[0055] Example 2

[0056] According to the appendix Figure 1-4As shown, it includes a frame unit 1, on which a pedal adjustment unit 2 is provided;

[0057] The pedal adjustment unit 2 includes:

[0058] Driver component 21;

[0059] The movable rod 22 is connected to the drive assembly 21;

[0060] The pedal body 23 is tilted, and the bottom of the pedal body 23 is rotatably connected to the moving rod 22. The drive assembly 21 is used to adjust the position of the pedal body 23 to accommodate users with different leg lengths.

[0061] A connecting hose 24 is provided, one end of which is fixedly connected to the pedal body 23, and the other end of which is connected to the sewing machine.

[0062] The reset assembly 25 is disposed between the top end of the pedal body 23 and the extended end of the moving rod 22.

[0063] Furthermore, the driving component 21 includes:

[0064] Crank handle 211;

[0065] Rotating rod 212, the top end of rotating rod 212 is fixedly connected to crank handle 211;

[0066] The first bevel gear 213 is fixedly sleeved on the rotating rod 212;

[0067] The second bevel gear 214 is meshed with the first bevel gear 213.

[0068] Threaded rod 215, one end of which is fixedly connected to the second bevel gear 214;

[0069] A guide rod 216 is located on one side of the threaded rod 215. When the position of the pedal body 23 needs to be adjusted, the user turns the crank 211, which drives the rotating rod 212 to rotate. The first bevel gear 213 on the rotating rod 212 rotates accordingly. Since the first bevel gear 213 is meshed with the second bevel gear 214, the second bevel gear 214 also rotates, thereby driving the threaded rod 215 to rotate. A slider 221 on one side of the moving rod 22 is threadedly connected to the threaded rod 215. As the threaded rod 215 rotates, the slider 221 moves along the threaded rod 215, simultaneously driving the moving rod 22 to move. The slider 221 on the other side of the moving rod 22 is slidably connected to the guide rod 216, which serves as a guide to ensure the stability of the moving rod 22's movement. The movement of the moving rod 22 drives the pedal body 23 to move, thereby adjusting the position of the pedal body 23 to accommodate users with different leg lengths.

[0070] Furthermore, sliders 221 are fixedly connected to both sides of the movable rod 22, and the sliders 221 are slidably connected inside the bottom crossbar 11.

[0071] Furthermore, one slider 221 is threadedly connected to the threaded rod 215, and the other slider 221 is slidably connected to the guide rod 216.

[0072] Furthermore, the reset component 25 includes:

[0073] Sleeve seat 251 is fixedly connected to the extension end of the moving rod 22;

[0074] Slide rod 252 is slidably connected inside sleeve seat 251;

[0075] Spring 253 is sleeved on the outside of slide rod 252, with one end of spring 253 fixedly connected to sleeve seat 251 and the other end fixedly connected to pedal body 23. When the user presses down on pedal body 23, pedal body 23 rotates around the rotational connection point with moving rod 22, simultaneously compressing spring 253 in reset assembly 25. When the user releases pedal body 23, the elastic force of spring 253 causes pedal body 23 to return to its initial position, ensuring normal cyclic use of the pedal.

[0076] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
