the second comparison result is: the preset impact frequency parameter is smaller than the rated impact frequency of the impact equipment, and the preset impact equipment rotating speed parameter is smaller than the rated rotating speed of the impact equipment;
the third comparison result is: the preset impact frequency parameter is greater than the rated impact frequency of the impact equipment, and the preset impact equipment rotating speed parameter is greater than the rated rotating speed of the impact equipment.
4. The method for controlling an impact tool disc device according to claim 3, wherein the step of controlling an impact device (02) to adjust the impact frequency of the impact device and the rotational speed of the impact device to match the rotational speed of the tool disc, or controlling a tool disc (01) to adjust the rotational speed of the tool disc to match the impact frequency of the impact device and the rotational speed of the impact device, according to the comparison result comprises:
when the comparison result is the second comparison result, transmitting the second comparison result to a control module (3), wherein the control module (3) controls an impact device (02) to adjust the impact frequency of the impact device and the rotating speed of the impact device to be respectively matched with the rotating speed of the cutter;
when the comparison result is the third comparison result, the second comparison result is transmitted to the control module (3), and the control module (3) controls the cutter head (01) to adjust the rotation speed of the cutter head to be matched with the rated rotation speed of the impact equipment and the rated rotation speed of the impact equipment.
