Specifically, the limiting member 2 in the present embodiment includes a limiting portion 21 and a connecting portion 22. Wherein, the limiting part 21 is connected to the battery bracket 3 through the connecting part 22, and the limiting part 21 is located at the outer position of the mounting part 11 relative to the battery bracket 3. The connecting portions 22 are located on two sides of the positioning member 1, and two horizontally extending ends of the limiting portion 21 are respectively connected to the connecting portions 22 located on two sides of the positioning member 1, so that the connecting firmness of the connecting portions 22 to the limiting portion 21 is improved.
