[0002] Electric vehicles are mechatronic personal transportation vehicles that use batteries as auxiliary energy sources on the basis of ordinary bicycles and are equipped with motors, controllers, batteries, throttles, brakes and other operating components and display instrument systems. At present, electric vehicles are widely used in people's lives and have replaced many transportation vehicles to become the first choice for people to travel. Electric vehicles are mainly powered by lithium batteries.

[0003] There are still some problems in the use of existing electric vehicle lithium batteries. The lithium batteries inside the electric vehicle need to be disassembled for inspection or replacement after long-term use. However, some lithium batteries are assembled from multiple battery packs, so it is more troublesome to carry them, and they are easy to collide with external objects when carried, causing damage to the battery itself.

[0026] In this embodiment: a base 1 is provided, and a box body 2 is fixedly connected to the top of the base 1. When the lithium battery needs to be carried, the rotating cover 15 is first rotated to drive the screw rod 14 to rotate inside the threaded tube 13, so that it moves downward, and the extrusion rod 16 is driven to move by the movement of the screw rod 14, so that the extrusion rod 16 squeezes the moving block 9 on the outside of the slide bar 7, so that the moving block 9 moves downward on the outside of the connecting plate 5.
