ALIGNMENT ADJUSTMENT MECHANISM

Provided in the embodiments of the present application is an alignment adjustment mechanism used for performing alignment adjustment on a plurality of assemblies. The alignment adjustment mechanism comprises a connecting rod, which extends in a first direction; and at least two clamping jaws, which are arranged on the connecting rod at intervals in the first direction. Each clamping jaw comprises a main body portion, which extends in a second direction, the first direction being perpendicular to the second direction; and clamping portions, which are arranged on the main body portion in a spaced manner in the second direction to form a clamping space, wherein the clamping portions can move in the second direction to adjust the size of the clamping space in the second direction, so as to realize alignment adjustment of the assemblies. The alignment adjustment mechanism can perform alignment adjustment on battery cells and related assemblies during arrangement and assembly of the battery cells and the related as
