CONSTITUTION: A ring 9 is fitted to the rear end part of a shaft 1 and on the outer peripheral edge thereof a projecting part 91 engaged with the groove on the rear end part inner peripheral face of an operation handle 2, an engaging piece 92 engaged with the groove 80 of a sleeve 8 and a cam piece 93 in an L shaped section are provided. The rear end part of a tool is inserted from the tip opening and the shaft 1 is rotated in the direction shown by T1 while gripping the operation handle 2, then a tapered bush 27 and guide block 7 together with the sleeve 8, further a floating screw 6 are rotated relatively to the shaft 1, the floating screw 6 is advanced to move each claw 5 forward, so each claw 5 gathers to the center in the diameter direction and tightens the tool.
