During this period, the length of the locking edge can be adjusted by sliding the positioning plate 9 to move the positioning plate 9 in the slide rail 15. When the adjustment is completed, the operator pulls out the positioning plate 9. At this time, the No. 2 spring 22 at the top of the slider 11 outside the transmission tube 7 will drag the upper clamping plate 8 and make the upper clamping plate 8 move downward along the track inside the guide tube 10, thereby clamping the cloth, thereby completing the clamping operation on the top of the cloth.
[0020] Two groups of slide rails 15 are welded inside the conduit 10, and the slide rails 15 are slidably connected to the positioning plate 9; two connecting columns are welded on one side of the driving rod 6 close to the upper clamping plate 8, and the top end of the connecting column is welded to the lower clamping plate 13, and the lower clamping plate 13 is placed at the bottom of the upper clamping plate 8; a top cover 4 is installed on the top of the rectangular hole on the top side of the operating table 1, and a locking edge opening 3 is opened in the center of the top cover 4; the slide groove 18 and the top plate 14 are designed in a stepped manner, and the position of the top plate 14 is close to the outer wall of the transmission tube 7; when the clamping operation above the cloth is completed, the operator starts the motor 5, and the motor 5 drives the driving rod 6 to start rotating. At the same time, the limiting column 16 on one side of the driving rod 6 starts to move, and when the limiting column 16 contacts the slide groove 18, the limit column 16 is in contact with the slide groove 18. Under the pressing action, the lower limit column 16 will enter the No. 2 perforation 21, and the No. 2 perforation 21 will be blocked by the top plate 14. At this time, the position area of the transmission tube 7 is fixed, and the internal driving rod 6 continues to rotate. At this time, the driving rod 6 continues to rotate, thereby causing the lower clamping plate 13 at its center to begin to move to the bottom of the cloth, thereby completing the clamping operation on the lower part of the cloth; finally, the operator starts the sewing machine body 2 to sew and lock the edge of the cloth. When the locking edge is in contact, the driving rod 6 rotates half a circle, and the limit column 16 pops out from the other side of the top plate 14 under the action of the No. 1 spring 19, thereby driving the transmission tube 7 to continue to rotate, thereby completing the repeated operation; when use is finished or maintenance is required, the device can be taken out by opening the top cover 4 on the top of the operating table 1 for adjustment.
[0021] Working principle: when sewing and locking the edge of the cloth, the operator first passes the cloth through the gap between the upper clamping plate 8 and the positioning plate 9, and then passes the passed part through the gap between the bottom of the positioning plate 9 and the lower clamping plate 13. During this period, the positioning plate 9 can be slid to move the positioning plate 9 in the slide rail 15 to adjust the length of the locking edge. When the adjustment is completed, the operator pulls out the positioning plate 9. At this time, the No. 2 spring 22 at the top of the slider 11 outside the transmission tube 7 will drag the upper clamping plate 8 and move the upper clamping plate 8 downward along the trajectory inside the guide tube 10, thereby clamping the cloth, thereby completing the clamping operation on the top of the cloth; when the clamping operation on the top of the cloth is completed, the operator starts the motor 5, and the motor 5 drives the driving rod 6 to start rotating. At the same time, the limit column 16 on one side of the driving rod 6 starts to move. When the limit After the positioning post 16 contacts the slide groove 18, the limiting post 16 will enter the No. 2 perforation 21 under the pressing action of the slide groove 18, and the No. 2 perforation 21 will be blocked by the top plate 14. At this time, the position area of the transmission tube 7 is fixed, and the internal driving rod 6 continues to rotate. At this time, the driving rod 6 continues to rotate, thereby causing the lower clamping plate 13 at its center to begin to move to the bottom of the cloth, thereby completing the clamping operation on the lower part of the cloth; finally, the operator starts the sewing machine body 2 to sew the cloth and lock the edge. After the locking edge is contacted, the driving rod 6 rotates half a circle, and the limiting post 16 pops out from the other side of the top plate 14 under the action of the No. 1 spring 19, thereby driving the transmission tube 7 to continue to rotate, thereby completing the repeated operation; when use is finished or maintenance is required, the device can be taken out by opening the top cover 4 on the top of the operating table 1 for adjustment.
