ようとするものである。 Conventional cord threading tools of this kind have a pair of rod-shaped swinging pieces that are integrated at the front end fulcrum and are gradually separated from each other toward the rear free end. By fitting the rings and sliding the sliding ring toward the free end side, the gripping claws formed at the free ends of both rocking pieces are forced into pressure contact, and the gripping claws are inserted between the gripping claws. There are some that are used by pinching the ends of the string. However, in the conventional product as mentioned above, the swinging lever is formed into a rod shape, so even if only the gripping claws are made wide, sufficient clamping force cannot be obtained by simply dispersing the clamping force. There was a problem that there was no.
Therefore, in all conventional products, the width of the gripping claws is 5 mm or less. Therefore, when using the conventional product for a relatively wide string, the string can only be gripped in a part of the width, making it extremely easy to come off, making it impossible to pull the string stably, and making it difficult to insert the string. It was not possible to do it smoothly. On the other hand, in order to provide a string threading tool that can securely hold a wide string, it is conceivable to form the swinging piece wide according to the width of the string, but according to the structure of the conventional product, If the movable piece is made wide, the sliding ring must also have a large diameter, which not only looks unsightly, but also causes problems such as being unable to insert it into the string passage or making it difficult to insert it. . The present invention aims to solve the above-mentioned problems and provide a string threading tool that can be conveniently used for inserting wide strings.

２間から紐Ａを取り外すことができる。 Hereinafter, the present invention will be explained in detail based on illustrated embodiments. The string threading tool of this embodiment is made by welding a pair of metal band-shaped plates having a predetermined width to each other at the front end, and by bending them at a slight angle in the direction of separation behind the welded part, so that they are integrated at a fulcrum A. Free end B
A pair of rocking pieces 1, 1 having an elastic restoring force are formed that gradually separate from each other toward. However, it is also possible to form the above-described structure by bending one strip plate at the center so that the center, that is, the bending point serves as a fulcrum for the swing pieces 1, 1. The two swinging pieces 1, 1 have their respective rear ends bent inwardly into a slight arc, and furthermore, serrated gripping claws 2, 2 are formed at the ends. Further, a pair of guide grooves 3, 3 are separately formed in the longitudinal direction at opposing positions of the swinging pieces 1, 1. Reference numeral 6 denotes a slider having a shaft portion 4 communicating the through grooves 3, 3, and large-diameter pushing heads 5, 5 formed at both ends thereof and slidingly contacting the outer surfaces of the rocking pieces 1, 1, respectively. It is slidably fitted into both of the through grooves 3, 3. The slider 6 has a length P obtained by subtracting the thickness of both the swinging pieces 1, 1 from the length of the shaft portion 4 when the gripping claws 2, 2 are in contact with the swinging pieces 1, 2. The head portions 5, 5 are each formed into a substantially hemispherical shape having a circular plane having a diameter slightly longer than the width of the through grooves 3, 3 at their base end surfaces. The method of using the above embodiment is to insert the end edge of the string A between the gripping claws 2, 2 of the swinging pieces 1, 1 which are in the expanded state as shown in FIGS. 1 and 2 when not in use. 3, by holding the heads 5, 5 of the sliders 6 located at the tips of the through grooves 3, 3 with your fingers and sliding them toward the rear end side of the through grooves 3, 3. As shown in the figure, the insertion operation is performed with the swinging pieces 1, 1 pressed in the abutting direction and the end edge of the string A being gripped between the gripping claws 2, 2. After the insertion operation, move the slider 6 through the groove 3, in the opposite direction as described above.
3, the swinging pieces 1, 1 return to the separated state in a V-shape in side view as shown in FIGS. 1 and 2 due to their own elastic restoring force. ，
The string A can be removed from between the two.

操作に好適に使用できるものである。 Since the present invention has the above-described configuration, it is possible to exert sufficient gripping force even if the width of the swinging pieces 1, 1 is made wide according to the width of the string, and the swinging With conventional products that have a sliding ring fitted around the outer periphery of the moving piece, a part of the outer periphery may be too large, making it difficult to insert the moving piece into the string passage part of clothing, etc. Even if the string is relatively wide, the end of the string can be gripped firmly over the entire width, and the string can be pulled stably without coming off easily, allowing for smooth and reliable insertion. . In addition, the operation of grasping the string is easy because it can be performed simply by sliding the sliders 6 fitted into the transparent grooves 3, 3 of the swinging pieces 1, 1, and the operation of inserting a relatively wide string is easy. It can be suitably used for.
