An opener to lift a tab of an easy-open can comprises a long-narrow lifting shaft whose front end disposes a keen prying section. A ring handle at a top rear section of the prying section is extensively disposed upward, and a thin protecting plate is extensively disposed outward for providing a protecting function. The keen prying section is inserted into a top edge of an opening of the tab. Thereby, a front portion of the lifting shaft stretches beyond one side of the easy-open can for forming a fulcrum. An upward pulling from users allows a front end of the tab to break the top lid of the easy-open can for forming an infirm breach on one section of the top lid. Further by means of a rear portion of the lifting shaft striding across a correspondent side of the easy-open can for forming the other fulcrum, an opposite and upward pulling force on the ring handle allows the rising prying section to lift the tab. Thus, the entire top lid of the easy-open can could be smoothly pulled apart and discarded. Thereby, by means of the leverage, a simplified process via a pressing and a pulling permits a speedy operation to open the can with an effort-saving effect.
