The invention relates to a tire inflation tool, and discloses a button type labor-saving rapid inflation nozzle which comprises a valve sleeve, a valve element and a button assembly, and the valve element is inserted into the valve sleeve in a sleeved mode; an insertion hole and a jacking ring arranged at the lower end of the insertion hole are formed in the upper end of the valve sleeve; the valve element comprises an outer element body, an inner element body inserted into the outer element body in a sleeved mode and a connecting part. An elastic clamping ring is arranged at the upper end of the outer core body, and the elastic clamping ring is close to the top pressing ring and located below the top pressing ring. The connecting part comprises a valve core seat, a connecting pipe and a connector; the button assembly comprises a button part and a pair of supporting pin shafts; the button part comprises a pressing plate and a pair of jacking parts arranged at the end of the pressing plate, and the jacking parts are rotationally connected with the valve sleeve through supporting pin shafts. And the valve core seat is pressed against the top pressing part. The elastic clamping ring can be conveniently driven to expand outwards and deform in a labor-saving mode through the button assembly, the elastic clamping ring is prevented from being in contact with tire valve threads during installation, and the threads can be effectively protected. The elastic clamping ring clamps the tire valve through multi-point uniform distribution, and the connection stability of the inflation nozzle and the tire valve can be improved.
