When the battery 300 is reversely mounted to the battery box unit, referring to fig. 4, the battery negative electrode boss 320 is blocked by the limiting hole 111 to form a gap with the positive electrode connecting piece 120, so that the positive electrode connecting piece 120 cannot be contacted, and the battery negative electrode cannot be conducted with the positive electrode connecting piece 120, thereby preventing the damage of conducting after the battery 300 is reversely mounted.
Further, referring to fig. 3, the positive electrode connecting piece 120 is disposed at the position opposite to the limiting hole 111 of the positive end limiting baffle 110, so that the positive electrode boss 310 of the battery can be in good contact with the positive electrode connecting piece 120 for conducting electricity after the battery 300 is mounted to the battery box unit.
In an alternative manner of this embodiment, the battery box unit negative terminal 200 is provided with a negative terminal limit baffle 220, and the negative terminal limit baffle 220 encloses a mounting groove 210.
