Claims

[Scope of claim for utility model registration] 1. The scissors bodies are rotatably locked to each other at the fulcrum part,
The fulcrum locking body includes a screw that is loosely fitted into both scissors bodies from one side of the fulcrum part of both scissors bodies, and a small screw that is screwed onto the screw on the other side of the fulcrum part of both scissors bodies. The back of the head of the screw is rotatably supported on the bottom of a shallow cavity recessed in the outer surface of the fulcrum part of the one scissor body, and the small spring nut is supported by a leaf spring. 1. A pair of scissors characterized in that the body is wound in a spiral shape, and a female thread into which the screw is screwed is cut at the central winding opening. 2. The scissors according to claim 1 of the utility model registration claim, wherein the mainspring nut has a conical coil shape. 3. The scissors according to claim 1 or 2, wherein the back surface of the head of the screw is supported on the bottom surface of the concave cavity via a small diameter ball.
