Specifically, as shown in fig. 2 and 4, a groove 220 is formed at an end of the frame 200, one end of the connecting plate 210 extends into the groove 220, and the rotating shaft 230 sequentially passes through one side of the groove 220, one end of the connecting plate 210 and the other side of the groove 220, so that the connecting plate 210 and the frame 200 form a rotating connection, and more horizontal contact surfaces can be formed between the frame 200 and the connecting plate 210 while the rotating connection is realized, so that the load-bearing capacity is better; in order to further improve the bearing capacity, the end of the connecting plate 210 extending into the groove 220 is provided with a cylindrical portion 211, the cylindrical portion 211 is used for accommodating the rotating shaft 230, the upper end and/or the lower end of the cylindrical portion 211 is provided with a flange 212 extending in the horizontal direction, the flange 212 can increase the bearing area, and correspondingly, the side surface area of the groove 220 also needs to be larger than or equal to the area of the upper end/the lower end of the cylindrical portion 211.

As shown in fig. 1, the frame 200 is provided with the accommodating hole 240, so that the frame 200 is in a shape of a square, two sides of the bottom of the accommodating hole 240 are provided with support plates 241 in the shape of angle steel, the support plates 241 extend along two sides of the frame 200, and the two extended support plates 241 and the bottom of the accommodating hole 240 are matched for placing a battery.
