Abstract
A sucker includes: a main body having a bottom face formed with an annular abutment; a disc body made of a flexible material having a tapered annular wall, the disc body being disposed under the bottom face of the main body, an outer circumference of the annular wall being formed with a lip edge positioned below the annular contact area; an air chamber being formed in the disc body; an air-sucking passage and a fast flow way; the air-sucking passage having a first end in communication with the air chamber of the disc body and a second end passing through the disc body and the main body to communicate with the fast flow way. When the sucker sucks a surface of an object, the air in the air-sucking passage is sucked into the fast flow way.
