摘要： This disclosure describes a power tool comprising a housing, a motor received in the housing and an output shaft driven by the motor and used for mounting a cutting tool. The housing comprises a first head housing and a second head housing. The first head housing is used for receiving part of the output shaft. A maximal length of the first head housing along an axial direction of the output shaft is L. A plane where the axis of the output shaft is positioned is defined as a middle plane. N vibration damping elements are disposed between the first head housing and the second head housing and, on at least one side of the middle plane, each vibration damping element comprises a vibration damping part contacting with the first head housing and the second head housing. A sum of the lengths of the N vibration damping parts along the axial direction of the output shaft is larger than or equal to 0.2L and smaller than or equal to L. Therefore, a better vibration damping effect is achieved while working efficiency is not affected.

摘要： The invention 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 constant in the locking position to prevent slippage of the fixer and ensure the working head firmly fixed.
