Description

  The present invention is a plug-in type detent used for adjusting the tension of a communication line or the like, that is, the insertion position of the metal line, when laying the communication line or the like using a metal line or the like retainer for holding the communication line. The present invention relates to a tool adjustment tool.

  Conventionally, a case having a conical surface through hole in the center, a pair of chucks mounted on the case and supporting the outer peripheral surface of a metal wire for retaining the inserted communication line, and the chuck of the case A coil spring that is fixed to one end of the through hole, a cap that is provided at the front end of the case and that is fixed to the case by crimping with the coil spring biased, and a cap that is provided at the rear end of the case to hold the communication line Wiring is performed using a communication wire plug-in type retainer including a pipe through which a part of the metal wire is inserted.

  When the communication line is retained by using such a communication line plug-type retainer, the plastic protective layer having a predetermined length at the tip of the metal line for retaining the communication line is removed, and the metal line is exposed. Then, this metal wire is inserted from the pipe and is held by a chuck (see Patent Document 1).

  When installing a communication line or the like using such a communication line retainer, when adjusting the tension of the metal line for securing the communication line, press the tip of the pipe with a tool such as a screwdriver to A method of adjusting the insertion position of the metal wire for loosening the chuck and holding the communication line is used.

Japanese Utility Model Publication No. 59-185922

  However, when adjusting the tension of the metal line to hold the communication line during wiring, adjust the insertion position of the metal line to hold the communication line by pressing the tip of the pipe with a tool such as the driver described above to loosen the tether. When using this method, it is difficult to adjust the insertion position of a metal wire or the like.

  Further, as described above, when the tip of the pipe is pushed in using a driver, there is a disadvantage that a coating layer such as a metal wire may be damaged.

  Therefore, the present invention has been made in consideration of such problems, and when performing the work of retaining the communication line, the insertion position of the metal wire for loosening the retainer and retaining the communication line is easily adjusted. An object of the present invention is to provide an adjustment tool for a plug-in type retractor that can be used.

  In order to solve the above-described problems, an adjustment tool for a plug-type retractor according to the present invention is provided at a case having a conical through hole therein, a chuck urged by a coil spring in the through hole, and a front end of the case. A cap that is fixed to the rear end of the case when pressed out of the case by the chuck, and a metal wire is inserted and fixed from the pipe through the chuck against the coil spring to hold the metal wire A holding position adjusting tool used for a plug-in type drawing tool, comprising a pair of gripping portions and a pinching portion, and an opening portion that allows a metal wire to enter one of the pinching portions but abuts the end face of the pipe A second holding means having a holding part for holding the cap is provided on the other of the holding parts, and the holding part is gripped in a state where the metal wire is inserted. By The end faces of the serial pipe presses against the coil spring force is one which allows adjusting the insertion position of the metal wire let loosen the chuck.

  For example, the first pinching means and the second pinching means are formed separately from the pinching portion and are attached to the pinching portion by rivets or the like. Further, by gripping the grip portion, the first sandwiching means and the second sandwiching means are opposed to each other within a predetermined range and move substantially in parallel. Further, the holding portion for holding the cap of the second pinching means is provided with a cut portion for avoiding the U-shaped fitting of the plug-in type retainer.

  The present invention includes a pair of gripping portions and a sandwiching portion, and one sandwiching portion is provided with a first sandwiching means that allows an entrance of a metal wire but has an opening that contacts the end surface of the pipe, A second holding means having a holding portion for holding a cap is provided on the other side of the holding portion, and when the work for holding a metal wire or the like for holding the communication line is performed, the gripping portion is inserted in a state where the metal wire is inserted. By gripping, the end face of the pipe is pressed against the coil spring force to loosen the chuck and adjust the insertion position of the metal wire.

  Thereby, when performing the operation | work which keeps a communication line, it becomes possible to adjust easily the insertion position of the metal wire for loosening a retainer and keeping a communication line.

  Since the first sandwiching means and the second sandwiching means are formed separately from the sandwiching portion, the first sandwiching means and the second sandwiching means are attached by using a commercially available sandwiching tool, so that the plug-in type retaining Fabrication of the tool adjustment tool is facilitated. Further, the first sandwiching means and the second sandwiching means can be stably fixed by being attached to the sandwiching portion by rivets or the like.

  Further, the first sandwiching means and the second sandwiching means grip the grip portion so that the first sandwiching means and the second sandwiching means are opposed to each other within a predetermined range and move substantially in parallel. Therefore, the pipe can be pushed in in the central axis direction.

  In addition, by providing a notch for avoiding the U-shaped bracket of the plug-in type retainer in the holding portion that holds the cap of the second pinching means, the direction parallel to or perpendicular to the U-shaped bracket of the communication retainer It can be inserted more and is easy to use.

  According to the present invention, when performing the work of securing the metal wire for securing the communication line, the insertion of the metal wire for securing the communication line by loosening the chuck of the tensioning tool using the adjustment tool for the plug-in type retention tool. The position can be easily adjusted.

  The first pinching means and the second pinching means can be easily produced by adjusting the first pinching means and the second pinching means using an existing pinching tool. Moreover, the 1st clamping means and the 2nd clamping means can be stably fixed by attaching to a clamping part with a rivet.

  Further, since the first sandwiching means and the second sandwiching means are opposed to each other within a predetermined range and move substantially in parallel, the pipe can be pushed in in the central axis direction.

  Moreover, it can be fitted from a direction parallel to or perpendicular to the U-shaped bracket of the communication retainer, and is easy to use.

  A best mode for carrying out an adjustment tool for a plug-type retractor according to the present invention will be described with reference to the drawings.
