Claims

[Claims for Utility Model Registration] A cylinder and a piston constituting an actuator, a basic pipe fixed to the cylinder, a shaft fixed to the piston and extending inside the basic pipe, and a cylinder spaced apart from the shaft. a fixed sleeve and a distance collar; a taper cone slidably fitted on the shaft and having a tapered outer periphery; and a tapered cone movably disposed radially through the basic pipe and having a tapered inner surface. The basic pipe is inserted into the pipe to be gripped, and the shaft is moved by an actuator, so that the spring and the spring are elastically loaded between the sleeve and the distance collar and the taper cone. A mandrel characterized in that a tipter is pushed by a taper cone and extends in the radial direction to fix a pipe to be gripped at multiple positions.
