1. A double-use nozzle adapter, comprising:
a main body, defining a first end and a second end opposite to the first end along a first axis, the first end having a vent, the second end having a first threaded hole and a second threaded hole that are made coaxial to each other, the second threaded hole and the vent being communicated through an action chamber located therebetween, and the main body having two through holes;
a switch unit, being rotatably mounted around an outer periphery of the main body, the switch unit including a shifting member and two rigid retaining members, each of the rigid retaining members being located between the shifting member and the main body, the shifting member shifting each of the rigid retaining members between a first position and a second position, the shifting member having two shifting grooves, and each of the two rigid retaining members being received in a respective groove of said two shifting grooves, so that when each of the rigid retaining members is in the first position, each of said respective groove of said two shifting grooves makes each of the rigid retaining members pressing against a needle, and when each of the rigid retaining members is in the second position, each of the rigid retaining members is allowed to move in said respective groove of said two shifting grooves, wherein each of said two shifting grooves is curved to fit the outer periphery of the main body and defines a first groove end and a second groove end, in which the first groove end has a radial depth that is smaller than a radial depth of the second groove end, and each of the rigid retaining members passes through one of the through holes of the main body, respectively; and
a needle unit, being slidably installed in the action chamber of the main body and including the needle, in which when each of the rigid retaining members is in the first position, the shifting member drives each of the rigid retaining members to press against the needle, thereby preventing the needle from moving with respect to the main body and making the needle and the first threaded hole connectable to a Schrader valve, and when each of the rigid retaining members is in the second position, each of the rigid retaining members is movable between the shifting member and the main body along a direction of a second axis that is perpendicular to the first axis, so that the needle is allowed to move with respect to the main body and make the needle and the second threaded hole connectable to a Presta valve, wherein the needle has an outer periphery provided with a positioning groove that is positionally corresponding to each of the through holes, so that when each of the rigid retaining members is in the first position, each of the rigid retaining members is tightly sandwiched between one of the first groove ends and the positioning groove, and when each of the rigid retaining members is in the second position, each of the rigid retaining members is moveable at one of the second groove end to leave the corresponding through hole.
