PROBLEM TO BE SOLVED: To provide a component enabling tip part replacement storage due to attachment/detachment of a transmission component of a tool or instrument stably and comfortably.SOLUTION: In a multipurpose connection gear, as an attachment/detachment function of a transmission component separating a socket part, semi-spherical convex and concave connection gear parts (1, 2) make a slender tip part folded to thereby enable joint replacement of the tip part, and in a function for switching a rotational direction due to connection switching and in a safety aspect, a connected gear idles with respect to an unnecessary load to thereby prevent entrainment. |
