For the square lithium battery, the side end faces of the square lithium battery can be adjusted to be parallel to the clamping plates 22 on two sides, and clamping and fixing are realized by the clamping faces 221 of the clamping plates 22 and the two side end faces of the square lithium battery; for the cylindrical lithium battery, through vertically placing the cylindrical lithium battery between the openings of the arc-shaped grooves 222 on the two clamping plates 22, when the clamping plates 22 are close, the clamping and fixing can be realized through the arc-shaped grooves 222 on the clamping surfaces 221 and the side walls of the cylindrical lithium battery. According to the actual clamping requirement, the lithium battery to be clamped is matched with the clamping platform 1 at the corresponding position, so that the lithium battery with various specifications can be clamped without replacing a corresponding special clamp, and the overall production efficiency of the lithium battery is improved.

Alternatively, in a direction parallel to the mounting surface 1a, the clamping surface 221 is provided with a plurality of arc-shaped grooves 222, and the plurality of arc-shaped grooves 222 are arranged at uniform intervals.
