PURPOSE:To perform a work easily and efficiently by constituting a multiple connecting rods one end of which is connected to a central connecting member and the other end is coupled with a body frame with two kinds of rods for fine adjustment and coarse adjustment. CONSTITUTION:A pin 26 is inserted into a raial direction pin hole 9 of a central connecting member 2 to fit the first coupling member 10, and one end of a fine adjusting rod 4 is connected with a connecting member 14. A screw rod 20 with a connecting rod 24 is screwed to the other end of the rod 4 so as to perform the fine adjustment by means of the screw rod 20. A body coupling member 8 is connected to the connecting member 24 with a pin 22. Likewise, one end of a coarse adjustment connecting rod 6 is connected to the central connecting member 2 through the secnd coupling member 40, and a sliding rod 46 fixed to a body coupling member 8 through the connecting member 24 is inserted into the other end. A pin 48 is inserted into a proper combination of individual pin holes 50, 51 of the outer cylinder member 44 of the rod 6 and the sliding rod 46 for coarse adjustment. |
