<p><P>PROBLEM TO BE SOLVED: To provide a sun gear-driven magnification driving tool capable of being freely coupled and removed, and eliminating the need of installing a ring gear and a planetary gear. <P>SOLUTION: The sun gear-driven magnification driving tool includes: a nut driving ring body 111 fastening or loosing a nut 101 by driving an inner ring gear 102 using a sleeve structure 103 in a lower stage; the planetary gear 131 coupled with a sun gear cylinder 121 and the inner ring gear 102; a rocker arm stand 127 of the planetary gear rotating the planetary gear 131 by a shaft column 128 in an upper part, rotating a first projecting shaft-shaped structure 125 of the sun gear cylinder 121 in a first shaft hole 126, and driving while being coupled to a polygon hole 141 having a polyhedral columnar structure 123 on a lower side and recessed into a first inner portion of a stud 140; and the sun gear cylinder 121 wherein a polygon hole 124 having a tooth end 122 and recessed toward a second inner portion on an upper side is driven by an operation tool to rotate, and the first projecting shaft-shaped structure 125 at a lower end is coupled with the first shaft hole 126 to be driven by the operation tool. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
