[0024] Reference Figure 1 As shown, one embodiment of this application provides a non-exposed zipper sewing auxiliary device, including a main body 1, a first extension 2, a second extension 3, a movable member 4, a first limiting member 5, and a second limiting member 6. The first extension 2 and the second extension 3 are arranged at intervals relative to each other, and one side of each is connected to the main body 1. The length direction of both the first extension 2 and the second extension 3 is along a first direction. The movable member 4 is disposed on the first extension 2 and is movable along the first direction. The first limiting member 5 is connected to the movable member 4 and is located between the first extension 2 and the second extension 3. The second limiting member 6 is disposed on the second extension 3 and is located between the first extension 2 and the second extension 3. The first extension 2, the second extension 3, the first limiting member 5, and the second limiting member 6 form a clearance channel 7 for fabric to pass through.

[0025] Refer again Figure 1 As shown, exemplarily, Figure 1 The X direction in the diagram is the first direction. The aforementioned toothless zipper sewing auxiliary device can be used in the textile industry for sewing toothless zippers to fix the zipper thread. In use, the zipper is threaded along its length into the clearance channel 7, and one side of the zipper teeth is attached to the surface of the second limiting member 6. Simultaneously, for zippers of different specifications or sizes, the position of the moving member 4 on the first extension 2 can be adjusted along the first direction, so that the first limiting member 5 is attached to the edge of the folded edge on the other side of the zipper. The first limiting member 5 and the second limiting member 6 fix the two edges of the zipper, and then the zipper and fabric are sewn together. The toothless zipper sewing auxiliary device of this application ensures a firm and smooth bond between the zipper and the garment fabric, thereby improving the efficiency and accuracy of zipper sewing and reducing the appearance quality problem of uneven folded edge width.

[0026] Reference Figure 2 As shown, in some embodiments, the first extension 2 is provided with a hollow track 14 arranged along a first direction in the length direction. The moving member 4 includes a pair of pressure plates 41 respectively disposed on two opposite sides of the first extension 2. The moving member 4 also includes a connecting rod 42, which passes through the hollow track and connects to the pair of pressure plates 41.

[0027] The position of the movable member 4 on the first extension 2 can be adjusted by means of the connecting rod 42 and the pair of pressure plates 41. When it is necessary to adjust the position of the movable member 4, the connecting rod 42 is adjusted to reduce the pressure of the pair of pressure plates 41 on the first extension 2. Then, the movable member 4 is adjusted to a suitable position by moving the connecting rod 42 in the hollow track 14. Finally, the connecting rod 42 is adjusted to increase the pressure of the pair of pressure plates 41 on the first extension 2, thereby fixing the position of the movable member 4 on the first extension 2.

[0028] In some embodiments, the connecting rod 42 and a pair of pressure plates 41 are connected by threads.

[0029] In some embodiments, the length directions of the first limiting member 5 and the second limiting member 6 are both arranged along the second direction, which is perpendicular to the first direction.

[0030] Refer again Figure 1 As shown, exemplarily, Figure 1 The Z-direction is the second direction. In actual use, the main body 1 is placed on the work surface, and the second extension 3 is closer to the work surface than the first extension 2. For example, Figure 1 The Y-direction can be the vertical direction.

[0031] In some embodiments, the non-exposed zipper sewing aid further includes a third limiting member 8. The third limiting member 8 is disposed on the surface of the second extension 3 away from the first extension 2. The length direction of the third limiting member 8 is arranged along the second direction.

[0032] When the zipper tooth-less sewing auxiliary device is in use, when the zipper tooth side of the device is attached to the surface of the second limiting member 6 in the clearance channel 7, the edge of the fabric below it can contact the side of the third limiting member 8, thereby limiting the position of the fabric and facilitating sewing.

[0033] In some embodiments, along the first direction, the second limiting member 6 is located between the first limiting member 5 and the third limiting member 8.

[0034] Along the first direction, the second limiting member 6 is located between the first limiting member 5 and the third limiting member 8, which facilitates determining the setting position of the zipper on the fabric surface.

[0035] In some embodiments, along the second direction, the length of the third limiting member 8 is greater than that of the first limiting member 5 and the second limiting member 6.

[0036] In some embodiments, the non-exposed zipper sewing aid further includes a first support member 12. One side of the first support member 12 is connected to the third limiting member 8, and the other side is connected to the second extension 3. The first support member 12 is used to support the third limiting member 8.

[0037] In actual use, when the third limiting member 8 comes into contact with the edge of the fabric, the side of the third limiting member 8 away from the second extension 3 may come into contact with the operating table surface and be subjected to pressure. The first support member 12 is connected to the third limiting member 8 and the second extension 3 on both sides respectively. The first support member 12 is used to support the third limiting member 8, which can reduce the risk of damage to the third limiting member 8.

[0038] In some embodiments, along the first direction, the third limiting member 8 is disposed between the first support member 12 and the second limiting member 6.

[0039] In some embodiments, the non-exposed zipper sewing aid further includes a first connector 9, a second connector 10, and a telescopic member 11. The first connector 9 and the second connector 10 are both disposed on the surface of the first extension 2 away from the second extension 3, and the telescopic member 11 is disposed between the first connector 9 and the second connector 10 and connects the first connector 9 and the second connector 10.

[0040] A first connector 9 and a second connector 10 are provided on the surface of the first extension 2 away from the second extension 3, and the first connector 9 and the second connector 10 are connected by a telescopic member 11. During the sewing process, the telescopic member 11 can reduce the vibration of the sewing, improve the stability of the sewing, and ensure the quality of the zipper sewing.

[0041] In some embodiments, the non-exposed zipper sewing aid further includes a second support member 13. One side of the second support member 13 is connected to the first extension 2, and the other side is connected to the second extension 3. Along a first direction, a first limiting member 5 is located between the second support member 13 and the second limiting member 6.

[0042] By connecting the first extension 2 and the second extension 3 to both sides of the second support member 13, the first extension 2 and the second extension 3 can be supported by the second support member 13, reducing the risk of deformation between the first extension 2 and the second extension 3.

[0043] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0044] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims, and the specification and drawings can be used to interpret the content of the claims.
