[0038] The working principle of the easily disassembled lithium battery pack provided by this utility model is as follows:

[0039] When installing and removing lithium batteries, the device first places the entire lithium battery structure 2 inside the outer casing assembly 1. After installation, the positioning components 3 at both ends are slidably positioned. The elastic clamping components 4 on the inner wall of the positioning components 3 will make positional contact with the lithium battery structure 2 to reduce rigid contact of the workpiece and prevent surface damage to the lithium battery structure 2. After the workpiece is positioned, the top structure of the outer casing assembly 1 is closed. With continuous positional movement, the positioning components 3 and the elastic clamping components 4 can be positioned and clamped by the mating and squeezing components 5 between the inner walls, thereby ensuring the stability of the position of the lithium battery structure 2. Subsequently, the position of the entire outer casing assembly 1 is locked by the limiting locking components 6 at both ends, which simplifies the entire workpiece installation process and improves the ease of operation of the device.
