Claim 0:
1. A scanner having a flexible probe, comprising:
a probe fixing body which moves while coming into contact with a surface of a bent fitting pipe and to which a probe body is fixed;
a flexible connecting chain part installed to be connected to one end of the probe fixing body and having a freely bendable structure;
a sensor installation part installed on an end of the flexible connecting chain part and configured to move while pressed against the surface of the fitting pipe;
a sensor flexibly connected to the probe fixing body, an end of the sensor is installed on the sensor installation part to scan a weld zone of the fitting pipe; and
an encoder part installed to be connected at one side of the probe fixing body and configured to move while pressed against the fitting pipe and detect a moving distance and a position,
wherein the probe fixing body includes ball plungers provided at four positions of a lower surface of the probe fixing body and configured to slidably move the probe fixing body along the surface of the fitting pipe,
wherein the flexible connecting chain part includes:
a chain that is adjustable in length due to having a structure formed with a plurality of joints; and
a sensor seating plate which is installed to be connected to an end of the chain and on which the end of the sensor is seated,
wherein the sensor installation part includes:
a press-applying part coupled to the sensor seating plate and configured to apply a uniform pressure to the end of the sensor;
an elastic coupling part that elastically couples the press-applying part to the sensor seating plate; and
a wheel installed to be coupled to a side portion of the press-applying part and configured to move the press-applying part by rotating in a state in which the wheel is pressed against the surface of the fitting pipe by a magnetic force,
wherein a rotation axis of the wheel is arranged perpendicular to a radius of curvature of the chain.
