The first battery B1 includes a first positive terminal B1+ and a first negative terminal B1 ", the second battery B2 includes a second positive terminal B2+ and a second negative terminal B2", the first positive terminal B1+, the second positive terminal B2+, the second negative terminal B2-and the first negative terminal B1-are all fixedly disposed, and the third conductive connecting member 16 is movably disposed and rotatably disposed in the battery pack 100.
Specifically, the first positive terminal B1+ and the second negative terminal B2-are respectively provided with a first inserting portion C1 and a second inserting portion C2 from bottom to top along the height direction of the first positive terminal and the second negative terminal. The third conductive connecting member 16 is rotatably disposed in the battery pack 100 above the second positive terminal B2+ and the first negative terminal B1-for controlling the connection or disconnection of the second positive terminal B2+ and the first negative terminal B1-.
