The invention relates to a drill bit, in particular to an impact continuous meshing multi-orientation cutting efficient hybrid drill bit. The continuous meshing multi-orientation cutting efficient hybrid drill bit comprises a drill bit body. One or more impact cutting mechanisms are arranged below the drill bit body, and each impact cutting mechanism comprises a pair of centrally-symmetrical impacting mechanisms and one or more pairs of centrally-symmetrical cutting mechanisms. Each impacting mechanism is composed of an impacting rotary wheel supporting seat and an impacting rotary wheel matched with the impacting rotary wheel supporting seat in a rotary mode through an impacting rotary wheel shaft. The two impacting rotary wheel supporting seats and the impacting rotary wheels in each pair of impacting mechanism are arranged in a centrally-symmetrical mode correspondingly, every two impacting rotary wheels share one impacting rotary wheel shaft, and impacting teeth are evenly distributed on the surfaces of t
