The corks for sealing wine bottles can be opened, but the following shortcomings still exist when using it in our daily life: 1. the stroke of gear driving mechanism is the length of rack, the length limits the length for the screw to insert and pull out the corks and the operation handle of the gear driving mechanism can only drive the screw to make one-direction movement during its movement, so the aforesaid corkscrew requires rotating the actuation lever back and forth twice during application to pull out corks from wine bottles and remove the corks on the screw, not only leading to inconvenient operation, but also wasting more time and strength when rotating the lever twice back and forth, thus adding more burden on the person for opening bottles; 2. since the abovementioned corkscrew is mostly applied in some high-class consumption pleasure places particular about elegance of bottle opening movements, while the corkscrew requires rotating the lever twice back and forth, such movement lacks of elegance, thus degrading the high-class consumption pleasure places and decreasing the service quality to some extent.

BRIEF SUMMARY OF THE INVENTION

The present invention addresses the technical problem, through overcoming the abovementioned defects of the existing technology, by means of providing a timesaving corkscrew with the least resistance and convenience for operation.
The technical solution of the present invention is to provide a corkscrew which comprises a tubular body with opening on both ends, driving mechanism set inside the tubular body, screw assembly, screw guiding assembly for screw of the screw assembly to pass through, elastic limit piece, and actuation lever on the top of the tubular body and capping assembly at the bottom of the tubular body respectively, wherein the driving link of the driving mechanism is connected with the actuation lever, the driven link is connected with the screw assembly; the screw guiding assembly is slide-fitted in the tubular body; the capping assembly is set on the inner wall of the tubular body, which forms a shape matching the shape of the neck of bottle; the elastic limit piece is installed between the tubular body and the capping assembly, the elastic limit piece can prop up the neck of bottle so as to limit the axial sliding of screw guiding assembly, the driving mechanism is a linkage driving mechanism.
After adopting the abovementioned structure, comparing with the existing technology, the present invention has the following favorable effects:

1. The linkage driving mechanism of the corkscrew for the present invention can change the relative length of the various members without adding the stroke of the driving link so as to prolong the stroke of the driven link a lot, so the corkscrew for the present invention can pull out corks from wine bottles and remove the corks on the screw by rotating the actuation lever once back and forth during application, not only leading to convenient operation, but also saving time and strength, thus relieving the burden on the person for opening bottles;
2. Since the corkscrew for the present invention is mostly applied in some high-end consumption places particular about elegance of bottle opening movements, while the corkscrew only requires rotating the lever once back and forth to pull out corks from wine bottles and remove the corks on the screw, the elegant movement upgrades the high-end consumption pleasure places and improves the service quality to some extent.

As further improvement, a rolling cutter is set on the capping assembly for the present invention, tinfoil for externally sealing the bottle can be easily removed through rotating the bottle, so as to improve the practicability of the present invention.
