The invention discloses a multidirectional flexible package battery film pressing device. The multidirectional flexible package battery film pressing device comprises a handheld base and an adjustingtransmission mechanism mounted on the handheld base. Meanwhile, a first pressing and fixing plate and a second pressing and fixing plate which are oppositely arranged are mounted on the adjusting transmission mechanism, a fixing shaft is arranged on the bottom face of one end of the first pressing and fixing plate, a rotary base is mounted on the fixing shaft, a lifting screw is mounted on the rotary base, meanwhile, a telescopic rod is mounted on the first pressing and fixing plate, a fixing block is mounted on the lifting screw in a sleeving manner, a minitype hydraulic cylinder is mounted on the fixing block, and meanwhile a film pressing base is mounted at the power end of the minitype hydraulic cylinder. As the two pressing and fixing plates with the adjustable positions are arranged,batteries with different heights are fixed, meanwhile, pressing and rotating are carried out simultaneously through the rotary base, the whole circumferences of the batteries are pressed and flattened, meanwhile, the batteries with different heights are pressed and flattened through the effect of the lifting screw, and the multidirectional flexible package battery film pressing device has universality and can be suitable for batteries with different heights and diameters.
