Abstract
A wire follow-up protection structure of an electric reducer includes a deformation mechanism with a variable length and sliding plates, the sliding plates being symmetrically disposed on both sides of the deformation mechanism, the deformation mechanism being supported on the sliding plates, the sliding plates limiting the deformation mechanism such that the deformation mechanism deforms between the sliding plates, a continuous run-through channel being preset within the deformation mechanism, the deformation mechanism being disposed to be rotationally connected to the electric reducer and slidably connected to a main body of a coring device, the channel being disposed as a passage for wire.
