Problems solved by technology

[0002] As we all know, when trimming the thread of the lockstitch sewing machine, because the stitch length cannot be adjusted, the bottom thread end of a stitch length cannot form self-locking, and there are two thread ends, one long and one short, in the trimming of the sewing material, and the two thread ends are aligned. Long and short, one front and one back, resulting in the thread ends left after thread trimming are not firm, and will fall off with a slight pull, affecting the sewing effect
In addition, the thread is too long, which affects the aesthetic feeling

[0050] First, if the instructions are attached figure 2 Attached Figure 7 As shown, the limit rod 5 is similar to a chevron with low ends and a high middle. A tie rod hinge hole 53 is provided at the left end of the limit rod 5, and the tie rod hinge hole 53 and the tight seam tie rod 14 are hinged with the pin at the left end 16. Realize the rotation of the limit rod 5 relative to the tight seam tie rod 14; the middle high point of the limit rod 5 is provided with a fixed-axis hinge hole 52, and the fixed-axis hinge hole 52 is hinged with the fixed shaft 3 in a fixed position through the intermediate pin to realize the limit The rotation of the position rod 5 relative to the fixed axis 3; the right end of the limit rod 5 has an insert end 51, which is in the shape of an upper half arc, and is used to insert and insert between the connecting portion 4 and the buffer portion 6 from above .

[0051] In order to achieve the fixed position of the fixed axis 3, a limit rod bracket 1...

Abstract

The invention discloses a sewing machine. The sewing machine comprises a backstitch driving part and a backstitch executing mechanism connected with the backstitch driving part and used for realizing the backstitch sewing, and further comprises a tiny stitch executing mechanism connected with a tiny stitch driving part, elastically installed between the backstitch driving part and the backstitch executing mechanism and used for limiting the driving distance of the backstitch driving part. The sewing machine is capable of realizing the tiny stitch function by inserting and embedding the tiny stitch driving part between the backstitch driving part and the backstitch executing mechanism.

Description

Technical field [0001] The invention relates to the technical field of sewing machines, in particular to a sewing machine. Background technique [0002] As we all know, when the sewing machine is trimming, because the stitch length cannot be adjusted, the bottom thread of one stitch length cannot form a self-locking. When the sewing material is trimmed, there are two thread ends, one long and one short. Long and short, one after the other, the thread end left after trimming is not firm, and it will fall off with a gentle pull, which will affect the sewing effect. In addition, the thread is too long, which affects the beauty. [0003] Specifically, in order to realize the close seam operation, the close seam electromagnet is usually used to energize, and then the corresponding parts are driven to realize the movement of the oscillating seat to a very small stitch pitch, thereby completing the close seam function. Summary of the invention [0004] The object of the present invention...
