[0002] Traditional backpack straps are usually made of a single layer of material. When heavy objects are placed in the backpack, the backpack straps may put greater pressure on the shoulders and back. The design of single-layer folded-edge backpack straps can provide better load distribution and relieve pressure on the shoulders and back by folding a layer of material at the edge of the backpack strap, thereby improving the comfort of the backpack. However, single-layer folded-edge backpack straps cannot be processed in one step. The traditional method is to first manually press the folded edge of the fabric, and then stick the folded fabric to another piece of fabric. When sewing, the folded edge on one side is first sent to the bottom of the sewing machine needle for sewing, and then the folded edge on the other side is sewn. The steps are cumbersome, the folded edges are uneven during sewing, and the quality of the finished product depends on the level of the sewing master. Therefore, to address the above problems, a single-layer folded-edge module device is specially proposed. Utility Model Content

DETAILED DESCRIPTION
[0016] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0017] Refer to the instruction manual Figure 1-3 The single-layer folding module device includes a fixed connecting block 1, a straight inlet module 3 is welded and fixed on the surface of the fixed connecting block 1, a layered support 4 is welded and fixed on the top of the straight inlet module 3, a single-layer folding module body 5 is welded and fixed on the top of the layered support 4, and a nut connecting groove 2 is opened on the surface of the fixed connecting block 1; after the cloth strip enters from the inlet of the single-layer folding module body 5, the cloth strip is pushed, and the shape of the single-layer folding module body 5 is used to change the state of the cloth strip at the outlet to a folded state.
[0018] Then, the folding of the single-layer folding module body 5 is arranged in an arc shape, and the single-layer folding module body 5 is arranged in an inclined shape. The higher inclined part of the single-layer folding module body 5 is the folding inlet, and the lower inclined part of the single-layer folding module body 5 is the folding outlet. The cross-sectional diameter of the folding inlet of the single-layer folding module body 5 is larger than the cross-sectional diameter of the folding outlet of the single-layer folding module body 5. The folding outlet of the single-layer folding module body 5 is fitted with the straight outlet of the straight inlet module 3; through this mechanism, the cloth strip can be folded after entering from the inside of the single-layer folding module body 5.
[0019] Next, the four corners of the fixed connection block 1 are set to be rounded, and the inside of the nut connection groove 2 is elliptical; through this mechanism, the fixed connection block 1 will not scratch the user due to the sharp corners when moving, thereby improving the safety of the tool.
[0020] At this time, a placement groove 6 is provided on the upper end surface of the single-layer folding module body 5, and a first auxiliary block 7 is fixedly connected to the upper side of the placement groove 6.
