[Problems to be solved by the device]

 Therefore, even if you try to pull by pulling on the part near the tip of the cable you are trying to wire, the cable slips out and comes out, it is difficult to pull it to your hand simply by changing the posture in the pulling direction, It is difficult to pull cables with small diameters such as telephone wires, and it is extremely difficult to pull cables that have come off and changed their postures in the posture along the pulling direction to pull them to your hand. It had the problem of being extremely bad. Therefore, there is a problem that it is difficult to pull the cable to the hand unless the tip portion of the cable to be wired is previously connected to form a loop and the loop portion is searched and hooked.

Further, in the known latter, as a means for solving such a problem, a U-shaped wire holding metal fitting having a large number of ring-shaped prongs attached to the lower side is formed and wiring is attempted. In this case, the clamping metal fitting is attached to the tip of the cable in advance, and the ring-shaped gusset of the clamping metal fitting is hooked with a hooking tool.In this case as well, the clamping metal fitting is attached to the tip of the cable to be wired. It had to be installed in advance, which required preliminary work.

A first object of the present invention is to solve the problem of such a conventional cable hook, and to form a loop by connecting the tip end portion of the cable to be wired in advance. The purpose of the present invention is to obtain a cable hook that can pull cables in a normal state without the need for preliminary work such as preliminarily attaching a holding metal fitting to which a ring-shaped tex is attached. .

A second object of the present invention is to facilitate wiring even if the cable to be wired is a small diameter cable such as a telephone line, as in the case of a relatively thick cable such as a three-phase electric wire. It seeks to obtain a cable hanger that can be pulled. The third purpose is to make such a cable hook into a simple structure without making the structure complicated and easy to use, and to efficiently manufacture it. It is to provide a cable hanger capable of

[0008]

[Operation] Since the cable hanging device of the present invention has the above-mentioned structure, the cable hanging device is attached to the distal end side of the operating rod (A) and is intended to be pulled at a work site such as an overhead ceiling. When (K) is hooked and pulled by the free end (2d) of the hook-shaped hanger body (2), the cable (K) pulls due to its own weight and the friction resistance with the floor. Against this, it moves into the space (S) between the rotating body (3) and the rising part (2b) of the hanger body (2), and then by the rotation of the rotating body (3) due to friction. It is fed into the inner part of the gap (S), that is, the upper narrowed part, and is sandwiched between the rotating body (3) and the upper end part of the hanging tool body (2). Therefore, it is possible to easily pull up to the hand while maintaining this sandwiched state. Therefore, it is possible to easily pull the cable under normal conditions without the need for preliminary work such as connecting the tip of the cable in advance to form a loop or attaching other metal fittings. .
