[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] This embodiment provides a sewing machine push plate mechanism, such as Figure 1-Figure 3 As shown, it includes a base plate 1 and a push plate assembly 2; the push plate assembly 2 includes a push plate bracket 2-1, a push plate 2-2 and a push plate spring 2-3; a buckle 2-1-1 is provided at one end of the push plate bracket 2-1, and when the push plate 2-2 is installed on the push plate bracket 2-1, the buckle 2-1-1 will firmly fix the push plate 2-2.

[0025] The push plate bracket 2-1 is U-shaped. Figure 4As shown, a buckle 2-1-1 is provided in the middle of its horizontal edge to achieve buckling with the push plate 2-2; inclined surfaces are provided on both sides of the horizontal edge, so that the bracket 2-2-1 is installed on the push plate bracket 2-1 along the inclined surface to play a guiding role; 7-shaped guide grooves 2-1-2 are provided on the inner walls of the two longitudinal edges, and waist-shaped holes 2-1-3 are provided on the inner sides of the longitudinal edges, respectively, and there are 2 waist-shaped holes on each side. The bottom plate 1 is connected to the push plate bracket 2-1 through the waist-shaped holes 2-1-3 and screws, and one end of the push plate spring 2-3 is fixed on the push plate bracket 2-1 on the inner side of the waist-shaped hole, and the other end cooperates with the slot on the push plate 2-2.
