1. A fixing structure for a battery pack, the battery pack comprising a box body, the fixing structure being disposed on an outer surface of the box body and comprising:
a first connecting body connected with the box body;
a second connecting body connected with the box body, and the second connecting body being spaced apart from the first connecting body; and
a transition body, the transition body has two ends connected with one end of the first connecting body away from the box body and one end of the second connecting body away from the box body respectively;
wherein the second connecting body defines a plurality of connecting holes;
the transition body defines a through hole;
part of the through hole faces the second connecting body in a direction from the first connecting body to the second connecting body; and
the through hole has a first hole segment and a second hole segment connected in sequence, the first hole segment is located at one side of the second hole segment close to the first connecting body, and a width of the second hole segment is greater than a width of the first hole segment;
the transition body has a first connecting part, a bending part, and a second connecting part connected in sequence;
one end of the first connecting part away from the bending part is connected with the one end of the first connecting body away from the box body;
one end of the second connecting part away from the bending part is connected with the one end of the second connecting body away from the box body;
the first connecting part and the second connecting part define an angle therebetween;
the first connecting part faces the second connecting body;
the through hole extends from the first connecting part to the second connecting part through the bending part; and
the angle between the first connecting part and the second connecting part is an obtuse angle.
