Then, the liquid in the second flow channel 19 is guided into the flow distribution disc 1 through the sixteenth communication hole 37 and the sixth communication hole 27, and the liquid in the fourth flow channel 21 is guided into the flow distribution disc 1 through the fourteenth communication hole 35 and the seventh communication hole 28, so that the flow distribution disc 1 is counterclockwise rotated.Secondly, by cooperating with the first connecting hole 22 and the ninth connecting hole 30, and with the fourth connecting hole 25 and the twelfth connecting hole 33, the drilling fluid in the inner cavity of the distribution plate 1 is introduced into the impact hammer 2, pushing the impact hammer 2 and the distribution plate 1 to rotate clockwise, causing the left hammer body 12 to swing in the left arc groove 14, and the right hammer body 13 to swing in the right arc groove 15; finally, the liquid in the first flow channel 18 is introduced into the distribution plate 1 through the thirteenth connecting hole 34 and the fifth connecting hole 26, and the liquid in the third flow channel 20 is introduced into the eighth connecting hole 29 through the fifteenth connecting hole 36, causing the distribution plate 1 to rotate clockwise; repeating the above steps, the present invention converts liquid energy into momentum impact, realizing continuous circumferential impact operation. Furthermore, by setting the left arc-shaped groove 14 and the right arc-shaped groove 15, the stroke of the left hammer 12 and the right hammer 13 is increased; by setting the first, second, third, and fourth inclined holes and installing bypass nozzles 46 in each, a negative pressure zone is formed in the inner cavity of the anvil 3 below the corresponding distribution plate 1, generating a strong negative pressure suction effect. This not only avoids irregular vortices formed between the mandrel, distribution plate 1, impact hammer 2, and anvil 3 due to the reverse backflow of drilling fluid, thus reducing the erosion of the core components such as the distribution plate 1, impact hammer 2, and anvil 3 by the drilling fluid, but also enables the distribution plate 1 to rotate reliably and stably; by setting the central nozzle 45, the drilling fluid entering the main channel can change the magnitude and frequency of the impact force by passing through the working pressure drop of the central nozzle 45.

A filter head 48 is installed on the upper side of the positioning cap 49. The upper part of the filter head 48 has several through-holes. The upper inner side of the filter head 48 has a diversion head 47 whose upper end abuts against the lower side of the inner limiting ring platform 44. The lower part of the diversion head 47 corresponding to the through-hole positions has several through-holes. During use, the diversion head 47 prevents drilling fluid from directly eroding the circumferential impact components; the filter head 48 prevents large solid particles and plugging materials in the drilling fluid from entering the circumferential impact components and causing erosion; and the positioning cap 49 facilitates the positioning and installation of the distribution plate 1, the impact hammer 2, and the anvil 3 together, providing a stable and reliable circumferential impact force.
