These terms are intended solely to facilitate the description of the present invention and simplify the description. They do not indicate or imply that the devices or components referred to must have a specific orientation, be constructed, or operate in a specific orientation. Therefore, they should not be construed as limiting the present invention. Furthermore, terms such as "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0026] In the description of the present invention, it should be noted that, unless otherwise expressly specified or limited, the terms "connected" and "connection" should be understood in a broad sense. For example, they can refer to fixed connection, detachable connection, or integral connection; mechanical connection, electrical connection; direct connection, or indirect connection through an intermediary. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on the specific circumstances.

[0027] Please refer to the accompanying drawings of the specification, the present invention provides a technical solution: Figures 1 to 3 As shown, a hemming auxiliary sewing tool includes a first body 10 and a second body 20, and a limiting hole 11 is provided on the first body 10; the second body 20 is arranged opposite to the first body 10, and a positioning pin 21 is provided on the second body 20, and the positioning pin 21 is arranged opposite to the limiting hole 11; the first body 10 has an abutting position with the second body 20, and a separation position separated from the second body 20; when the first body 10 and the second body 20 are located in the abutting position, the positioning pin 21 is located in the limiting hole 11, and the first body 10 and the second body 20 are surrounded by a limiting channel 30 for hemming feeding.

[0028] In this embodiment, the first body 10 and the second body 20 are fixedly assembled together by the cooperation of the limiting hole 11 and the positioning pin 21, and can be easily separated, which is convenient for adjusting the fabric during feeding and discharging during hemming, thereby improving work efficiency. At the same time, the limiting channel 30 constrains the shape of the feed and the folding state, solves the quality problem of uneven upper and lower pieces, and does not require finger pressing and holding, thereby reducing the probability of finger injury.

[0029] like Figure 2 and 3 As shown, preferably, the first main body 10 also includes an upper pressure plate 12, and the second main body 20 includes a bottom plate 24 and a vertical wall 22, the vertical wall 22 is arranged on the bottom plate 24, and the upper pressure plate 12 is arranged parallel to the bottom plate 24. When in the abutting position, the upper pressure plate 12 extends toward the vertical wall 22 and abuts against the upper part of the vertical wall 22.

[0030] like Figure 5 As shown, preferably, the first main body 10 is provided with a partition 13, and the partition 13 is arranged parallel to the bottom plate 24. The partition 13 extends toward the second main body 20, dividing part of the limiting channel 30 into a first limiting channel 31 and a second limiting channel 32, and a gap 33 is left between the partition end face 131 of the partition 13 away from one end of the first main body 10 and the second main body 20, and the first limiting channel 31 and the second limiting channel 32 are connected through the gap 33.

[0031] In this embodiment, the limiting channel 30 is transformed into a U-shaped channel by the partition 13, which further constrains the shape of the fabric during hemming feeding. There is no need for manual folding of the fabric during feeding, which improves work efficiency and further solves the problem of uneven upper and lower pieces.

[0032] like Figure 4As shown, preferably, the partition end surface 131 extends from the feed side to the discharge side and gradually approaches the first main body 10 , and the length of the isolation plate 13 is greater than that of the upper pressing plate 12 .

[0033] In this embodiment, the partition 13 is longer than the upper pressure plate 12, which can more conveniently adjust the folding state of the hem fabric when it enters the limiting channel 30, thereby improving the processing quality; the partition end face 131 extends from the feed side to the discharge side and gradually approaches the first main body 10, making it easier to feed the bottom of the hem fabric into the feed port.

[0034] like Figure 2 As shown, preferably, the bottom plate 24 is extended toward the feeding side, and a circular hole 241 is provided in the extended portion, through which screws pass to fix the bottom plate 24 on the sewing machine workbench.

[0035] In this embodiment, the presser foot is fixed to the front end by screws and is used in conjunction with a sewing machine to achieve the purpose of quickly sewing hems.

[0036] like Figure 2 and 4 As shown, preferably, a limiting structure is provided between the first body 10 and the second body 20 , and the limiting structure is used to limit the relative position of the first body 10 and the second body 20 .

[0037] Preferably, the limiting structure includes a first limiting boss 14 and a second limiting boss 23, the first limiting boss 14 is arranged below the first main body 10, and the second limiting boss 23 is arranged above the second main body 20. When in the abutment position, the first limiting boss 14 is arranged corresponding to the second limiting boss 23 to limit the relative position of the first main body 10 and the second main body 20 in the first direction; the positioning pin 21 includes a first positioning pin 211 and a second positioning pin 212, the first positioning pin 211 is arranged on the second limiting boss 23, and the second positioning pin 212 is arranged on the bottom plate 24.

[0038] like Figure 4 and 6 As shown, preferably, the end wall of the first limiting boss 14 close to the second main body 20 has a first step structure 141, and the end wall of the second limiting boss 23 close to the first main body 10 has a second step structure 231, and the first step structure 141 and the second step structure 231 are staggered to limit the relative positions of the first main body 10 and the second main body 20 in the second direction, and the first direction and the second direction are perpendicular to each other.

[0039] Preferably, the end wall of the first limiting boss 14 close to the second body 20 has a third step structure 142 to limit the relative position of the first body 10 and the second body 20 in a third direction, and the third direction, the second direction and the first direction are perpendicular to each other.

[0040] Preferably, the limiting structure also includes a fourth limiting boss 15, which is arranged below the first main body 10. When in the abutting position, the fourth limiting boss 15 is arranged corresponding to the bottom plate 24 to limit the relative position of the first main body 10 and the second main body 20 in the first direction; the end wall of the fourth limiting boss 15 close to the second main body 20 has a fourth step structure 151 to limit the relative position of the first main body 10 and the second main body 20 in a third direction, and the third direction, the second direction and the first direction are perpendicular to each other.

[0041] In this embodiment, the limiting structure makes the first body 10 and the second body 20 more stable when in contact, and prevents the first body 10 from moving in various directions relative to the second body 20 due to vibration of the sewing machine during operation.

[0042] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
