[0023] See Figure 1-4The utility model provides a connecting base that can be used for the hemming device of a sewing machine, comprising a base carrier plate 1, wherein the upper end surface of the base carrier plate 1 is provided with a plurality of connecting grooves 11 with outward openings at the edge thereof, and connecting holes, wherein the connecting holes are provided on the base carrier plate 1 and are located on one side of the connecting grooves 11, and include a first connecting hole 12 and a second connecting hole 13; a transition connecting plate 2, wherein one end of the transition connecting plate 2 is detachably connected to the first connecting hole 12 or the second connecting hole 13, and a connecting carrier plate. When in use, the base carrier plate 1 is mounted on the machine platform of the sewing machine near the sewing needle, and a common fastening bolt is used to pass through the provided connecting groove 11 to achieve the purpose of fixed connection. The formed connecting groove 11 can be set as a vertical connecting groove 11, or as a horizontal connecting groove 10, so as to achieve multi-directional connection to the machine platform of different sewing needles. When the base carrier plate 1 is installed on the machine table near the sewing needle of the sewing machine, the connecting transition groove 20 and the connecting hole provided on the transition connecting plate 2 can be connected to each other with the connecting hole by fastening bolts and fixed to the base carrier plate 1; the formed connecting holes, the first connecting hole 12 and the second connecting hole 13, are suitable for double-needle sewing machines, improving the connection flexibility between the hemming device 5 and the sewing needle. The other end of the transition connecting plate 2 is provided with a connecting shaft for rotational connection to achieve a coordinated rotational connection of the connecting carrier plate. The connecting carrier plates used include two sets of first connecting carrier plates 3 and second connecting carrier plates 4 of different lengths, both of which have multiple sets of positioning holes 30 provided on their upper end surfaces, and the length of the first connecting carrier plate 3 is smaller than that of the second connecting carrier plate 4. The length difference between the first connecting carrier plate 3 and the second connecting carrier plate 4 facilitates the adjustment of the distance between the hemming portion relative to the sewing machine head when the hemming device 5 is installed. The first connecting carrier plate 3 or the second connecting carrier plate 4 is directly connected to the hemming connection part 52 to form a corresponding connecting hole 502 and the positioning hole 30 is fixedly connected by a fixing screw. The hemming base 50 ensures the processing stability of the entire hemming device 5. The fabric that needs to be hemmed enters the hemming pouring part 503 into the hemming curling part 53 and enters the hemming processing part to achieve the purpose of hemming processing.

[0024] Specifically, a raised stopper plate 22 is provided on the upper end surface of the transition plate 2 and the connecting hole. A clearance notch 202 is formed on one end of the upper end surface of the stopper plate 22. The connecting carrier plate has a rotational motion trajectory relative to the connected transition plate 2. To prevent 360° rotation around the connected transition plate 2, the raised stopper plate 22 serves as a limiting member. Furthermore, the clearance notch 202 provides a place for the connecting carrier plate to rotate to this point.

[0025] Specifically, a scale mark 14 is provided on the upper end surface of the base carrier plate 1 and at the lower edge.

[0026] 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.
