As a problem of the prior art, it is difficult to draw out the required number of wires when the fingers are used to divide the wires, because the binding wires are thin and the work gloves are used. When using the tip of a hacker tool, first explain the shape and function of the hacker tool.When viewed from the side, it bends to the left front from the middle part, and the tip further bends downward in a hook shape, The tip is conically pointed and a grip that rotates to the right rear of the middle part is provided.Hold the binding wire with the grip with the grip and turn it in a circle. Therefore, if you use the grip to apply force to the pointed tip, it will rotate as it rotates.Therefore, hold the shaft so that it does not rotate with your fingertips and separate it into several pieces. ing. There are too many binding points, and the above method makes it frustrating and tiring. Although an automatic electric binding machine is commercially available, it is expensive and weighs several kilograms and is not generally used.

[0004]

[Means for Solving the Problems] A horizontally long box-shaped mounting box is provided which is bent in a U-shape so that a bundle of binding wires can be housed therein. Is inserted and bent into a U shape, and the upper part of the bundled binding line is always in parallel with the upper surface in the mounting box so that the entire surface is in close contact with the upper surface side of the mounting box. , Providing a magnet having a size corresponding to the lateral width of the binding wire bent in a U shape, or as another method, a leaf spring as a pressing portion on the bottom surface in the mounting box,
It was formed in the shape of a mountain that bulges forward from the bottom surface of the rear part.

Further, as a device for hooking the binding wire accommodated in the mounting box, the operation section is, in plan view, orthogonal to the folded U-shaped central portion of the binding wire accommodated in the mounting box. A protruding push-out part that can apply a pushing force to the outer surface side above the mounting box when viewed from the side so that a long opening provided in the longitudinal direction of the mounting box in the longitudinal direction can be moved, and the lower front part. The inside of the mounting box is protruded, and a hooked portion with a curved shape is provided inside so that one or a few binding wires can be hooked at the protruding tip end, and the upper side of the mounting box is sandwiched between them. It was installed in the opening for long movement in the front and back. Further, the hook portion is adapted to project an appropriate length in front of the mounting box when the operation portion is moved forward.

The mounting box has a shape of a hollow square hole when viewed from the rear side, and can be mounted by inserting a binding wire that is folded and bent into a U shape from that portion. A gap that serves as a binding wire pull-out port corresponding to one binding wire or several wire lengths is provided in the lower part of the gap, and the binding wire to be hooked is inclined toward the lower right rear part. As a smooth output, the binding wire outlet has a horizontally long opening when viewed from the front.
The vertical width is determined by the number of binding wires to be drawn. According to the above configuration, when the binding wire is attached to the mounting box, the binding wire is always bundled in such a manner that the upper part of the binding wire is always in contact with the upper surface of the mounting box in parallel with the entire surface. Then, by moving the operation portion forward, a hooking portion provided so as to project on the upper surface in the mounting box can be hooked and brought out in front of the mounting box. Further, the operating portion may be provided with a spring on the rear side so as to automatically return when the finger is released, and the binding wire insertion port may be provided with a lid for preventing the binding wire from falling if necessary. .
