A connecting wire 10 is magnetically connected to one end of the magnetic base 4. A connecting plug 11 is fixedly installed on the other end of the connecting wire 10 away from the magnetic base 4. The connecting plug 11 is used for external power supply to the battery 3. By setting the battery 3 to slide inside the device box 2 and allowing the battery 3 to slide out of the device box 2, it is possible to charge the battery 3 separately when it is out of power. At the same time, the connecting wire 10 is magnetically connected to one side of the battery 3 through the magnetic base 4, and a connecting plug 11 is fixedly installed on one end of the connecting wire 10. When the connecting plug 11 is connected to a socket, the battery 3 inside the device box 2 can be charged. Thus, the battery 3 can be either removed for charging separately or charged inside the device box 2 using the connecting wire 10 and the connecting plug 11, meeting the various needs of the user and avoiding a decrease in work efficiency due to the battery 3 being out of power.
