Abstract: A cork opener includes a hollow handle, an air pump, first and second hollow fitting units; the pump has a piston rod connected to the handle; the pump is passed through upper end of the first fitting unit, and displaceable relative to the same; the first unit has a hole at lower end for an outlet needle of the air pump to be passed through; the first fitting unit has a displacement portion, which is extended from the lower end, and formed with guide gaps, and which is passed through upper end of the second fitting unit, which has position-limiting blocks respectively movably held in the guide gaps; thus, a cork of a bottle can be removed from the bottle by means of moving the handle up and down to pump air into the bottle after the needle has been inserted through the cork to communicate with inside of the bottle.
