PURPOSE:To prevent backlash and positional displacement from being produced and thereby effect accurate adjustment by quickly and easily fixing a holder on a body by vertically moving a coupling shaft with forward and backward movement of one tapered clamping tool. CONSTITUTION:The flange-shaped head part 13 of a coupling shaft 14 having a radially tapered hole 25 in its shaft part 19 is engaged with an engagement concave portion 16 provided on the mounting side of the holder 3 of a head body 4. The shaft part 13 is slidably inserted in an axial hole 20 provided on the mounting side of the holder 3 of the head body 4. In addition, the holder 3 is connected to the body 4 freely to make contact/separate with/from the body 4 by a tapered clamping tool 26 inserted into the hole 25 in the shaft 19. Accordingly, the holder 3 can be rapidly, easily and accurately fixed. |
