で案内できず糸通しが困難となる欠点があつた。 Conventionally, as shown in FIG. 1, a sewing machine equipped with a cloth cutting knife that cuts a material to be sewn (not shown) along a seam line in conjunction with a needle bar that moves up and down, such as an overlock sewing machine M, has the following features: For its function, a cloth cutting knife 2 is disposed near the sewing machine needle 1. Therefore, when threading the thread 3 through the sewing machine needle 1, the fingertip 4 comes into contact with the cloth cutting knife 2 as shown in FIG. 2, and the third tip can be guided as close to the needle hole 1a of the sewing machine needle 1 as desired. The problem was that it was difficult to thread the thread.

This needle bar 13 has a U-shaped cross section and is provided via a first needle bar 13a and second needle bars 1 and 5 connected to the first needle bar 13a by a screw 14. It is composed of a body 16. Reference numeral 17 denotes a rectangular parallelepiped needle holder which is loosely fitted into the holder 16 constituting the needle bar 3, and is rotatably supported on the holder 16 by a shaft 18. A coiled spring S is loosely fitted onto this shaft 18, and the other end is fixed to the needle clamp body 17 and the holding body 16, and the needle clamp body 17 is always moved in the direction of arrow B in FIG. 3B. It is biased to rotate. Reference numeral 19 is an L-shaped spring stopper member provided along the outer periphery of the holding body 16, and has a protrusion 19a bent toward the opening 16a of the holding body 16 at one end, and is connected to the operator side. At the other end, there is a pressing part 19 bent outward of the holding body 16.
It has b.

9b causes one side to bend about the screw 19c as a fulcrum, thereby moving the protrusion 19a in the direction D in FIG. is moved from the state shown in Figure 3A to the state shown in Figure 3B.

次にこの針留めの作用を説明する。 Next, the function of this needle clamp will be explained.

9 by pointing the pressing part 19b (not shown) to the arrow C.
When pushed in this direction, the stopper member 19a also moves in the direction of arrow D, as shown in FIG. 6, against the spring force. As a result, until now the stopper member 19
The needle clasp 17, which was locked in the holder 16 by the protrusion 19a, is quickly rotated to the state shown in FIG. This allows threading to be carried out easily.

行うことができるという効果を奏する。 As described above, according to this invention, the needle can be easily moved from a position that coincides with the axis of the needle bar to a position that is separated from the axis by simply pressing the stopper member with the fingertip due to the force of the spring. This has the effect that the threading work can be easily performed and the needle can be placed in a position where the threading work can be easily performed with a simple operation.
