[0020] 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 only 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.

[0021] See also Figure 1 to Figure 3In the embodiment of the utility model, a device for sewing the edge of a reversible quilt cover comprises a presser foot 1 installed on a sewing machine, one side of the presser foot 1 is fixedly connected with a fixed block 2, the fixed block 2 is sleeved with a plug-in mechanism through a latch 4, the plug-in mechanism is connected to one end of a top stop mechanism, and the top stop mechanism is used to support the flat seam position of the quilt cover; the plug-in mechanism is used to realize the quick connection or disassembly of the top stop mechanism and the presser foot 1; the end of the top stop mechanism is rotatably connected to a turntable 13, and the turntable 13 is used to reduce the friction between the quilt cover and the top stop mechanism, so as to facilitate the better movement of the quilt cover; the various parts of the top stop mechanism are fixedly connected through studs 8 and nuts 9.

[0022] In this embodiment: first, two pieces of fabric with different colors are flat-sewn to achieve the initial connection of the front and back quilt covers, and then a second sewing is required at the flat-seam position of the fabric to enhance the connection stability of the two pieces of fabric;

[0023] When performing secondary sewing, the limit column of the top stop mechanism is moved through the plug-in mechanism, and then the angle of the top stop mechanism is adjusted so that the turntable 13 is against the flat seam connection. At this time, one piece of cloth is located above the turntable 13, and the other piece of cloth is located below the turntable 13, and the second sewing can be performed. When sewing, the turntable 13 is used to press against the flat seam of the cloth to effectively position the cloth for making the quilt cover, thereby preventing deviation or uneven sewing lines during the secondary sewing process.

[0024] Please refer to Figure 3 The plug-in mechanism includes a plug-in column 11 which is integrally formed with the outer side of the fixed block 2. The outer wall of the plug-in column 11 is sleeved with a sleeve 3. Both the sleeve 3 and the plug-in column 11 have slots 12. The cross-sections of the outer wall of the plug-in column 11 and the inner wall of the sleeve 3 are both elliptical structures. The fully sleeve 3 is aligned with the slot 12 on the plug-in column 11 in the upper and lower directions, and the inner wall of the slot 12 in the aligned state is plugged with a pin 4.

[0025] In this embodiment: when installing the plug-in mechanism, first insert the sleeve 3 into the surface of the plug-in column 11. When the sleeve 3 and the plug-in column 11 are completely overlapped, the sleeve 3 and the slot 12 on the plug-in column 11 are completely aligned. At this time, the pin 4 can be inserted into the slot 12 to achieve the installation of the ejection mechanism. Conversely, the pin 4 can be pulled out of the slot 12 to complete the disassembly of the ejection mechanism.

[0026] Please refer to Figure 1 and Figure 2The top stop mechanism includes a connecting plate 5 fixedly connected to the outside of the sleeve 3, the connecting plate 5 is an "L"-shaped structure, and a slide groove 6 is provided on the horizontal plate portion of the connecting plate 5. The top stop mechanism also includes a No. 1 rotating plate 7, and the top two ends of the No. 1 rotating plate 7 are integrally formed with studs 8 protruding upward. One stud 8 is slidably connected to the slide groove 6, and the outer wall of the other stud 8 is rotatably connected to the No. 2 rotating plate 10. The outer wall of the stud 8 is threadedly connected to a nut 9. The two nuts 9 in a tightened state are used to limit the positions of the No. 1 rotating plate 7 and the No. 2 rotating plate 10.

[0027] In this embodiment: the nut 9 is then loosened, and the position of the No. 1 rotating plate 7 and the No. 2 rotating plate 10 can be adjusted. When the No. 2 rotating plate 10 drives the turntable 13 to be in the flat seam position, the nut 9 is rotated again. After the nut 9 is effectively tightened, the bottom of the nut 9 generates an effective clamping force to prevent the No. 1 rotating plate 7 and the No. 2 rotating plate 10 from moving, so that the turntable 13 can be kept in the current position.
