The structure of fixing the connector of the battery 21 by the fixing member 232 is more secure than the screw fixing method in the prior art.

It can be understood that the abutting portion 2321 is made of a hard material, and the buckling portion 2322 is made of an elastic material. Specifically, the abutting portion 2321 is a steel plate with high structural strength, which can provide the second connecting member 231b with a high pressing strength when it abuts on the second connecting member 231b, and is not easily deformed. The entire buckle portion 2322 is made of elastic materials such as rubber or silicone, so that the entire buckle portion 2322 can be stretched. The natural deformation length of the buckle portion 2322 is smaller than the distance between the abutting portion 2321 and the main board 1 . , so that when the buckling portion 2322 is buckled on the main board 1 , it exerts a tensile force on the abutting portion 2321 , so that the abutting portion 2321 can fasten the second connecting piece 231b to the first connecting piece 231a tightly.
