Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings and examples.

As shown in fig. 1 to 5, the sewing machine disclosed in this embodiment includes a pedal 1, two flexible bending portions 2 are symmetrically disposed on an upper plate surface of the pedal 1, the two flexible bending portions 2 respectively correspond to two feet of a user, and the flexible bending portions 2 are preferably made of leather, so that the sewing machine has better flexibility. An interval 3 is kept between each flexible bending part 2 and the plate surface of the pedal 1; one end fixed connection in the face of footboard 1 of flexible kink 2, the other end of flexible kink 2 extends has movable strip 4, and this movable strip 4 sets up with flexible kink 2 is integrative, also is made by the leather, consequently has the pliability of preferred. More specifically, a press roller assembly 5 pressed above the movable strip 4 is fixed on the upper plate surface of the pedal 1, and a limiting assembly 6 used for limiting the position of the movable strip 4 is arranged on one side of the press roller assembly 5 on the upper plate surface of the pedal 1.

Furthermore, the fixed end of the flexible bending part 2 is integrally connected with a fixed block 7, and the fixed block 7 is fixed on the upper plate surface of the pedal 1 through a fixing screw 8.
