[Prior art]

 FIG. 6 is a perspective view of a prior example of a threader for a sewing machine needle. The threading device 101 for a sewing machine needle according to the preceding example includes a guide member 102 having a groove formed at the tip thereof, and an operation for threading the thread A positioned in the groove with respect to the needle B similarly positioned. And a unit 103. The operation unit 103 is connected to a base of a rod (not shown) provided at the center of the guide member 102 so as to be able to advance and retreat.

The groove of the guide member 102 has a Y-shaped cross-section groove 104 for positioning the thread A in the horizontal position and a Y-shaped cross-section groove 104 which is close to the side of the sewing machine needle B which receives the vertical position of the sewing machine needle B. And a V-shaped cross-sectional groove 105 for positioning the thread A. A rod (not shown) forms a position facing the thread A on the side of the sewing needle B, and is provided so as to be able to advance and retreat in the longitudinal direction of the guide member 102. The guide member 102 is urged forward by a spring (not shown) built in an operation unit 103 provided at the base of the rod, and the urging force within this fixed range does not exert an excessive force on the sewing needle B without causing excessive force to the sewing needle B. B can be positioned.

After the V-shaped groove 105 of the guide member 102 is aligned with the sewing needle B from the direction of the threading hole C, the rod is advanced by the operating unit 103, and the thread A is attached to the side surface of the sewing needle B at the tip. Press. When the guide member 102 is moved along the sewing machine needle B in this state, the rod tip enters the threading hole together with the thread at a position facing the threading hole C. By pulling out the loop-shaped thread extruded from the opposite side of the threading hole by hand, the thread can be passed through the threading hole of the machine needle.

[0005]

However, since the threader 101 is restricted in its posture with respect to the sewing machine needle B in the vertical position and has no degree of freedom for stably holding the thread A, the Y-shape of the guide member 102 is cut off. When the yarn A is positioned in the surface groove 104, the terminal end of the yarn A may slide down from the Y-shaped groove 104. In this case, not only the threading cannot be performed but also the rod or the sewing machine needle B may be damaged by the pushing operation of the operation unit 103.

[0006] An object of the present invention is to provide a threading device for a sewing machine needle having a simple configuration that enables reliable threading by simple handling.

[Means for Solving the Problems]

 In order to solve the above-mentioned problem, a guide member having respective grooves for positioning the sewing machine needle and the thread with each other, and an advance / retreat for pressing the thread positioned in the groove of the guide member against the similarly positioned sewing needle. In a threader for a sewing machine needle including a possible rod, a holding means capable of detachably holding at least one side of the thread positioned in the groove of the guide member is provided.

[0008] The threader of the sewing machine needle has a holding means capable of detachably holding the side portion of the thread positioned in the groove of the guide member. Therefore, the sewing machine positioned in the groove of the guide member. Since the end portion of the yarn extending from the main body can be held by the holding means, the yarn is stably positioned without slipping off the groove of the guide member.

[0009] The holding means is formed by a thread hooking member separate from the guide member, and a threaded portion capable of holding the thread in a detachable manner with the thread hooking member, and a thread hooking member fitted and fixed to the outer periphery of the guide member. When the fitting portion is formed, a separate threading member which can be easily formed is attached to the guide member, so that the holding means can be formed in a threader of a general sewing needle.

If the indentation of the threading member is opened in both the upper and lower directions and is formed on both sides of the guide member, the threading device can be used without distinguishing between the upper and lower sides. .

In the case where an operating portion connected to the base of the rod for moving the rod forward and backward is provided so as to be able to advance and retreat with respect to the guide member, and a flat portion for preventing rolling is formed on a side surface of the operating portion. In addition, since the rolling and falling of the threader can be prevented and deformation due to the impact can be avoided, the accuracy of members required for threading can be secured.
