[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a grip for pulling a wire.

[0002]

[Prior art]

 When wiring electric wires, cables, etc. to pipes, etc., there is a case where the nominal line is first passed through, and then the nominal line is pulled by connecting the tip of the electric wire etc. to the nominal line. Conventionally, when pulling such a call line, the call line was grasped and pulled directly with a hand such as a gloved hand.

[0003]

[Problems to be solved by the device]

 However, since the nominal line is thin, it is difficult to apply force and the tightening force cannot be increased. In addition, in order to make it easier to pass the nominal wire through the pipes, etc., the outer peripheral surface of the nominal wire may be coated with a lubricating liquid such as water, oil, or a surfactant before entering the wire. In some cases. Therefore, even if an attempt is made to pull the nominal line, the hand slips along the nominal line, and it is not possible to pull it with a strong force, resulting in poor workability.

Therefore, an object of the present invention is to provide a wire pulling grip that solves the above-mentioned conventional problems.

As a result, the tensile force can be reliably transmitted to the nominal line, and the grip body does not slip along the nominal line.

(According to the third aspect) Since the grip body is made of the elastic body that can be bent and gripped, it is possible to hold the call line by directly grasping the thin call line with a gloved hand. Further, since the cross-sectional shape is V-shaped or U-shaped, the grip body is easy to grip and the nominal line is easily pinched. Moreover, when the nominal line is tightened, many small protrusions bite into the outer peripheral surface of the nominal line, so even if the outer peripheral surface of the nominal line is wet with lubricating liquid or sweat water, sufficient frictional resistance can be obtained and The tensile force can be reliably transmitted to the wire, and the grip body does not slip along the nominal line.

Since the grip body is made of an elastic body that can be bent and gripped (according to claim 4), it is possible to hold the fine call line by directly grasping the fine call line with a gloved hand. Also, when the nominal line is tightened, many small protrusions bite into the outer peripheral surface of the nominal line.Therefore, even if the outer peripheral surface of the nominal line is contaminated with lubricant or sweat water, sufficient frictional resistance can be obtained and the nominal line The tensile force can be reliably transmitted to the wire, and the grip body does not slip along the nominal line.

(According to the fifth aspect) In the sandwiching state of the nominal line, the small convex portion bites into the outer peripheral surface of the nominal line, so that the tensile force can be reliably transmitted to the nominal line.
