Claim 0:
1. An electric drill, comprising:
a housing;
a motor, used for driving the electric drill to work;
an output assembly, used for outputting power of the motor, including:
a transmission shaft, and
an output shaft, wherein the transmission shaft and the output shaft are arranged in parallel, and the transmission shaft is connected with the motor and outputs the power through the output shaft;

a first brake assembly, including:
a driving disc, and
a driven disc, wherein the driving disc and the driven disc are respectively arranged on the transmission shaft and the output shaft, the driving disc is engaged with the driven disc to transmit power in a non-braking state, and the driving disc and the driven disc are displaced in the axial direction to be separated from each other in a braking state to stop transmitting power; and

a second brake assembly, including:
a mass block,
a micro switch connected with the motor, wherein in the braking state, the mass block displaces and triggers the micro switch to stop the motor,
an elastic element of the second brake assembly disposed between the micro switch and the mass block, and
a brake box for receiving the micro switch, the elastic element of the second brake assembly, and the mass, wherein

the mass block is horizontally disposed in the brake box such that the displacement of the mass block is in a horizontal direction, and the brake box is disposed in the housing.
