<p>A tool assembly is provided to minimize the contact area and the distance between a coupling member and a male spigot by coupling the coupling member with the male spigot using clamping screws. A tool assembly comprises a tool(100), and a coupling member(200). The tool includes a head(110) approaching a workpiece, a male spigot(120) extended from the rear end of the head, and a flange(150) formed at the boundary between the head and the male spigot. The coupling member has a first part(210) formed with cavities in which the male spigot is received, and a second part(220) connected to a driving part. The male spigot has a tapered surface. Through holes(212-1,212-2) are connected to the cavities. The front ends of screws(411,412,413) coupled through the through holes press the tapered surface of the male spigot.</p> |
