Abstract
A lever corkscrew has a body and a central spindle received inside the body. A transport assembly is slidably mounted inside the body, and two anchors securely are mounted on the one side of the transport assembly. Two arms with tooth-like protrusions are pivoted with the body and the protrusions are engaged with the central spindle. The central spindle is securely mounted on the transport assembly on the one side different with the side mounted with the anchors. When turning up the arms or turning down the arms, the central spindle will be driven up or down and also drive the transport assembly with the anchors to pull out the cork.
