure 2 enables the lacing 1 to better complete the installation work.

[0018] Please refer to Figure 2 , the present utility model provides an auxiliary fixing device for lacing installation through improvement. The auxiliary structure 2 includes a housing 21, a limiting groove 22, a feeding bin 23, a feeding pipe 24, a sliding rod 25, a spring 26, a push rod 27 and a handle 28. A limiting groove 22 is opened at the upper left end of the housing 21. At the upper left end of the inner top of the housing 21, a feeding bin 23 is provided. The feeding bin 23 is arranged at the upper left end of the housing 21. The height of the lower outlet position of the feeding bin 23 and the bottom of the feeding pipe 24 can only place one lacing 1, and the lower end of the feeding bin 23 penetrates through the top of the feeding pipe 24 and is suspended at the upper left end inside the feeding pipe 24. A horizontal feeding pipe 24 is opened in the middle and lower part of the inner side of the housing 21. A chute is opened in the middle of the bottom end of the feeding pipe 24, and the middle of the bottom end of the feeding pipe 24 is slidably connected with the sliding rod 25. The middle part of the inner side of the feeding pipe 24 is slidably connected with the sliding rod 25. A horizontal top plate is arranged in the middle of the upper left end of the sliding rod 25, and the length of the arranged horizontal top plate is greater than the length of the arranged sliding rod 25. The lower right end of the sliding rod 25 is fixed to the spring 26, and the upper right end of the sliding rod 25 is integrally fixed to the push rod 27, and the right end face of the push rod 27 is fixed to the handle 28. The lacing 1 is placed inside the feeding bin 23, and the setting of the handle 28 also facilitates the staff to work more labor-saving.

[0019] The working process is as follows:

[0020] 1. When the staff needs to install the lacing 1, first place the lacing 1 to be installed into the feeding bin 23. The staff can align the limiting groove 22 with the top of the zipper head lock hoop and make it snap into the limiting groove 22. Then, the staff pulls the handle 28 outwards, and thus the push rod 27 will extend outwards synchronously. During this process, the sliding rod 25 will be compressed by the spring 26;

[0021] Second, after reaching a certain spring potential energy, the spring potential energy can be used to push the slide bar 25 out towards the left end of the housing 21. The horizontal top plate at the upper left end of the slide bar 25 can push the pull tab 1 out from the material conveying pipe 24, so that the pull tab 1 can be inserted into the lock hoop at the top end of the zipper head. Repeating this process, the pull tabs 1 in the feeding bin 23 will successively fall into the material conveying pipe 24 and then be inserted into the lock hoop by the spring potential energy (because there is a gap between the tail end of the lock hoop and the top of the zipper head).
