[0046] An arc plate 306 is fixedly installed on one side of the lower end face of the support platform 30. The lower part of the arc plate 306 is provided with an inner plate 304 fixed to the vertical rod 3. A cam 305 is mounted on the inner plate 304 by a motor. The cam 305 is always in contact with the arc plate 306. The motor drives the cam 305 to rotate, thereby achieving intermittent compression of the arc plate 306. When the arc plate 306 is compressed, the support platform 30 can move the battery cell upward along the vertical rod 3 so that the lifting mechanism can pick up the battery cell from the support platform 30.

A pull rope is provided between the retractable and extendable wheels 421, and a lifting plate 41 is installed between the pull ropes on both sides. Two upright plates 4 are fixedly mounted on the base 1, and limit plates 40 are fixedly mounted on the upright plates 4. The two upright plates 4 are slidably connected to the lifting plate 41.

A drive rod 431 is rotatably mounted, with a first half gear 44 fixedly mounted on one side of the drive rod 431 and a second half gear 45 fixedly mounted on the other side. After the battery cell is moved upward by the support platform 30, the electric slider opens, causing the toothed plates 414 on both sides to move away from each other. When the toothed plates 414 slide outward, they drive the ring plate 412 to rotate through the control wheel 415 and the rotating rod 413. At this time, the ring plates 412 on both sides flip towards each other, and the lower part of the ring plate 412 rotates into the corresponding rectangular groove 301. At the same time, the ring plate 412 rotates into the corresponding rectangular groove 301. The lower part of 12 is located at the bottom of the battery cell.
