A liquid dispenser includes a hollow shank, a dispensing head longitudinally mounted to a first end of the hollow shank, a control device longitudinally mounted to a second end of the hollow shank and a sheath detachably mounted to the first end of the hollow shank for protecting the dispensing head after use. A passage is defined in one end of the hollow shank for communicating with an inner periphery of the hollow shank and the dispensing head such that the liquid contained in the hollow shank can flow into the dispensing head. The control device is provided to selectively close/open the passage for controlling the output quantity of the liquid dispenser. |
