During operation, the impact electric drill is drilled by impact and drilled by the drill bit. This can reduce and avoid sticking bit with hard objects mixed in hard and soft uneven work. In addition, the impact electric drill has a clutch, which can automatically slip when the tool is overloaded or the drill bit is stuck, thereby preventing the motor from being overloaded and burned. According to the different impact mechanism, the impact electric drill is divided into two types: big tooth type and steel ball type. The impact electric drill is composed of a motor, a variable speed system, an impact structure (toothed disc clutch), a transmission shaft, a gear, a chuck, a drill, a control switch, and a handle. The impact electric drill uses the electric motor as the power source, changes the gears, drives the transmission shaft to rotate, and then meshes with the gears. The gear is a moving gear clutch, and the gear is a stationary gear clutch. On the adjusting ring of the impact electric drill head, there are signs of the drill bit and hammer. When the pointer of the wither ring is adjusted to the direction of 'drill bit', the moving clutch is supported and separated from the static clutch. At this time, the gear directly drives the drill bit for a single rotary motion. When the pointer of the adjustment ring is adjusted to the direction of the 'hammer', the moving clutch is put down and contacts the static clutch. When the impact electric drill street wheel rotates, the impact surface is generated through the uneven contact surface of the clutch, which is transmitted to the drill bit The impact and rotation are formed. The above is the introduction of the working principle of electric tool impact drill.
