The specific embodiment
Below in conjunction with accompanying drawing the utility model is further described.
As Fig. 1, shown in Figure 2, a kind of use in sewing machine wire-clamping device described in the utility model comprises thread tension stud 8, and clamp axle 2, fixed cover are located at tension seat A1 and the tension seat B11 at thread tension stud 8 two ends, and said structure constitutes the utility model agent structure.
Particularly, described tension seat A1 is provided with locating hole 14, and tension seat A1 is fixed on the thread tension stud 8 by the set screw of being located in the locating hole 14 7; Described tension seat B11 is provided with locating hole 14, and tension seat B11 is fixed on the thread tension stud 8 by the set screw of being located in the locating hole 14 7.
Be provided with central through hole 15 in the described thread tension stud 8, described clamp axle 2 one ends stretch into central through hole 15 fixedlys connected with clamp pressing plate 4, and described clamp axle 2 other ends are provided with connector 6.Particularly, the center is provided with fixing hole 16 on the described clamp pressing plate 4, and described clamp axle 2 one ends pass fixing hole 16, and fixing by hold-down nut 5.
Be arranged with clamp 3 and following clamp 10 on the thread tension stud 8 between described tension seat A1 and the tension seat B11, described going up is provided with lead-in wire spring 9 between clamp 3 and the tension seat A1, and lead-in wire spring 9 one ends are located at clamp 3 and following clamp 10 1 sides.The outer end of described lead-in wire spring 9 preferably is provided with the V-type shape, is mainly used in guiding sewing thread, avoids it that bigger swing takes place.
