  • Publication number: 20130306761
    Abstract: A washing apparatus with an adjustable water spraying head includes a water inlet tube, a water guiding tube and a water spraying head. A second connecting base of the water guiding tube engages with a first connecting base of the water inlet tube. A plurality of first positioning holes that are against a first positioning unit of the water inlet tube are circularly formed at the engaging side. The water spraying head is plugged into a water outlet end of the water guiding tube, and a second positioning unit is located at outer periphery of a connecting tube. The second positioning unit is against a second spring and wedged in a second positioning hole of the water guiding tube. According to the structure stated above, the adjustment of the water spraying head is more convenient without frequently moving the water inlet tube, which causes water randomly spraying.
