る。(Prior Art) FIG. 4 is an explanatory view showing a conventional cable pulling tool.
This is a set of two bundled metal wires (1),
The tension wires (4), (4 ') are formed by passing through the holes of the resinous ring body (7) from an appropriate length, and further the respective wires (1) emerging from the ring body (7) intersect each other. To form a strip-shaped net body (2) in an expanded state, and further, the tensile portion (4),
A hooking ring (5) is provided at each tip of (4 '), and a splicing wire (8) which is successively passed through the meshes on both sides of the mesh body (2) is spliced to one pulling part (4). It has a structure extending from the tip. When this is used, first, the end of the cable (9) is placed on the net (2), and the ring (7) is adjusted to the outer diameter of the cable (9) to confirm that there is no play. Next, a towel or the like is wound around the cable (9) to protect the cable (9) from being scratched by the mesh (2), and then the mesh (2) is covered with the cable (9) to form meshes on both sides. The mesh body (2) is formed into a tubular shape by joining the pieces together with the joining wire (8). Then, the splicing wire (8)
The attachment work of the cable pulling tool is completed by winding the end side of the mesh body (2) formed into a cylindrical shape by wrapping it around once and binding it. Then, by hooking a hook (not shown) on the hanging ring (5) and pulling it with a winch or the like, the outer diameter of the mesh body (2) is contracted, and the wire (1) does not bite into the cable (9) and does not come off. Withdraw 9). After the cable (9) is pulled out and given a slack for facilitating connection, the wound joint wire (8) is unwound and the joint wire (8) is removed along the mesh, Further, the cable (9) is removed from the net body (2) and the towel wound for protection is also removed. There are various other things, but in particular, the actual development of Sho 1958 3719
The construction of No. 135013 in 1960 is that one end of a cylindrical net body is closed and a hook is provided at the tip of the net body. When using this, the net body must be contracted. Increase the diameter and insert it into the cable. Then, extend the net to make it approximately the same diameter as the cable, cover the end of the cable with the net, hook the hook on the hook and pull it with a winch, etc. to reduce the outer diameter of the net. It is pulled.

影響を与える恐れがあった。(Problems to be solved by the invention) When this conventional product is used to prepare for the pulling work, the resin ring body (7) has a certain degree of hardness.
Affects the tightness of the net (2), and as a result, the net (2)
Was likely to partially bite into the coating of the cable (9), the coating might be damaged, and an accident in which the cable (9) fell out of the mesh body (2) was also likely to occur. Therefore, as a means for protecting the cable (9), it is necessary to pay sufficient attention so that the towel may be wound evenly, and the tubular net (2) is joined by the joining wire (8). In order to achieve this, it was necessary to pass through many meshes one by one, and it was extremely laborious and experiential. Therefore, there is a problem in that the work of attaching the conventional cable pulling tool is troublesome and takes time. In addition, when using the above-mentioned No. 3719/1983 and No. 135013/1985, and pulling the end of the cable, a part of the net is easily bited into the end face of the cable,
If the tightening condition is not uniform, there will be some places where the entire mesh does not adhere to the cable, and the cable will easily come off. Furthermore, if the cable or wire is used with oil adhered to it, the cable may be very easily pulled out, and the cable characteristics may be adversely affected.

本考案はケーブル（９）の把持が確実でしかも引張具の
取付け作業が簡単で短時間に出来るケーブル用引張具を
提供するにある。An object of the present invention is to provide a pulling tool for a cable (9) in which the gripping of the cable (9) is reliable, the attaching work of the pulling tool is simple, and the work time is short.

The part is formed with a substantially fan-shaped tension part that curves inward and becomes thinner toward the tip,
A hook is provided at the tip of the pulling portion, and an opening is provided at the peripheral edge of the pulling portion so that the wire has a slack.

とが出来るのである［第２図（ｅ）参照］。(Operation) Next, the operation of the present invention will be described. The net body (2) is contracted in advance to increase the diameter [see FIG. 2 (a)].
First, the cable (9) is inserted from the end of the mesh body (2) on the side opposite to the pulling part (4), and an appropriate length is opened (3).
[See FIG. 2 (b)]. Next, the mesh body (2) is contacted with the outer shape of the cable (9) and covered with the mesh body (2) by simply extending the mesh body (2) in the direction of the arrow in the figure, that is, in the middle side of the cable (9). See FIG. 2 (c)]. Then, the hook (not shown) is hooked on the hanging ring (5) and is pulled by a winch or the like to reduce the outer diameter of the net (2). At this time, since the wire (1) has a slack at the periphery of the pulling part (4), the ring (7) does not get in the way as in the conventional case, and the wire (1) is not a bite, and the wire (1) is a cable. The cable (9) is evenly adhered to the cable (9) so that the cable (9) can be reliably pulled out [see FIG. 2 (d)]. Also, since the opening (3) of the present invention is located closer to the center than the end of the cable (9), the mesh body (2) as in the conventional case does not strongly dig into the end surface of the cable (9), which makes it difficult to pull out. . After allowing the slack, remove the hook from the hook (5). Since the diameter of the net (2) is increased by contracting the net (2), the net (2) can be removed from the cable (9) very easily and in a short time [see FIG. 2 (e)]. ].
