摘要： Disclosed is a power tool which includes a housing, a motor, an output shaft, a working head, a transmission assembly, an auxiliary handle, and a vibration damping assembly. The housing is formed with a main handle configured for being held by a user. The motor is arranged inside the housing and includes a driving shaft. The working head includes an output shaft and an abrasive disc connected to the output shaft, and the output shaft is driven by the motor. The auxiliary handle includes a front end mounted at a position of the housing adjacent to the working head, and further includes a gripping portion extending along a center line. The vibration damping assembly includes a mass member and an elastic element. The auxiliary handle further includes an end cap arranged at a rear end of the gripping portion where the rear end is far away from the housing relative to a front end of the gripping portion. An accommodating cavity for accommodating the vibration damping assembly is formed around the gripping portion when the end cap is combined with the gripping portion. The elastic element is arranged between the mass member and a cavity wall of the accommodating cavity, and a ratio of a natural frequency W1 of the vibration damping assembly to a rotation frequency W2 of the output shaft in rotation is greater than or equal to 0.7 and less than or equal to 1.3. The power tool achieves a desirable vibration damping effect.

摘要： Provided is a battery pack of a power tool. The battery pack of a power tool includes a plurality of cells connected in series; a controller, which is configured to detect a charge current and/or a discharge current of the plurality of cells, estimate remaining capacity of the plurality of cells at least base on an integral of the charge current and/or the discharge current of the plurality of cells over time and generate or select a power supply capability parameter for limiting power of the power tool at least base on the remaining capacity of the plurality of cells; and a memory, which is configured to store data related to the remaining capacity of the plurality of cells. The present disclosure has the advantage of being capable of effectively managing the power of the battery pack during the charging or discharging process, thereby avoiding the overcharge and over discharge of the battery pack and effectively exerting the performance of the battery pack while the safety is ensured.
