Patent ID: 8402989

Claim:
A telescopic pump nozzle adapted for engaging with different tire valves for tire inflation, the pump nozzle comprising: a shaft, which has a first end and a second end, including a channel formed therein and communicating the first end with the second end, a slider formed on an outer periphery of the shaft and disposed between the first and second ends, a pusher defined at the top of the first end and disposed opposite to the second end and adapted to push needles of the tire valves for tire inflation, and a threadedly coupled portion defined at the first end, with the second end coupled to an air pipe of the pump; and a tube, which has a first end and a second end, including first and second connected sections formed on an inner wall of the first end, an annular section defined between the first and second connected sections, with the first connected section, the annular section and the second connected section contiguously formed on the inner side of the first end, a compartment defined in the second end, and at least one O-ring mounted on the shaft and abutted against the inner wall of the compartment in an air-tight manner, with the slider slideably disposed in the compartment, with the second connected section provided between the first connected section and the compartment, with the shaft slideably disposed in the compartment of the tube, with the threadedly coupled portion selectively coupled to the second connected section in a screwing manner; wherein a seal is provided at the annular section and is abutted against the tire valves in an air-tight manner when the tube is engaged with the threads of the tire valves; and wherein a blocked flange is formed in the tube between the compartment and the second connected section and blocking the slider; wherein a diameter of the second connected section is smaller than a diameter of the first connected section and a diameter of the compartment wherein the tube is able to be switched between a first position and a second position for selectively engaging with American and French valves for tire inflation; and wherein when the tube is in the first position, the threadedly coupled portion is engaged with a threadedly connected portion and the first connected section is engaged with threads of the American valve for tire inflation; and wherein when the tube is in the second position, the threadedly coupled portion is disengaged from the threadedly connected portion which is engaged with threads of French valve for tire inflation.
