PROBLEM TO BE SOLVED: To provide a unit type bolt comprising a germanium plating material, a unit type main shaft part and an inclined fixation screw of a 35° of thread of an auxiliary shaft part, and provide an L-shaped tool having a 17° of inclination.SOLUTION: An L-shaped tool (a side view, a plane view) comprises (1) a unit type bolt main shaft part, (2) a fixation screw, (3) a bolt and a 35° of inclined thread, (4) an auxiliary shaft bolt and a 35° of thread, and (5) an auxiliary shaft part; and has a 17° of inclination with physical priority. Also, the characteristic of a bolt close to that of an insulator can be made by using a germanium material, so that electricity flows slowly. Further, in medically, the L-shaped tool has an excellently good state, and eliminates fatigue feeling even in long manual work.SELECTED DRAWING: Figure 1 |
