[0008] Figure 2 It is a schematic view of the sewing machine presser foot structure of the utility model embodiment one;

[0009] Figure 3 It is a schematic view of the sewing machine presser foot structure of the utility model embodiment two. DETAILED DESCRIPTION

[0010] The utility model is further described below in combination with the drawings and examples.

[0011] See Figure 2 、 Figure 3 A sewing machine presser foot structure comprises a sewing machine presser foot body 1, a needle slot 2 is arranged on the sewing machine presser foot body 1, a thread pressing plate device 4 is arranged on at least one side of the end part 3 of the needle slot on the sewing machine presser foot body 1, and the sewing thread is pressed tightly through the thread pressing device, so that the sewing machine presser foot body stably presses the sewing thread, different sewing of stitches is adapted, the stability of the stitches is ensured, and the sewing efficiency and the sewing effect are effectively improved.

[0012] The thread pressing device 4 is a thread pressing plate 5 structure, preferably the thread pressing plate 5 is an inclined thread pressing plate 5-1, and the angle adjustment of the presser foot is realized through the adjustment of the presser bar; when the stitch changes, the distance between the needle bar and the end part of the needle slot on the sewing machine presser foot body is adjustable, so that the length of the sewing thread from the needle bar to the end part of the needle slot is adjustable, the sewing machine presser foot body stably presses the sewing thread, different sewing of stitches is adapted, the stability of the stitches is ensured, the sewing efficiency and the sewing effect are effectively improved, and different sewing of stitches is adapted.

[0013] The thread pressing plate 5 is arranged on the end part 3 of the needle slot, the thread pressing plate 5 is an inclined thread pressing plate 5-1, and preferably the inclined thread pressing plate 5-1 is arranged on the left side of the end part 3 of the needle slot on the sewing machine presser foot body 1; due to the movement track of the thread, the stability of the pressed sewing thread is further ensured.

[0014] 6 in the drawings is a drop needle position.

[0015] The sewing machine presser foot body 1 and the thread pressing plate 5 are integrally formed, the processing technology is reduced, and the production cost is reduced.

[0016] The thread pressing device can be arranged on the end part of the needle slot of the sewing machine presser foot body, or the thread pressing device can be arranged on both sides of the needle slot of the sewing machine presser foot body.

[0017] The utility model and its implementation mode are described above in a schematic manner, and the description is not restrictive, the drawings only show one of the implementation modes of the utility model, and the actual structure is not limited thereto, and the person skilled in the art is inspired thereby, without departing from the purpose of the utility model, as long as the thread containing groove is formed by the blocking surface between the inner shuttle track on the outer side of the opposite end of the drop needle hole of the inner shuttle body and the bottom of the rotating shuttle inner shuttle body, the similar structure mode and the example are not creatively designed, and all should belong to the protection range of the utility model.
