Therefore, in the utility model, the driving rod is set to be in the shape of an elongated strip, which can reduce the size of the through hole and avoid the battery slurry in the mixing drum from leaving the mixing drum through the adjustable stirring assembly, resulting in waste of battery slurry.

[0010] Preferably, the bottom of the turntable is a rotating shaft driven by a driving motor, a driven gear is sleeved on the rotating shaft, the driving motor is connected to a reduction box, the reduction box is connected to a driving gear, and the driving gear is meshed with the driven gear.
