In this embodiment, the vertical plate 209 is located above the horizontal plate 208, and the horizontal plate 208 and the vertical plate 209 constitute an L-shaped member. The installation position of the presser foot body 2 on the support base 1 is conveniently adjusted by providing the strip hole 210 on the vertical plate 209. The length direction of the elongated hole 210 may be in the horizontal direction or in the vertical direction. The elongated hole 210 is provided in the vertical direction in order to adjust the height position of the presser foot body 2 so that the cloth can smoothly pass below the presser foot body 2.
In some embodiments, referring to fig. 1, horizontal plate 208 and vertical plate 209 are integrally formed. In this embodiment, the presser foot body 2 is a sheet metal part. The flat plate is folded into an L shape along the folding line in a folding mode, and finally the horizontal plate 208 and the vertical plate 209 are obtained. Integrated into one piece's structure is compared in welded fixed mode, and structural strength is higher, and is durable more.
