The drilling operation steps are as follows: one hand holds the handle 1 and the other hand holds the side grip 6 to hold the impact drill, and then the push button 2 is pressed to start the motor driving the impact part 32. The motor drives the transmission gear shaft to rotate, and the transmission gear shaft drives the gear meshing therewith to rotate. The rotation of the gear drives the shaft 33 and then drives the drill head 4 to rotate. After the impact drill is started, it is pushed forward so that the drill rod 42 of the drill head 4 contacts the processing surface, and the processing surface is drilled. The forward push causes the drill head 4 to move backward relative to the drilling machine body 3, and the rotating gear is relatively displaced backward through the shaft 33, and the displacement of the gear drives the rotating second impact tooth member to move forward. The first impact toothed member at the fixed position is displaced. After contact, the first impact toothed member will continue to squeeze the rotating second impact toothed member, so that the second impact toothed member drives the gear, the rotating shaft 33 and the drill head 4 to move back and forth.

In the process of impact drilling, the drill head 4 will drive the buffer The guide frame 53 moves back and forth, wherein the displacement of a group of guide rods 532 of the buffer guide frame 53 in the guide groove 516 cooperates with the bearing 52, which can smoothly guide the lateral displacement of the rotating shaft 33, so that the displacement of the drill head 4 always remains stable to reduce vibration, and the liquid ring 533 that moves with the guide rod 532 in the liquid chamber 515 will squeeze the buffer hydraulic oil in the liquid chamber 515, so that the buffer hydraulic oil flows through the liquid port along with the squeezing of the liquid ring 533, thereby applying damping to the drill head 4 that moves back and forth, so that the drill head 4 remains stable during displacement, and the stability of the drill head 4 during displacement is further improved to reduce shock, and at the same time, the guide rod 532 will drive the ring shell through the linkage block 535 during the displacement process. 542 is reciprocated, and the displacement of the ring shell 542 will repeatedly squeeze the folded airbag 544 on one side to expand the folded airbag 544 on the other side. The internal gas of the squeezed folded airbag 544 will be discharged into the ring shell 542 through its corresponding outlet valve pipe 546, and the expanded folded airbag 544 will be inflated through its corresponding inlet valve pipe 545. The reciprocating inflation and deflation operation of the folded airbags 544 on both sides can buffer the high-frequency displacement of the drill head 4 to reduce shock, so that the drill bit stabilizing device can stabilize, buffer and reduce shock of the working drill bit through various operations, reduce the fatigue of the user caused by vibration, and improve the comfort during operation. The buffering and shock reduction operation is performed through the above steps;The dust-proof operation steps are as follows: the reciprocating inflation and deflation operations of the folded air bags 544 on both sides can continuously supply air to the annular shell 542, and the gas in the annular shell 542 passes through the linkage block 535 and the guide rod 532 through the air inlet 536 to enter the air groove 518, and then the gas in the air groove 518 is discharged through the air outlet 519, and the airflow discharged from the air outlet 519 is sprayed to the guide vanes 554 and the cone sleeve 553 of the guide member 55, and the airflow is sprayed toward the drill head 4 along the guide of the cone sleeve 553, the guide vanes 554 and the guide sleeve 56, and the guide vanes 554 are affected by the airflow to drive the cone sleeve 553, the back ring 552 and the track ring 551 to rotate, so that the ejected airflow forms an airflow barrier between the hole position of the guide sleeve 56 and the gap between the rotating shaft 33, so that the dust and debris generated during the drilling process cannot enter the interior of the equipment and affect the stability of the equipment during processing. The dust-proof operation is performed through the above steps. ;
