Hereinafter, embodiments of the present invention will be described with reference to the illustrated embodiments.

In the embodiment shown in FIGS. 1 to 3, reference numeral 1 denotes a bobbin shaft having a threading groove 2 in the axial direction, which is provided integrally with a rotating body 3 which rotates around the bobbin shaft 1. A thread fixing portion 4 for fixing one end of a thread 10 to be ligated is provided on a rotation outer peripheral portion of the rotating body 3 on the side of the bobbin shaft 1. The rotating body 3 is movably and rotatably provided on a guide bar 5 provided along the axial direction of the bobbin shaft 1. The rotating body 3 may be configured to be rotatably or rotatably supported on a bearing member provided on the guide bar 5 so as to be movable or movable along the axial direction of the bobbin 1. is there.

In the above description, the rotator 3 is movable on the guide bar 5 when, for example, the rotator 3 is restricted from moving by a stopper or the like when the rotator 3 is rotating. The term “rotatable” means, for example, that the rotation is restricted when moving, the number of rotations is stopped by the click mechanism when rotating, or the rotation is restricted so that it does not rotate more than three times. ing.

At the distal end of the guide bar 5, there is provided a backing plate 6 for opening and closing the distal end of the bobbin shaft 1.In the illustrated embodiment, the rotating body 3 is rotated as shown in FIG. When rotating the operation shaft 7, press the tip of the bobbin shaft 1 against the backing plate 6 and rotate the rotating body 3 so that the front end of the bobbin shaft 1 does not separate from the backing plate 6. The yarn 10 is configured to be securely wound around the yarn winding shaft 1.

As shown in FIG. 2, the rotating body 3 is rotated a required number of times, and the thread 10 is wound around the threading groove 2 one to three or four times, and then, for example, a ligature 1 2 With the needle 11 after sewing, the thread 10 is sunk from the tip of the threading groove 2 from the rotating body 3 side to the backing plate 6 side, and the rotating body 3 is rotated as shown in FIG. Together with the bobbin shaft 1 in the direction away from the backing plate portion 6 to remove the yarn 10 from the open end of the bobbin shaft 1, the end between the one end 4 of the yarn 10 and the free end 11 The first thread that ties the ligature 12 to the ligature 12;

Next, the rotating body 3 is reversed, and the thread 10 is similarly moved over the threading groove 2. After passing through the thread 1 to 3 or 4 times, the thread 10 is passed through the threading groove 2 with the needle 11 from the rotating body 3 side toward the backing plate section 6 side, and the thread winding shaft 1 is moved together with the rotating body 3. Is moved in the direction away from the backing plate portion 6 and the thread 10 is removed from the thread winding shaft 1, and the ligature 12 is tied between the one end 4 and the free end 11 of the thread 10. The knot of the eye will be formed by the main knot. By repeating this, multiple knots can be surely made. Note that if the rotator 3 is rotated in the same direction as the previous time to make a knot, it will be a reverse knot.

In the embodiment shown in FIGS. 4 and 5, the bobbin shaft 1 is provided so as to be able to be pulled out of the rotating body 3 in the direction of retracting in the direction of the rotating body. Therefore, as shown in FIG. 4, after the yarn is wound around the yarn winding shaft 1 and the leading end of the yarn 10 is sunk into the threading groove 2, the rotating body 3 is moved without moving the rotating body 3. If only the thread is pulled out into the rotating body 3 along the bearing hole 8, the wound thread 10 comes off the thread winding shaft 1 as shown in FIG. 5, and the knot 20 is completed.

In the case of the embodiment shown in FIG. 6, the bearing plate 9 is provided with a bearing hole 9 so that the thread winding shaft 1 can be pulled out through the patch plate 6 so that the winding thread is removed to form a knot.
