Structure improvement of cork bottle opener

Abstract

The invention discloses the structural improvement of a cork bottle opener. It is composed of a hollow cylinder, moving block and central rod. There is a cover locked at the top end of said hollow cylinder. And there is a section of inner thread in the inner wall of top end. The other end is combination end. A snap groove is set at the center of said moving block. The outer edge of said moving block has outer thread, which can be screwed to inner thread of hollow cylinder. The central rod penetrates to the hollow cylinder through a central hole on the cover. A handle is set at one end of said central rod, and a screw drill is set at another end. A constraint flange is set at the middle of central rod. A wedge is set at the end of constraint flange adjacent to screw drill. The wedge can be snapped to snap groove of moving block. The face of said constraint flange adjacent to wedge is jacked to the face of moving block, so that the central rod can be moved up and down associated with moving block, the moving block can be slipped to the fixed position.
