PURPOSE:To make an insertion amount accurate by forming locating connection surfaces on a connection of an inserting portion of a blade edge tool body and an insertion hole of a base tool body and providing an engaging member removably attached to the blade edge tool body on the base tool body to be engaged therewith on the connection surface position. CONSTITUTION:A locating connection surface 37 is formed along the direction orthogonal to the direction of inserting a blade edge tool body 22 in a connection of an inserting portion 34 of said body 22 and an insertion hole 28 of a base tool body 21. Also, said body 21 is provided with an engaging ball 47 removably engaged with a carrier section 32 of an inserting section 34 of said body 22. When said body 22 is inserted to abut against said surface 37, the ball 47 is press fitted in the carrier section 32 by an operation of a clamper 44 to maintain fixedly an insertion amount. When released, the ball 47 is released from press fitting by the operation of clamp 44 so that said body 22 can be removed. |
