a packing in a ring shape disposed between the second plate of the first supercapacitor and the first plate of the second supercapacitor.

7. The electronic device of claim 3 , further comprising

a safety cock disposed on the outer wall and discharging gas inside the case to an outside.

8. The electronic device of claim 1 , wherein

the body part includes:

a second docking connector connected to the supercapacitor module through the first docking connector when the body part is combined to the extension pipe;

a power switch disposed to at least one of wires for connecting terminals of the second docking connector and the motor and switching an electrical connection between the second docking connector and the motor; and

a control module for detecting whether the extension pipe is combined to the body part, and controlling the power switch so as to form a current path between the supercapacitor module and the motor when the body part is combined to the extension pipe.

9. The electronic device of claim 8 , wherein

the control module is connected to the second docking connector, and charges the battery module with an output of the supercapacitor module when the body part is combined to the extension pipe.

10. The electronic device of claim 9 , wherein

the control module detects a voltage of the supercapacitor module when the body part is combined to the extension pipe, and it transmits an output of the battery module to the motor when a voltage of the supercapacitor module is equal to or less than a predetermined value.

11. The electronic device of claim 10 , wherein

the control module transmits an output of the battery module to the motor when the combination of the body part and the extension pipe is removed.

12. The electronic device of claim 8 , wherein

the body part further includes a switch for selecting one of the supercapacitor module and the battery module as a power source of the motor, and

the power switch is turned on or turned off according to an operation of the switch.

13. The electronic device of claim 12 , wherein

when the switch is operated to select the supercapacitor module as a power source of the motor, the power switch is turned on by the switch and an output of the supercapacitor module is transmitted to the motor, and
