で掴持する。A wire gripper 100 is attached to the left and right of the wire cutting tool with the insulating rod 30 interposed therebetween. As shown in Figure 1,
By pulling out the operation bolt 23, the space between the wire pressing member 26 and the wire receiving portion 222 of the support frame 22 is opened to the maximum extent. At this time, the upper and lower parts of the relay member 24 are not
Between the wire holding member 26 and the connecting end member 21, respectively.
It is preferable to provide a slight gap. Then, the grippers 100 at both left and right ends are hooked on the electric wire 6, and the operation bolt 23 of one (right side in this embodiment) of the gripper 100 is tightened, so that the electric wire 6 is separated by the electric wire receiving portion 222 and the electric wire pressing member 26. Hold on.

Not . Therefore, the connecting lever 25 uses the connecting pin 245 of the relay member 24 as a fulcrum, and the arrow 2 in FIG.
It slightly rotates counterclockwise as indicated by 51. In the position described above, the operation bolt 23 is tightened, and the electric wire 6 is sandwiched between the electric wire pressing member 26 and the electric wire receiving portion 222 of the support frame 22 ((B) of FIG. 4). At this time, the link mechanism 110 does not operate until the wire pressing member 26 contacts the wire 6. That is, the connecting end member 21 is protected from water by the insulating rod 30.
Since the horizontal movement is restricted, the link mechanism 110 is constructed.
The connecting lever 25 that is formed moves upwards as the relay member 24 moves.
It moves but does not rotate. This a tree, connecting lever 25
The connecting end member 21 is pulled up in the vertical direction.

Between the lower part and the wire holding member 26 and the connecting end member 21.
The wire holding member 26 while maintaining a slight gap generated in the
Compresses the wire coating, and the connecting lever 25
It is slightly rotated clockwise about the fulcrum 5 as indicated by an arrow 252. After the pressure with which the electric wire pressing member 26 compresses the electric wire 6 reaches a predetermined value, the above-mentioned gap disappears and the connecting lever 2
5 cannot rotate in the clockwise direction 252. Connection lever 2
5 is a watch indicated by an arrow 252 with the connecting pin 245 as a fulcrum.
When the connector end member 21 is slightly rotated in the direction,
Because it cannot move in the horizontal direction, the link mechanism 11
The support frame 22 connected to 0 is indicated by an arrow 61 (see FIG. 4).
(C)) Moves slightly in the horizontal direction. As a result,
The wire device 100 is at both ends of the insulating rod 30 while holding the electric wire 6.
Loosen the wire between the grippers. At this time, the gripper 10 on the right side
Similarly, 0 is pulled by the insulating rod 30 and the link mechanism 110 similarly strongly grips the electric wire 6.

Move, i.e. grabber
The electric wire on the outer side can be stretched, and relative sliding between the electric wire 6 and the gripper 100 and between the conductor of the electric wire 6 and the coating does not occur. Then, the electric wire can be easily separated between the grippers 100 on both ends of the insulating rod 30.
