The invention relates to the technical field of sewing machines and particularly discloses a sewing machine presser foot applicable to sewing of a wire ring casing of a bar. The sewing machine presser foot is connected on a presser bar of a sewing machine and comprises a pressing block connected with the presser bar and used for applying pressure to the wire ring casing; a left pressing claw and a right pressing claw located on two sides of an end are arranged at one end of the pressing block; an arch-shaped limiting groove capable of wrapping half of the wire ring casing and performing a limiting function is formed in the bottom surface of the pressing block and located between the left pressing claw and the right pressing claw in the horizontal space. The sewing machine presser foot solves the problem that traditional planar presser feet cannot be well matched with a wire ring casing with an embedded core wire, accordingly, a sewing deviation phenomenon cannot occur to the sewn wire ring casing, and the production efficiency is improved.
