[About mounting on a rod]
The procedure for attaching the connector 100 to the rod-shaped body 6 will be described. FIG. 2 is mainly referred to for each component of the connector 100.

First, the connector 100 is assembled. First, the hook portion 18 of the first sandwiching member 1 is locked to the locking end portion 28 of the second sandwiching member 2. The bolt insertion holes 15 and 25 overlap their respective axes. Further, the connecting wire 3 hooks the first annular portion 31 on the second surrounding portion 12 (see FIGS. 3 and 5). Further, the washer 53 is arranged on the side of the bolt head 51a, and the screw portion 51b of the bolt 51 is inserted into the washer 53 and the coil spring 4. The small diameter side of the coil spring 4 is arranged so as to face the washer 53.

Then, the bolt head 51a of the bolt 51 is arranged on the side of the first sandwiching member 1, and the screw portion 51b of the bolt 51 inserted into the washer 53 and the coil spring 4 is inserted into the bolt insertion holes 15 and 25. A nut 52 is screwed into the screw portion 51b from the back side of the second sandwiching member 2. As a result, the first sandwiching member 1 and the second sandwiching member 2 are fastened. Further, the coil spring 4 is sandwiched between the seat portion 15a and the washer 53. When screwing the nut 52, by applying the nut 52 to the inside of the annular protrusion 26, the center of the screw hole of the nut 52 and the center of the bolt insertion hole 25 can be well aligned, and the screw can be screwed. Good workability during joint work (see FIGS. 4 and 5).

After fastening the first sandwiching member 1 and the second sandwiching member 2, as shown in FIG. 1, the linear portion 30 is wound around the channel 62 or the like by at least one turn. Then, the first annular portion 31, the first sandwiching member 1 and the second sandwiching member 2 connected thereto are inserted into the second annular portion 32 together with the linear portion 30. As a result, the connector 100 and the channel 62 are connected.

The bolt 51 and nut 52 are loosely tightened. At this time, as shown in FIG. 6, the rod-shaped body 6 is placed on the V-shaped receiving portion in the axial direction formed between the end surface of the corner portion 19a and the inclined surface portion 21a in the radial direction of the rod-shaped body 6. Apply to. When the rod-shaped body 6 is pushed in the radial direction as it is, the rod-shaped body 6 is guided by the end surface of the corner portion 19a and the inclined surface portion 21a, and begins to enter between the first main body portion 10 and the second main body portion 20. Then, the first main body 10 is pushed apart by the rod-shaped body 6 with respect to the second main body 20 while resisting the elastic urging force of the coil spring 4.

When the rod-shaped body 6 is further pushed in, the first surrounding portion 11 naturally surrounds the rod-shaped body 6, and in this state, the elastic restoring force of the coil spring 4 causes the first main body portion 10 and the second main body portion 20 to come into contact with each other. The rod-shaped body 6 is temporarily fixed in between. In this way, the rod-shaped body 6 can be easily temporarily fixed to the connector 100. Since the fastening member 5 is maintained in the fastened state at the time of this temporary fixing, for example, the nut 52 is not dropped and the mounting workability is good. Further, since the fastening member 5 is maintained in the fastened state at the time of this temporary fixing, the first annular portion 31 includes the screw portion 51b of the bolt 51, the first main body portion 10, the second main body portion 20, and the locking end. Since it is locked to the hook portion 18 locked to the portion 28, the connecting wire 3 does not fall out of the first main body portion 10 and falls, for example, the mounting workability is sufficient to work with one hand. good.

After that, by completing the fastening with the fastening member 5, the connector 100 can hold the rod-shaped body 6 in between. As a result, the connector 100 is fixed to the rod-shaped body 6. Further, the channel 62 is connected to the rod-shaped body 6 via the connector 100.

As described above, it is possible to provide a connecting tool having good mounting workability.
