It is lower to be known as " plane 20a1 ") from the axle center of pivot 30 towards the ridge W of the nearest movable handle part 20 in the axle center apart from pivot 30
Crest line extend rectilinear direction on, to the abutting part 22a of opposed fixation handle part 22 roll tiltedly substantially 3 degree (θ 1 of Fig. 2),
Such as 3.17 degree of inclination.Similarly, the plane formed by the crest line of multiple ridge W in the abutting part 22a of fixed handle part 22
(hereinafter referred to as " plane 22a1 ") is from the axle center of pivot 30 towards the prominent of the nearest fixation handle part 22 in the axle center apart from pivot 30
In the rectilinear direction that the crest line of W extends, the tiltedly substantially 3 degree (θ of Fig. 2 is rolled to the abutting part 20a of opposed movable handle part 20
2), for example, inclination 3.17 degree.As a result, as shown in figure 4, when abutting part 20a and 22a hold diameter or the handle with a thickness of 2mm~5mm
When holding object 84, the plane 22a1 in plane 20a1 and abutting part 22a on abutting part 20a is substantially parallel.Holding pair as a result,
As object 84 from abutting part 20a and 22a only by the pressure cancelled out each other, without by the length side of abutting part 20a and 22a
To mobile power.Thus, there is no diameter or with a thickness of 2mm~5mm holding object 84 to the inside of handle part 12 or outer
The worry that side falls off.
The crest line of the ridge W of fixed handle part 22 is opposed with the crest line of ridge W of movable handle part 20.Fixed handle part 22
Abutting part 22a in the vertex of ridge W and the vertex of the ridge W in the abutting part 20a of movable handle part 20 held fixed
When the abutting part 22a in portion 22 and the abutting part 20a of movable handle part 20 are closed, in the front end side with base portion 22d, 20d opposite side
It abuts against, and is separated with towards base portion 22d, 20d.In addition, as the abutting part 22a and movable handle part of fixed handle part 22
When 20 abutting part 20a holds electric wire 84, handle is come with interval similar in identical as the diameter of electric wire 84 or diameter with electric wire 84
Hold electric wire 84.
The interval (h1, h2 in Fig. 3) in the direction arranged side by side of the ridge W of abutting part 20a and 22a is 2mm.As a result, when
It connects livewire work holding tool 10 and holds diameter or the holding object 84 with a thickness of 2mm~5mm with abutting part 20a and 22a
When, there is no the worries that holding object 84 is damaged.That is, being supported in the case where above-mentioned interval is wider than 2mm with holding object 84
The ridge W connect is few, and the pressure from ridge W only acts on holding object 84 in tiny area.Therefore, pressure concentrates on handle
In the narrow regions for holding object 84, as a result, there are the worries that holding object 84 is damaged.For example, holding object 84 is
It is one in the ridge W that arbitrary abutting part side and electric wire abut against when the electric wire of diameter 2mm and above-mentioned are divided into 3mm, because
There are the worries that the cladding of electric wire is stripped or cuts off for this.If as a result, between ridge W between be divided into 2mm, even if hold object
Object 84 is the electric wire of diameter 2mm, is two in the ridge W that arbitrary abutting part side and electric wire abut against, therefore there is no electricity
The impaired worry of line.In contrast, in the case where above-mentioned interval is narrower than 2mm, there are being easy between ridge W by foreign matters from being blocked,
And the worry of the function of anti-sliding stop possessed by ridge W can not be played.In addition, above-mentioned interval is narrower, the quantity of ridge W is got over
More, the difficulty that will lead to processing increases.
As Fig. 3 the part (A), shown in the part (B), the side arranged side by side of multiple ridge W of abutting part 20a and 22a are set
To the not sharp wave mode of cross sectional shape, sinusoidal waveform.As a result, when abutting part 20a and 22a hold diameter or with a thickness of
When the holding object 84 of 2mm~5mm, there is no the worries that holding object 84 is damaged.That is, when the front end of ridge W is in point
When sharp shape, the pressure from ridge W only acts on holding object 84 in tiny area.Therefore, pressure concentrates on handle
In the narrow regions for holding object 84, as a result, there are the worries that holding object 84 is damaged.For example, working as holding object 84
When for electric wire, the front end of the sharp ridge of shape is stripped there are the cladding of electric wire or electric wire is cut-off worry.Phase therewith
Right, if the cross sectional shape in the direction arranged side by side of multiple ridge W is sinusoidal waveform, ridge W is applied to the pressure of holding object 84
Power dispersion, there is no the worries that holding object 84 is damaged.
As shown in figure 4, multiple ridge W that abutting part 20a and 22a is arranged in are set in the arranged side by side of above-mentioned multiple ridges
The position for being mutually butted the crest line of the front end of above-mentioned multiple ridges on direction.As a result, when abutting part 20a and 22a hold diameter
Or with a thickness of 2mm~5mm holding object 84 when, there is no holding object 84 be damaged worry.That is, even if in abutting part
Multiple ridge W of 20a and 22a are set to the feelings of the position of the crest line engagement of the front end on the direction arranged side by side of above-mentioned multiple ridges
Under condition, ridge W applies the pressure as shearing to holding object 84.In this case, the purpose of the present invention especially exists
In diameter can be held or with a thickness of the threadlike body, plate body or cloth-like body of 2mm~5mm, therefore this thin or thin holding pair
It is easy as object 84 exists by the worry sheared.In contrast, when each abutting part 20a and 22a setting makes above-mentioned multiple ridges
