PURPOSE:To shorten workhours, and also to dispense with any large-sized box body by making recessed parts provided on the lower surface of a box body to be placed on the upper part coincide with projecting parts provided near right and left both ends of the upper surface rear part of the other box body. CONSTITUTION:Recessed parts 8 positioned on the bottom surface part of a box body 11 is made to coincide with projecting parts 5 on a box body 1 upper surface, and the box body 11 is placed on the box body 1 so as to be dropped down. Next, connecting fittings 4 are inserted into connecting groves 3a, 3b on the right and left sides of the box bodies 1, 11, and screws 6 are screwed into tapped holes of the box bodies 1, 11 from round holes on the surface of the connecting fittings 4, so as to fix the box bodies 1, 11. Thereby, it is not necessary to go to the back surface in order to fix the box bodies, and it is not necessary to design large-sized box bodies for the purpose of the operation of the tool. Moreover, work can be reliably and easily performed, and many workhours are not required, and the box bodies are prevented from being made into a large size for handling the tool. |
