摘要： A percussion tool comprises a housing, an electric motor positioned within the housing, a percussion mechanism driven by the electric motor and including a striker supported for reciprocation in the housing, a battery pack removably coupled to the housing for providing power to the electric motor when coupled to the housing, and an electronic controller including an electronic processor and a memory. The electronic controller is coupled to the electric motor and configured to activate the motor and determine whether the percussion tool is in a loaded condition. In response to determining that the percussion tool is in the loaded condition, the electronic controller is configured to operate the motor in accordance with a predetermined profile and in response to determining that the percussion tool is in a no load condition, the electronic controller is configured to operate the motor at a no-load speed.

摘要： It is an object of the invention to provide an improved technique for lessening an impact force caused by rebound of a tool bit after the striking movement of the tool bit. Representative impact power tool (101) includes a tool body (103), a hammer actuating member (119, 145), a driving mechanism (113, 115), a weight (163) and an elastic element (165). A reaction force that the hammer actuating member receives from the workpiece when performing a hammering operation is transmitted from the hammer actuating member to the weight (163) and then, the weight (163) is caused to move rearward to push the elastic element (165). As a result, the reaction force can be absorbed by the elastic element (165). The elastic force of the elastic element (165) is prevented from acting upon the weight (163) forward beyond the reaction force transmitting position.
