ABSTRACT:
An unfastening device for unfastening pipe fasteners includes a base and a first clamp plate extends from a top of an end of the base. A movable member is slidably mounted to the base and movable between the two ends of the base. A second clamp plate and a third clamp plate extend from a top of the movable member. A cable unit includes a head which extends through one of two ends of the base and is stopped by an end of the movable member. A flexible cable extends through the head and has a first end fixed to the first board of the base. By pulling the second end of the flexible cable, the movable member is moved along the base and the distance between the first clamp plate and the second and third clamp plates can be adjusted.
