Automatic strengthening pre-twisting processing device

The invention provides an automatic strengthening pre-twisting treatment device, and relates to the technical field of non-cutting treatment of metal energy storage parts. A first fixing assembly of the device is fixed to one end of a supporting piece, the first fixing assembly is connected with a driving assembly, and the first fixing assembly can drive one end of a tested object to rotate so as to perform pre-twisting treatment when the driving assembly is in a working state; the second fixing assembly is in sliding connection with the supporting piece and can fix the end, away from the first fixing assembly, of the tested object; the self-locking speed reducer is connected with the first fixing assembly, the self-locking speed reducer is connected with the magnetic electromagnetic clutch, when the magnetic electromagnetic clutch is in a closed state, the self-locking speed reducer can be in a working state, and when the magnetic electromagnetic clutch is in a separated state, the self-locking speed reducer
