The invention discloses an anti-deviation fast drilling tool, comprising an anti-deviation sub, an adjusting sub, an impacting mechanism and a drill bit connected sequentially from top to bottom, wherein the anti-deviation sub has a first axis, the adjusting sub has a second axis, the first axis and the second axis are not collinear, a drilling fluid passage is formed in the impacting mechanism, the impacting mechanism comprises an impacting cavity that is hollow, the upper portion of the impacting cavity is provided with a nozzle, a control valve is arranged inside the impacting cavity belowthe nozzle, and reciprocated hammering can be periodically performed in case of a change in the inner pressure of the impacting mechanism. The anti-deviation fast drilling tool can provide deviation prevention for formations difficult to drill, bearing gravel and the like, rock breaking efficiency of the drill bit is improved, the service life of the drill bit is extended, and drilling speed is increased.
