The utility model relates to a conventional gimlet operated by a single hand. An inclined face which is inclined along a shaft direction by certain angle is machined and formed a slideway named by winding a cylinder rod member. The slideway can relatively slip with a fixed slide block nail to cause to form the rotating of a round rod member and generate certain torques. A drill bit mounted at the lower end of a sliding inclined rod is used for cutting work members. A spring in a sliding jacket tube is compressed to generate an elastic force. The sliding jacket tube is only pressed to cause to facilitate the gimlet to work when the utility model is operated.
