The present disclosure provides a power tool having a clamping device for a working element. The power tool includes an output shaft, a fastening piece having a flange portion for clamping the working element and a protruding shaft substantially perpendicular to the flange portion. A locking assembly comprising a locking member having a first position in which the protruding shaft is locked and a second position in which the protruding shaft is loosened is provided, wherein a pressing member can press the working element between the pressing member and the flange portion when the locking member is in the first position. The power tool can fasten the working element to the output shaft in a simple and reliable manner without the necessary use of such auxiliary tools as a spanner etc. and can achieve a stronger clamping force even under impact conditions. |
