Fixing mechanism of multi-section battery module

The utility model provides a fixing mechanism for a multi-section battery module, which comprises a plurality of battery fixing frames, and each group of battery fixing frames respectively comprises a first fixing unit and a second fixing unit. The outer surface of the first fixing unit is provided with a concave part which is provided with a first through hole, and the outer surface of the second fixing unit is provided with a corresponding convex part which is provided with a second through hole. And when the first fixing unit is connected with another second fixing unit, the convex part of the second fixing unit is inserted into the concave part of the first fixing unit, so that the front rod body and the rear rod body respectively penetrate through the first through hole of the corresponding first fixing unit and the second through hole of the corresponding second fixing unit so as to be locked on a nut. 本实用新型提供一种多节电池模块的固定机构，包括复数个电池固定架，其中每一组电池固定架分别包括第一固定单元及第二固定单元。第一固定单元的外表面设置一凹陷部且凹陷部设置一第一穿孔，而第二固定单元的外表面则设置
