Claims

[Claims for Utility Model Registration] 1. A pipe wire threading tool in which a guide 1 is attached to the tip of a coiled spring-like wire 3 for feeding into and pulling out from a pipe in a rotating state, which includes: Wire tip 3
A base material 2 which can be bent and deformed together with the wire tip 3b is provided inside the wire, a strain gauge 9 is attached to the base material 2, and an electric wire 10 for transmitting information from the strain gauge 9 is connected to the coil spring shaped wire. 3. A pipe fitting led out from the proximal end. 2 A pipe wire threading tool in which a guide 1 is attached to the tip of a coiled spring-like wire 3 for feeding into and pulling out from a pipe in a rotating state, wherein the wire tip 3 of the coiled spring-like wire 3
b is formed in the shape of a tightly wound coil spring, sensors 8a and 8b are provided at the wire tip 3b to detect the amount of extension thereof, and the sensor 8a is placed at the approximate center of the coil diameter of the wire tip 3b at the tip of the wire. A sensor holding means 14 is provided to hold the sensor 3b even in the bent state, and the electric wire 10 for transmitting information from the sensors 8a and 8b is provided.
A pipe wire passing tool led out from the base end side of the coil spring wire 3.
