ABSTRACT:
A manual wine bottle opener includes a main body, a fixing base, a piston rod, a press lever, a valve base, a thimble, a sleeve and a slide member combined together. The press lever has one end pivotally combined with a connecting member, and the piston rod has its lower end fitted with a piston. The valve base has its interior provided with a non-return valve and its lower side fixed with an insert needle. By reciprocally pulling and pressing the press lever for moving the piston up and down repeatedly, air can be pumped into the wine bottle through the insert needle for removing the cork of the wine bottle from the bottle mouth, able to uncork the wine bottle conveniently and quickly. Then the sleeve is turned around to actuate the slide member to whirl and move downward to push and disengage the cork from the insert needle.
