Description

technical field [0001] The invention relates to a hand-held tool, especially a hand-held tool provided with a battery pack. Background technique [0002] In the existing hand-held tools, in order to free the operator from the inconvenience caused by long power cords, a battery pack is often provided on the hand-held tools to provide power. Generally, the housing of the hand-held tool is arranged in a longitudinal shape, and the working components are located at the front of the housing; the motor is arranged next to the working components and stored in the middle of the housing for holding; the battery pack is arranged at the rear of the motor. This hand-held tool has a compact structure, a small volume, and is relatively flexible, and is suitable for processing some relatively small workpieces. [0003] However, the heaviest part of the tool is usually the working components and the motor. The working components and the motor of this type of hand-held tool are set in the m...
