Abstract
An electrical tool includes a housing, a motor, a bearing set and a shock-absorbing element. The motor is disposed in the housing and has a driving shaft and a nut. The bearing set is arranged on a side of the motor and includes a bearing seat, a bearing and a tool spindle. The tool spindle has a slot disposed at one end thereof facing the motor, and another end thereof is disposed protrusively from the bearing seat. One end of the driving shaft is combined in the slot through the nut. The shock-absorbing element sheathes the nut and is attached to an inner wall of the slot to reduce the vibration and noise during the operation of the electrical tool.
