Description of the Related Art Conventional haircutting scissors are widely used in which the flat parts formed on the base of the blade are in contact with each other and are pivotally attached by a pivot. However, if the flat parts of both blades are in contact with each other, the opening and closing operation will be heavy and fatigue will increase, which is not suitable for long hairdressing work, but also due to the habit of the user and the opening and closing operation force. There is a problem in that twisting occurs between the hairs and the hair cannot be cut smoothly and under uniform conditions.

おいても疲労を軽減させることができる。As described above, according to the structure of the pivotal attachment portion of the haircutting scissors of the present invention, the flat portion formed on the base portion of the blade body is pivoted by the pivot shaft at a small interval. In the hairdressing scissors to be worn, the lower end of the pivot is screwed to the flat portion of the lower blade, and the upper portion of the pivot is vertically slidably inserted into the flat portion of the upper blade. Since the central portion of the short tubular body is inserted through a bearing to bring its upper-end large-diameter head into contact with the upper end surface of the short tubular body, since the flat portions of the two blade bodies are not in sliding contact with each other, Not only the occurrence of creaking can be eliminated, but also the opening / closing operation of the blade body can be performed lightly through the bearings, and therefore fatigue can be reduced even during long hairdressing work.
