<p>PURPOSE:To perform wire inserting work smoothly by providing an inclining face on at least one of the outer circumference of a clamping metal or the inner circumference of a receive metal then clamping the end of wire between the outer circumference of the clamping metal and the inner circumference of the receive metal, thereby securing a bundle of wire to a pulling wire. CONSTITUTION:A tubular receive metal 2 having outer diameter shorter than the inner diameter of a tube 1 has one open end a dn the other end having a hole, where an inclining face 4 is provided at the inner circumference. A spherical clamping metal 7 secured with a pulling wire 6 for pulling a wire inserted into the hole 3 is placed in the receive metal, then a plurality of wires 8a, 8b, 8c are manually pushed into an annual space formed between the inclining face 4 at the inner circumference of the receive metal 2 and the outer circumference of the clamping metal 7. When the pulling wire 6 is pulled, the wires 8a, 8b, 8c are secured between the receive metal 2 and the clamping metal 7 through wedge function of the inclining face 4. The pulling wire 6 is passed through the tube 1, under this state, then it is pulled to pass the wire.</p> |
