[0027] See Figure 1-7The utility model discloses an adjustable auxiliary magnetic seat for a sewing machine, comprising a base body, the base body comprising a first base plate 6 and a second base plate 60, wherein the first base plate 6 and the second base plate 60 are in contact with each other to form a working groove 600 with an outward-facing through opening, and a blocking plate 7, the blocking plate 7 being disposed at one side opening of the working groove 600 and having a raised blocking portion 70 on an end surface facing the center of the working groove 600; an adjustment carrier 5 disposed at the other side opening of the working groove 600; an adjustment member 2 rotatably connected to an end surface of the adjustment carrier 5 away from the working groove 600, and having a magnetic piece 8 disposed on one end thereof within the working groove 600; and a connecting plate rotatably connected to the adjustment carrier 5 and located below the adjustment member 2. The first base plate 6 and the second base plate 60 are in contact with each other, forming a working groove 600 with an outward-facing through opening formed on the inner side thereof for accommodating the magnetic piece 8 providing magnetic force. The first and second base plates 6 and 60 are supported by iron materials, transmitting the magnetic force provided by the magnetic plate 8 to securely connect the entire base to the end surface of the sewing machine table. The barrier plate 7 can be made of a magnetic material such as copper or zinc alloy. Rotating the adjusting member 2 drives the magnetic plate 8, thereby making the entire base bottom magnetic or non-magnetic, facilitating control of the connection between the base and the end surface of the sewing machine table. Furthermore, a connecting plate is provided on the adjustable carrier plate 5 to facilitate connection to an external hemming device.

[0028] Specifically, the lower end surfaces of the first base plate 6 and the second base plate 60 form an inclined end surface 606 at the contact end surfaces. When the base contacts the end surface of the sewing machine worktable, a gap is formed between the inclined end surface 606 and the contact end surface, making it easier to remove the base body from the end surface of the sewing machine worktable.

[0029] Specifically, the protective shell 1 includes a protective inner cavity 12 with an outward opening on the lower end face of the protective shell 1. The outer end face of the protective shell 1 also includes a raised carrier plate 10 located at the opening of the protective inner cavity 12. The upper end face of the raised carrier plate 10 includes a raised connecting post 11, and the connecting plate is rotatably connected to the connecting post 11. The protective shell 1, with an opening on the inner side forming the protective inner cavity 12, covers the first base plate 6, the second base plate 60, and the adjustment carrier plate 5, providing protection. Furthermore, the outer end face includes an extended carrier plate 10 with a connecting post 11, which is used to connect with the connecting plate originally provided on the adjustment carrier plate 5, so that the connecting plate is provided on the outside and no longer connects to the adjustment carrier plate. A transition hole 13 is provided to facilitate the passage of the adjustment member 2. Furthermore, the connecting plates include a first connecting plate 3 and a second connecting plate 4. Both the first connecting plate 3 and the second connecting plate 4 have a through-hole 304, forming a length difference between the first connecting plate 3 and the second connecting plate 4. The connecting carrier plate used includes two sets of first connecting plates 3 and second connecting plates 4 of different lengths. Both upper end surfaces are provided with multiple sets of positioning holes 304. The length of the first connecting plate 3 is less than or greater than the length of the second connecting plate 4. The length difference between the first connecting plate 3 and the second connecting plate 4 facilitates adjustment of the spacing between the hemming portion and the sewing machine head when the hemming device 9 is installed. The first connecting plate 3 or the second connecting plate 4 is directly connected to the hemming connection portion 92, forming corresponding connecting holes 902 and positioning holes 304 that are fixedly connected via fixing screws. The hemming base 90 ensures the processing stability of the entire hemming device 9. The fabric to be hemmed enters the hemming processing portion from the hemming pouring portion 903 to the hemming curling portion 93, thereby achieving the purpose of hemming.

[0030] The above description is only a preferred embodiment of the present invention and does not limit the patent scope of the present invention. All equivalent structural transformations made by using the contents of the present invention specification and drawings under the utility model concept, or direct / indirect application in other related technical fields are included in the patent protection scope of the present invention.
