ABSTRACT:
A suction cup removably attached to a housing lifts and moves an object. A venturi removably attached to the housing provides a vacuum effect to secure the suction cup to the object. The venturi includes a pair of opposing ears. When the venturi is inserted into a venturi hole of the housing, the ears compress a pin. When the venturi is rotated to an attached position, the ears do not contact the pin, and a spring biases the pin outwardly to secure the venturi to the housing. The pin is coupled to a button on the housing that can be slid to move the pin inwardly to allow rotation and removal of venturi.
