[0036] It also includes an arc-shaped piece 5, each of which is provided with four detachable arc-shaped pieces 5, and the four arc-shaped pieces 5 are evenly distributed in the placement circular groove 2 4. A plurality of plastic connection points 14 are fixedly connected between the arc-shaped piece 5 and the placement circular groove 2 4, and a plurality of plastic connection points 2 15 are fixedly connected on the side walls of two adjacent arc-shaped pieces 5.

Then, during the use of the connecting piece, the connecting piece is removed from the insertion cylinder 19. During the use of the top bracket 2 and the bottom bracket 1, the insertion cylinder 19 can also be removed from the fixing seat 16 to complete the purpose of installing the battery between the top bracket 2 and the bottom bracket 1.
[0040] A connecting piece is arranged on a battery bracket with a welding short-circuit prevention function. A metal protrusion 21 is arranged on the connecting piece.

Then, the multiple arc-shaped pieces 5 that need to be disassembled in the circular groove 2 4 are determined, and the rotating ring 7 is rotated in the rotating sleeve 6. The position of the disassembly plate 8 is adjusted to move the disassembly plate 8 to the bottom of the corresponding arc-shaped piece 5. When the rotating ring 7 is rotated, the four indicator bars 13 are all moved into the gap between the corresponding two arc-shaped pieces 5, and the side ends of the indicator bars 13 are aligned with the side walls of the arc-shaped piece 5, thereby determining the moving position of the disassembly plate 8. The disassembly plate 8 is positioned, and the disassembly plate 8 is moved upward, so that the insertion seat 11 first squeezes the plastic arc strip 10 to bend upward, and after the arc notch 12 area of the insertion seat 11 enters between the two plastic arc strips 10, the plastic arc strip 10 flips downward and resets, and the plastic arc strip 10 contacts the inner wall of the arc notch 12, so that the disassembly plate 8 and the arc piece 5 are kept in meshing, and the disassembly plate 8 is continued to move upward, so that the plastic connection point 14 and the plastic connection point 2 15 that are connected to the arc piece 5 are torn, so that the arc piece 5 is removed and retained on the disassembly plate 8;
[0043] After completing the disassembly of the arc sheet 5, multiple batteries are placed between the corresponding placement circular grooves 1 3 and 2 4 between the top bracket 2 and the bottom bracket 1, and then the positive electrode segment 26 and the negative electrode segment 24 of the connecting sheet are in contact with the positive and negative electrodes of the battery, and then an electric welder is used to weld the negative electrode segment 24 to the negative electrode of the motor, while the positive electrode segment 26 and the negative electrode are spaced by the arc sheet 5 to avoid short circuit problems during welding.
