Abstract: A valve coupling device includes a body having a transverse hole between two ends of the body. A first nozzle is mounted in an end of the body for coupling with a valve. A first chamber and a second chamber are mounted in the other end of the body and both in communication with the transverse hole. A switch member is pivotally extended through the transverse hole of the body. A second nozzle for coupling with a valve of another type is mounted in the switch member and in communication with the second chamber. When the switch member is in a first position, the first chamber is in communication with the first nozzle and the second chamber is blocked. When the switch member is in a second position, the second chamber is in communication with the second nozzle and the first chamber is blocked.
