Of course, a charging port 2012 adapted to other connectors can also be selected, and it is not limited to the type-C connector.

[0030] The circuit board 2013 has a positive piece 20131 and a negative piece 20132, one end of the positive piece 20131 is connected with the circuit board 2013, and the other end extends into the mounting groove 2011; one end of the negative piece 20132 is connected with the circuit board 2013, and the other end extends into the mounting groove 2011; when the battery is inserted, the positive piece 20131 is in conductive connection with the positive electrode of the battery, and the negative piece 20132 is in conductive connection with the negative electrode of the battery, so that the circuit board 2013 is in conduction with the battery.

[0031] Further, the charging sleeve also has a clamping groove 2016, the clamping groove 2016 communicates with the mounting groove 2011, when the battery is inserted into the mounting groove 2011, the positive electrode of the battery is inserted into the clamping groove 2016, so as to improve the stability of the connection between the sleeve body 201 and the battery. In specific application, the clamping groove 2016 communicates with the positive channel 2014, that is, one end of the positive piece 20131 extends into the mounting groove 2011 after passing through the positive channel 2014 and the clamping groove 2016. Preferably, the outer surface of one end of the clamping groove 2016 close to the mounting groove 2011 is provided with a clamping inclined surface 20161, the cross section of the clamping inclined surface 20161 is in inverted "eight" shape, or can be understood as in trumpet shape, wherein the clamping inclined surface 20161 gradually reduces in caliber along the direction close to the mounting groove 2011, so as to improve the clamping effect of the clamping groove 2016 on the positive electrode of the battery.

[0032] In another embodiment, the charging sleeve further has a magnetic piece 2017 located in the clamping groove 2016, and the positive pole piece 20131 is connected with and conducts the magnetic piece 2017.
