2. Traditional percussion drill adopts a wire rope pulling plumb to reciprocate mostly, but a wire rope stability is relatively poor, under the wind-force effect, leads to the plumb to rock easily, leads to the precision relatively poor, even there are two wire ropes of part adoption, but can't guarantee two wire rope synchronous working, still can lead to the plumb to rock.

3. The efficiency of traditional percussion drill impact is very low, and after general winch winding wire rope drove the plumbing and upwards moved a definite position, then loosened the winch, let the plumbing impact down under the action of gravity, then circulate, impact at every turn and all can consume for a long time, influence work efficiency.

To this end, we propose a drill with improved percussion effect.
