摘要
The present invention is to provide an automatic-switch nozzle head having two valve mouths and a single-mouth nozzle head (50). The nozzle head comprises a main body (10), a connecting mouth (20), and a valve plug (40). The connecting mouth (20) has a mouth hole (21) to receive one end of the valve plug (40) to be disposed in the valve hole (11). At least one end or two ends of the valve plug (40) are formed with spaced clamping claws (44) arranged in a circle. The outer wall of each clamping claw (44) is formed with a curved portion. The interior of the valve plug (40) is formed with at least one flow passage to communicate with the mouth hole (21). The main body (10) has an air supply hole (12) to connect with an air pressure source. The valve plug (40) can be moved between a first position and a second position of the main body (10).
