Abstract: A sprayer attachment for a hand-supported power tool comprises a motion converting mechanism, a pumping mechanism, a spray assembly and a housing. The motion converting mechanism has an input shaft. The pumping mechanism is driven by the motion converting mechanism. The spray assembly is fluidly coupled to the pumping mechanism. The housing assembly couples the motion converting mechanism, the pumping mechanism and the spray assembly. The sprayer attachment may further comprise an anti-rotation bracket extending from the housing. The sprayer attachment may further be coupled to a handheld power tool, such as a cordless drill or a reciprocating saw, with the anti-rotation bracket.
