PROBLEM TO BE SOLVED: To remove a cork just by revolving a handle with a helical drill on its lower section. SOLUTION: An insert die 3 is screwed into a main body 2 by screws 6 provided on both of them, and clutch sections 5 are formed on the upper section of the insert die 3 and the lower section of a handle 1, and when the handle 1 is revolved, first a helical drill 4 is bitten into a cork, and then when the upper clutch section 5 reaches the lower clutch section, the biting of the cork is completed, and the handle 1 and the insert die 3 are revolved simultaneously. The revolution of the insert die 3 is moved to the oblique upper while being revolved by the guide of a screw 6 of the main body 2, and the cork into which the helical drill 4 is bitten is moved in a same manner, and the cork is removed slowly by the small force, and the helical drill 4 is set in the state of being pulled while revolving the work toward oblique upper, and the damage to the cork is small, and the end of the helical drill 4 is not protruded from the bottom of the cork.
