Multi-combination splicing type battery plastic bracket for battery pack and combination splicing method

The invention discloses a multi-combination splicing type battery plastic bracket for a battery pack, which comprises a bracket shell, a central shaft, a battery external interface, a clamping and embedding block, a battery pack clamping and embedding frame and a heat dissipation assembly. During splicing, a core battery is mounted in a slot outer frame, and the electrode end of the core battery is in contact with the bottom of a buckle electrode; the whole battery slot is clamped and embedded in the battery pack clamping and embedding frame, so that the locking buckle is embedded and embedded in the lock catch hole to complete fixation, and meanwhile, the buckle electrode is embedded in the inner side of the bottom end of the contact electrode and is assisted by the auxiliary roller on the inner side of the front end of the buckle clamping plate, so that a frame composed of the whole buckle clamping plate, the vertical plate base and the supporting vertical plate is embedded into the clamping and embedding b
