ASSEMBLY MEMBER FOR FLAT TOOL TO REDUCE ASSEMBLING TIME OF FLAT TOOL, TO MINIMIZE NUMBER OF NECESSARY ELEMENTS AND TO REDUCE PRODUCTION COSTS

摘要

PURPOSE: An assembly member is provided to reduce the assembling time of a flat tool, to minimize a number of necessary elements for the assembly and to reduce the entire cost. CONSTITUTION: An assembly member(1) contains a cylindrical unit(4) centering a rotating shaft(12). More than two devices are offered in the cylindrical unit to combine and tighten a flat tool with an opening by rotating a rotating member(1) under 360 degrees centering the rotating shaft without a bonding member or other mechanical fixing elements. Thereby, the assembling time of the flat tool is reduced, a number of elements for the assembly member is minimized and the entire cost for the operation is decreased.
