However, most of the existing hand-held charging drill chucks can not be disassembled, which is not easy to replace the chucks quickly, but also makes the charging drill occupy a large space and is not easy to carry. Moreover, the existing hand-held charging drill has a single function, and the handle of charging drill can only be used for drilling At the same time, most of the existing hand-held charging drills are lack of corresponding heat dissipation devices. When the motor is used too long, it is easy to be damaged due to high temperature. Therefore, the research and development of new portable hand-held charging drill has attracted more and more attention of researchers.
