Claims

[Scope of utility model registration request]

(1) A frame formed in a U-shape, and a rear and front part that is parallel to the back member that forms the back side of the U-shape of the frame and supported by both side members that form both sides. Consisting of two shafts, hollow rear and front rollers rotatably supported via bearings on the rear and front shafts, respectively, and a device to prevent the cable from digging between the front and rear rollers, etc. is,
One end of the front shaft is rotatable about the one end within a plane that includes the axis of the front and rear shafts, and rotates at least about a line that passes near the one end and intersects the axis of the rear shaft at right angles. The front roller is rotatably supported as a shaft, and the other end is provided with a pin that can be freely retracted and retracted from a side member on that side of the frame, thereby making it possible to hold the front roller in a predetermined position and to rotate both of the above. A cable extension support device characterized in that it is configured to.

(2) The cable extension support device according to claim 1, wherein the bearings for supporting the front and rear rollers on the front and rear shafts are either ball bearings or roller bearings.

(3) A flange in which a device for preventing cables from digging in from behind is provided at both ends of the front and rear rollers so as to be close to each other;
and a utility model according to claim 1 or 2, which comprises at least a flange of anti-biting fittings formed along the circumferences of both ends of the front and rear rollers attached to the frames on both sides. Cable extension support device.

(4) The pin for holding the front roller in a predetermined position and rotating it is a U-shaped pin that is provided through the frame in a direction perpendicular to the front and rear axes, and one side is longer than the other. A spring is installed between the long side tip and the frame to constantly move the pin toward the tip side, and when the pin is pulled toward the rear end, the tip of the front shaft moves from the short side of the pin. The cable extension support device according to any one of claims 1 to 3, which is configured to be detachable.
