In this scissors, a compression coil spring is mounted between both handle parts, and both blade parts open each other by the elastic force of the compression coil spring during use. When the handle portions are closed to each other against the elastic force of the compression coil spring, the blade portions close each other, and when the force for closing the handle portions is released, the blade portions open due to the elastic force of the compression coil spring. When not in use, both handle parts are closed together with both blade parts, and a retaining ring attached to one handle part is hooked on the other handle part to prevent both handle parts and both blade parts from opening.

防止する。The cantilever-shaped elastic body 1 is provided at the end portions of the gripping portions 8 and 9 facing each other, which are close to the opening / closing center portion 3.
Numerals 0 and 11 are integrally extended toward the base end portions so as to form a V shape with respect to both grip portions 8 and 9. Both elastic bodies 1
Protrusions 14 and 15 are formed at the free ends of 0 and 11 via stepped portions 12 and 13. As shown in FIG. 1 and FIG. 2, when not in use, both elastic bodies 10 and 11 cross each other in an X-shape and overlap with each other, and the protrusions 14 and 15 at the free ends of both elastic bodies 10 and 11 form the step. Locking part 14 near the parts 12 and 13
a and 15a are locked to each other. Therefore, the opening of the grip portions 8 and 9 of the handle portions 4 and 5 is caused by the locking portions 14a and 1
It is prevented by 5a that the two blade parts 6, 7 are prevented from being opened accidentally.

The protrusions 14 and 15 of 0 and 11 are attached to the contact portions 14b and 15b.
Match with each other. Therefore, an elastic force acts between the contact portions 14b and 15b, the grip portions 8 and 9 of the handle portions 4 and 5 are opened to each other, and the blade portions 6 and 7 are also opened. Then, as shown in FIG. 5, when both grips 8 and 9 are closed against each other against the elastic force of both elastic bodies 10 and 11, both elastic bodies 10 and 11 are bent and both blade portions 6 and 7 are closed. When the force applied to both grips 8 and 9 is relaxed, the elasticity of both elastic bodies 10 and 11 causes both grips 8 and 9 to be released.
Open to each other and both blades 6 and 7 also open.
