The clamping cylinder 51 comprises a plurality of elastic clamping claws arranged at the flared end 511 and spaced along the circumference of the clamping cylinder 51. The driving cylinder 52 is sleeved outside the clamping cylinder 51 and can move relative to the clamping cylinder 51 along the second direction D2. When moving, the driving cylinder 52 extrudes the elastic clamping claws to clamp and release the shaft 202 of the core 200. The lifting support 20 is provided with a clamping shaft power element 53 capable of driving the driving cylinder 52 to move relative to the clamping cylinder 51 along the second direction D2.
