Abstract

The disclosure relates to a power tool with a quick-operated locking mechanism. The power tool comprises a housing, an output shaft configured to mount and drive a working head and provided with a carrier extending out of the housing, a fixer configured to fix the working head at the carrier of the output shaft, a locking mechanism configured to lock or release the fixer and a driving mechanism configured to move the locking mechanism between a locking position and a releasing position. While in the locking position, the fixer is clamped fixedly on the output shaft, and while in the releasing position, the fixer is released from the output shaft. The distance between the locking mechanism and the carrier of the output shaft keeps the fixer constant in the locking position to prevent slippage of the fixer and to ensure the working head is firmly fixed.
