A sprayer gun includes a handle and a valve stem slidably received in the rear portion. A stop is secured to the valve stem and engaged with the handle, and has one or more ratchet teeth. A spring lever has one end secured to the handle and has a number of ratchet teeth for engaging with the ratchet teeth of the stop and for preventing the stop from being moved forward relative to the spring lever. The water is thus allowed to continuously flow out of the sprayer gun without continuously depressing the control hand grip toward the handle by the the ratchet teeth.
