PURPOSE: A driver tool for coupling and separating a stud of a nuclear reactor is provided to accurately couple and separate a stud by delivering a power into a coupling direction and a separating direction of the stud. CONSTITUTION: A driving part(110) includes a driver, a lifting unit, a driving unit, and a frame. The lifting unit moves the driver up and down. The driving unit rotates the driver into a forward and reverse direction. The frame is connected to a bottom plate. The frame supports the driver and the driving unit. A guide part includes a supporting tube, a holder tube, a guide cylinder, and a supporting leg. The supporting tube is mounted in a circumference of a stud(10). The supporting tube is slidably received to the holder tube. The guide cylinder moves the supporting tube up and down. The supporting leg supports the supporting tube. A position correcting unit corrects a position of the driving part. A coupling unit(130) couples and separates the driving part and the guide part. |
