Claim 0:
1. A high-frequency composite impactor comprising a high-frequency axial impact assembly, a torsional impact assembly, and a lower joint, wherein:
the high-frequency axial impact assembly includes: an upper self-excited oscillation cavity, a lower self-excited oscillation cavity, an adjustment block, and a lock nut;
the upper self-excited oscillation cavity has an upper end configured with an arc flow channel port, and a lower end configured with a conical end face to form a fluid inlet, and four circumferential positioning holes;
the lower self-excited oscillation cavity has an inner wall and a lower end configured with a conical flow channel port forming a groove structure with the inner wall;
the adjustment block is between the lower self-excited oscillation cavity and the lock nut;
the lock nut has an inner wall with a hexagonal channel and an external thread;
the torsional impact assembly includes: an upper end cover, a lower shell, a pendulum, a reversing switch, a lower end cover, a nozzle, a connecting block, and a retaining ring;
the lower shell is between the upper end cover and the lower end cover, connected by screws;
the nozzle is inside the lower end cover to form a torsional impact part;
the connecting block is between the lower joint and the lower end cover; and
the retaining ring is between the lower joint and the connecting block.
