Claims

[Claims for Utility Model Registration] 1. Each roller 4, ₄ has a rotating shaft 5 parallel to the inner peripheral surface of the upper half main body 1 and the lower half main body 2. A wire extension roller for an underground cable, in which two rows of diagonally crossed parallel parts 6 are formed, and rollers 4, ₄₁ are arranged in two rows on the inner surface of the main body. 2 At the opening/closing end of the upper half main body 1, a sheath body 7 is fixed in the lateral direction, on which a threaded rod 9 with a male screw 8 carved into the inner tip and a grip 10 slidable slides on the other end. A wire extension roller for an underground wire is provided with a female screw hole 12 at the opening/closing end of the lower half main body 2 at a corresponding position into which the male screw 8 is screwed. 3. Each roller 4, 4 has a rotating shaft 5 parallel to the inner peripheral surface of the upper half body 1 and the lower half body 2. Parts of both end portions of the rollers 4, 4 ₁ are diagonally crossed in two rows in the line extension direction. The rollers 4, ₄₁ are arranged in two rows on the inner surface of the main body by forming cross-parallel parts 6, and a sheath body 7 on which a screw rod 9 slides is fixed at the opening/closing end of the upper half main body 1. A wire extension roller for an underground wire, which is provided with a female screw hole 12 into which the male screw 8 carved in the screw rod 9 is screwed, at the opening/closing end of the lower half main body 2.
