<P>PROBLEM TO BE SOLVED: To provide the structure of the pivot point of scissors used for cutting hair whose nut body 13 is easily turned, does not easily become loose and is tightened for relatively fine adjustment. <P>SOLUTION: A pivot bolt 6 is inserted in the shaft hole 5 of blades 1, 2, an annular plate 10 is inserted in the pivot bolt 6 and a nut body 13 is screwed on to be fixed. The nut body 13 is formed with a storage section 12 and a bearing 15 is energized to the outside in the axis direction through a spring 14 for the bearing 15 to be fitted in the bearing holes 8 of the annular plate 10. With the rotation of the nut body 13, the bearing 15 rotates and moves to adjoining ones of the bearing holes 8 one after another freely intrusively fitted into and coming out from the holes. <P>COPYRIGHT: (C)2012,JPO&INPIT |
