Abstract: A joint structure for an air nozzle contains a valve joint connected on an air nozzle to fill air, with the air nozzle including outer threads defined around an outer peripheral side thereof. The valve joint includes a body having a hole defined therein, an inlet communicating with the hole, and at least one orifice penetrating from an exterior environment to the hole. At least one limiting member is secured and moves in the at least one orifice and has meshing teeth formed on one end thereof to correspond to the hole. The meshing teeth engage with the outer threads of the air nozzle. The at least one limiting member has a defining segment arranged on another end thereof. A controlling assembly is fitted on the body and is used to control the at least one limiting member to move in the at least one orifice.
