1. A winding device, characterized by comprising:
a first inner shaft and a second inner shaft that are arranged opposite to each other and configured to clamp an electrode assembly; and
a first outer shaft and a second outer shaft that are arranged opposite to each other, outer peripheries of the first outer shaft and the second outer shaft being configured to wind the electrode assembly; and, wherein
the winding device further comprises a first slider and a first pusher, wherein the first pusher is fixedly connected to the first inner shaft, the first pusher is provided with a first sliding slot, the first slider is movable in the first sliding slot, the first slider is configured to reciprocate in a first direction, and an extension direction of the first sliding slot is inclined from the first direction such that the first pusher drives the first inner shaft to reciprocate in a second direction so as to clamp or release the electrode assembly, the second direction being perpendicular to the first direction; and
the winding device further comprising a second slider and a second pusher, wherein the second pusher is fixedly connected to the first outer shaft, the second pusher is provided with a second sliding slot, the second slider is movable in the second sliding slot, the second slider is configured to reciprocate in a third direction, and an extension direction of the second sliding slot is inclined from the third direction such that the second pusher drives the first outer shaft to reciprocate in a fourth direction so as to increase or decrease a distance between the first outer shaft and the second outer shaft, the third direction being parallel to the first direction, and the fourth direction being perpendicular to the third direction.
