The pin hole of described needle plate is long to be 3.8mm～4.2mm, and wide is 3～3.2mm, the wide 1.8～2.2mm of crossed beam trunking, and dark 0.7～1.0mm, its length and width of locating piece are 3.2～3.6mm, and rotating shuttle is crossed the line position and is made as large space.

Operation principle: the utility model rotating shuttle colludes line, and knife needle and rotating shuttle constitute 1/2 rotating speed, and knife needle moves up and down once, and rotating shuttle takes two turns, and rotating shuttle colludes line and once constitutes lock-type chain stitch.

Beneficial effect

The utility model is reasonable in design, whole rotating shuttle is crossed space, line position and is increased, can normally use 2000D/3 upper thread and middle coarse wool line, the upper thread that thick line mechanism after the improvement uses is than thick 28 times of the original upper thread diameter that uses, and is applicable to that jeans, national costume, pure wool goods, leather, skin, case and bag do rough dress ornament stitching operation.Specify: knife needle adopts the knife needle principle, be difficult for stabbing cloth, and needle tip cooperates with shuttle better, one side top, needlework hole and other side-lower on the knife needle are designed to R shape respectively, pin hole on the needle plate is for ellipse and be provided with a crossed beam trunking, a crossed beam trunking is established in the presser feet baseplane, ensures that rotating shuttle is required easily to pass through with the line amount; Rotating shuttle adopts big capacity rotating shuttle shell, crosses the line place and relaxes, and interior bowl adopts bowl in the low capacity, and its back of the body finishing is wide, and locating slot adopts makes groove, and installing with locating piece increases the space, and thick line is passed through smoothly; Location hook is provided with locating piece, realizes locating the effect of protecting line; Make spring leaf in the shuttle, making has certain resistance in the peg or spindle, and peg or spindle can not irregular activity, and the bottom line of output is more even, and stitching is more attractive in appearance.
