ABSTRACT:
A sprayer includes a base, a container, a drive device, a pumping device, and an outlet pipe. The drive device includes a drive shaft and a drive handle. The pumping device includes a pressure tank, a pressure release valve, a piston cylinder, a barrel, a piston, a piston rod, two guard brackets and a crank. The container is provided with a plurality of fixing plates secured in the fixing brackets of the base so that the container is combined with the base solidly and stably to enhance the strength of the sprayer. The piston rod is encompassed and protected by the barrel, and the crank is encompassed between and protected by the two guard brackets, so that the piston rod and the crank are operated exactly and stably.
