ABSTRACT:
A distance and orientation adjustable suction device includes two suction cups and a controlling mechanism connected between the suction cups. Each suction cup has a rotatable mounting block. The controlling mechanism includes a main body forming a knuckle joint with the mounting block of one suction cup and defines a channel movably receiving a rack that threadingly engages a internally-threaded cylinder that forms a knuckle with the mounting block of the other suction cup. Thus, the suction cups are each rotatable about two axes with respect to the main body and are linear movable with respect to each other. Further, the threading engagement between the cylinder and the rack allows for minute adjustment between linear distance between the suction cups.
