It includes a frame 1, with limit shafts 2 fixedly installed on both sides of the end surface of the frame 1, and a side plate 3 fixedly installed on the end of the limit shaft 2 away from the frame 1. The bottom end of the side plate 3 is rotatably connected to a lead shaft 4, which is rotatably connected to the frame 1. The outer surface of the lead shaft 4 and the limit shaft 2 is slidably connected to a bending frame 5. The interior of the bending frame 5 is fixedly installed and spliced ​​to form an extrusion rubber block 6 for extruding the battery. An extrusion plate 7 is provided between the side plate 3 and the bending frame 5. The extrusion plate 7 is slidably connected to the limit shaft 2 and is threadedly connected to the lead shaft 4. The surface of the side plate 3 is provided with a self-locking drive mechanism 8 for driving the lead shaft 4 to rotate.

[0026] Load-bearing grooves 9 are provided on both sides of the end face of the bending frame 5. Adjacent load-bearing grooves 9 are fixedly connected by return springs 10. A guide rod 11 is fixedly installed on the inner ring of the return spring 10. The guide rod 11 is fixedly connected to the frame 1 and the side plate 3. The bending frame 5 is slidably connected to the guide rod 11. This arrangement can ensure that the bending frame 5 can automatically unfold during the loosening process.

[0027] The self-locking drive mechanism 8 includes a driven gear 801, which is fixedly connected to the lead shaft 4. The surface of the side plate 3 is rotatably connected to a driving gear 802 that meshes with the driven gear 801. A worm gear 803 is fixedly installed on the front end of the driving gear 802. A worm 804 is meshed above the worm gear 803. The worm 804 is rotatably connected to the side plate 3. Through such an arrangement, the lead shaft 4 can be rotated, and it can be ensured that the lead shaft 4 can only rotate under the action of external force.

[0028] The surface of the worm 804 is rotatably connected to a limit ring 805, which is fixedly connected to the side plate 3. A plug connector 806 is fixedly installed on the end face of the worm 804. This arrangement makes it easy for an external power source to drive the worm 804 to rotate.

[0029] A wrapping sleeve 12 is provided above the frame 1, and a rubber pad 13 is provided inside the wrapping sleeve 12 for contacting and squeezing the battery. This arrangement enables the battery to be fixed from above after the upper end wire is connected.

[0033] Working principle: Place the battery in the cavity formed by the adjacent extruded rubber blocks 6, and drive the worm wheel 803 to rotate by rotating the worm 804, so that the lead shaft 4 can be driven to rotate by gear transmission, and then the extrusion plate 7 can be driven to extrude the bending frame 5, so that the extruded rubber block 6 can be squeezed with the battery to prevent the battery from rotating itself. After the processing is completed, the battery pack is pushed upward from the bottom to the wrapping sleeve 12 by the push rod 16, so that the bottom can be flipped over for connection. After the connection is completed, the battery pack is pushed out as a whole by the push rod 16.
