[0011] By adopting the above technical solution, the pressing plate can be lifted up by the lifting component, thereby facilitating the shoe material to enter the shoe material channel, and the elastic reset component can drive the pressing plate to reset, thereby pressing the shoe material and making sewing more stable.

[0012] The utility model is further configured as follows: the lifting assembly comprises a seesaw plate arranged on the assembly frame and an articulated seat for the seesaw plate to be rotatably articulated.

[0013] By adopting the above technical solution, the pressing plate can be directly or indirectly pushed by rotating the seesaw. Since the elastic reset component has elastic avoidance space, the pressing plate can be lifted up. The hinged seat can facilitate the installation of the seesaw and form a fulcrum.

[0014] The utility model is further configured as follows: the elastic reset component includes a spring frame arranged on the assembly frame, a clamping rod for clamping the pressure plate, a spring sleeved outside the clamping rod, and a bolt threadedly matched with the spring frame; the clamping rod is guided and slidable on the spring frame, one end of the spring abuts against the clamping rod, and the other end abuts against the bolt.

[0015] By adopting the above technical solution, the compression amount of the spring can be adjusted by the bolt, thereby adjusting the clamping force of the clamping rod.

[0016] The utility model is further configured as follows: a relief cavity for accommodating wrinkles is provided at the bottom of the presser foot plate, located at the rear side of the oblique teeth.

[0017] By adopting the above technical solution, the bottom of the presser foot can be prevented from squeezing wrinkles and deforming, and the effect is better.

[0018] A further configuration of the utility model is that the helical teeth are arranged in multiple groups side by side and are arranged obliquely backwards.

[0019] By adopting the above technical solution, the effect is better when hooking and pulling the decorative strip, and slipping is avoided.

[0020] A further configuration of the utility model is that the needle drop hole penetrates the oblique teeth.

[0021] By adopting the technical solution, the root of the fold can be easily sewn on the shoe material. BRIEF DESCRIPTION OF THE DRAWINGS
