Abstract
A multi-mode drill includes a housing, a motor and a transmission mechanism, wherein the motor and the transmission mechanism are received in the housing. The transmission mechanism has a gear reduction component and a main shaft, wherein the gear reduction component is driven by the motor, and the main shaft is connected with the gear reduction component and driven by the gear reduction component to rotate. The multi-mode drill further includes a mode switching mechanism for causing the transmission mechanism to operate in different modes. The mode switching mechanism includes an operation member and an actuator. The actuator is actuated by the operation member and engages with the transmission mechanism. At least an elastic energy storage member is arranged between the operation member and the actuator.
