A corkscrew incorporating a support arm with two articulated sections capable of acting independently and sequentially by resting on a bottle's mouth. The sections are connected to each other through a joint that has a spring that causes one of the sections to seek out the side or mouth of the bottle where it is to be positioned, without the need for a corkscrew user to deliberately perform this operation. The spring is set at the level of the articulated joint between the arm and body or handle, the ends of which form aligned and opposing pivots that emerge laterally from the body, where the arm incorporates a circumferential arrangement of notches over which the pivots must move during the swinging movement of the arm with respect to the body. This prevents undesired movement between the arm and the body, no matter what relative position is chosen for them.
