Claim:
A corkscrew for removing a cork which covers a bottle mouth of a wine bottle, comprising: a support body placed over said bottle mouth; a removal handle, rotatably engaged with said support body, having a coupling hole with a female spiral formed therein; a conveying screw, coupled to said coupling hole of said removal handle, for forwardly moving with rotation along said female spiral by a rotational force applied to said conveying screw and for moving backwardly, without rotation of said conveying screw, by a rotation of said removal handle; a holding screw, aligned with and coupled to, as a single body, in a front end of said conveying screw, for penetrating into said cork by the forward rotating movement of said conveying screw and for removing said cork from said wine bottle by the backward movement, without rotation, of said conveying screw; and a push-rotation handle, mounted on an upper portion of said conveying screw, for applying said rotational force to said conveying screw, wherein said coupling hole of said removal handle comprises a cylindrical body having said female spiral formed on an interior of said cylindrical body, to which said conveying screw is spirally coupled; and wherein said removal handle comprises a grip portion extended from an upper exterior portion of said body in the radial direction; and a coupling support portion, extended from a lower exterior portion of said body in a radial direction and retained by a catching portion extended from an upper portion of said support body in the counter radial direction, for rotatable coupling to said support body without a movement in an axial direction.
