Earth auger

An earth auger, comprising:

• a transmission assembly, arranged on a connecting base;
• a motor assembly, connected with the transmission assembly, and configured to drive the transmission assembly to rotate;
• a controller, arranged at a first side of the transmission assembly, connected with the motor assembly, and configured to control a rotation of the motor assembly through an on-off of a circuit;
• a control knob and a plurality of indicator lights, arranged on a housing, the control knob configured to set critical values of angular velocities of different gears and set critical values of angular accelerations of the different gears, and the indicator lights configured to display a current gear;
• a gyroscope sensor, arranged at a second side of the transmission assembly,
• wherein, the gyroscope sensor is configured to obtain angular velocity information and angular acceleration information during a movement of the earth auger, to feedback a monitored signal to the controller, and when the monitored signal exceeds a preset critical value of the current gear, the controller stops power supply to stop the motor from rotating;
• and
• a bracket, installed with an anti-impact assembly, wherein, the anti-impact assembly comprises:
• a blocking plate,
• a plurality of fastening bolt assemblies, passing through the blocking plate and mounted with the bracket;
• and
• a plurality of buffer components, sleeved on the fastening bolt assembly and located between the blocking plate and the bracket.
