Title:
SUCKER
Document Type and Number:
WIPO Patent Application WO/2015/018319
Kind Code:
A1
Abstract:
Disclosed is a sucker, wherein a front side of a sucker body (01) is made as an outwardly convex surface, a rear side of the sucker body is connected to a pull rod (02), and the pull rod passes through an adapter (03) to connect with a flippable handle (04). When the handle is retracted to the adapter, thus forming a negative pressure cavity (11), the air within the negative pressure cavity is discharged as much as possible, ensuring a high degree of vacuum within the negative pressure cavity and ensuring the suction strength; and when the handle is flipped away from the adapter, the front side of the sucker body restores to the outwardly convex surface, quickly eliminating the negative pressure cavity so as to facilitate removal of the sucker from a contact surface.
