The invention discloses a dustproof electric drill with a charging device. The dustproof electric drill comprises an electric drill body, an output rotating shaft, an electric drill chuck, a drill bitand a handle; the output rotating shaft is arranged at the front end of the electric drill body, and is connected with the electric drill chuck; the electric drill chuck is connected with the drill bit; and the handle is arranged on the drill body. The dustproof electric drill is characterized in that the output rotating shaft is connected with a motor; the motor is positioned in the electric drill body, and is connected with a cell panel in the handle; the cell panel is connected with a plug; a first-grade dust collecting pipe is arranged on the electric drill chuck; a second-grade dust collecting pipe is arranged at the top end of the first-grade dust collecting pipe; and the first-grade dust collecting pipe is movably connected with the second-grade dust collecting pipe. The dustproofelectric drill has the following advantages that under the condition of power failures, standby power in the cell panel can be used to guarantee the work schedule; and the second-grade dust collectingpipe gradually shrinks back along with drilling, so that tight attachment of the second-grade dust collecting pipe and drilled objects is guaranteed, and the dust collecting strength is improved.
