referring to FIG. 6, the upper assembly is shown upside down for better illustration of the structure. The upper assembly 2 comprises a first hollow cylinder 21 with an opening at the lower end, a first through hole 22 for extending a first pole of the single battery 1 is arranged on the upper end surface of the first hollow cylinder 21, and a first fixing plate 23 extending outwards is arranged on the upper edge of the first hollow cylinder 21. It should be mentioned that the first fixing plate 23 is square, and when installed, is placed in the corresponding square groove, and cannot rotate.

Similarly, referring to fig. 7, the lower assembly 3 includes a second hollow cylinder 31 with an open upper end, a second through hole 32 for extending a second pole of the battery cell 1 is disposed on a lower end surface of the second hollow cylinder 31, and a second fixing plate 33 extending outward is disposed on a lower edge of the second hollow cylinder 31. The first hollow cylinder 21 and the second hollow cylinder 31 enclose a space for accommodating the unit cells 1.

Referring to fig. 6 and 7, in the present embodiment, the fastening mechanism includes an upper fastening component and a lower fastening component. The upper fastening assembly includes a first hook 231 disposed on the first fixing plate 23 along two sides of the first direction and a first engaging groove 232 disposed on the first fixing plate 23 along two sides of the second direction; the lower fastening assembly includes a second hook 331 disposed on the second fixing plate 33 along two sides of the first direction and a second engaging groove 332 disposed on the second fixing plate 33 along two sides of the second direction; the first direction is perpendicular to the second direction. Taking the first clamping groove 232 as an example, the first clamping groove 232 is an L-shaped groove, a vertical section of the L-shaped groove penetrates through the upper end surface and the lower end surface of the first fixing plate 23, and a horizontal section of the L-shaped groove is arranged on the lower end surface of the first fixing plate 23 and extends from the vertical section to the edge of the first fixing plate; the same applies to the second card slot 332.
