Specifically, the snap-fit ​​hole 7216 may be provided on the extension wall 721a and located near the entrance / exit 7211. The connecting structure may include a movable snap-fit ​​7232, which is rotatably connected to the fixing cover 722 and extends from the fixing cover 722 into the fixing frame 721. It can penetrate into the accommodating space 7210 and engage with the snap-fit ​​hole 7216. The movable snap-fit ​​7232 may be provided in a one-to-one correspondence with the snap-fit ​​hole 7216. One end of the movable snap-fit ​​7232 may be rotatably connected to one side of the cover portion 722b, and the other end may pass through the insert portion 722a. When the fixing cover 722 is closed with the opening 11, the movable snap-fit ​​7232 can penetrate into the accommodating space 7210 and engage with the snap-fit ​​hole 7216. In this embodiment, the connecting structure 723 may further include a rotating shaft 7233 and an elastic element 7234. The rotating shaft 7233 can connect the movable buckle 7232 and the fixed cover 722, so that the movable buckle 7232 can be rotatably disposed. The elastic element 7234 can be disposed in the fixed cover 722, and one end of it protrudes from the cover portion 722b and abuts against the movable buckle 7232, while the other end can abut against the mounting positioning post 7224 of the fixed cover 722. Under no external force, the elastic element 7234 presses the movable buckle 7232, so that the movable buckle 7232 can be fastened to the buckle hole 7216. When the user needs the battery cell 71, the movable buckle 7232 can be pressed horizontally. Under the action of external force, the movable buckle 7232 rotates around the pivot 7233 at a certain angle, so that the movable buckle 7232 is disengaged from the buckle hole 7216. The user can then remove the fixing cover 722 to facilitate the removal of the battery cell 71.
