Moving contact mounting structure and ground wire ice-melting grounding device

The invention provides a moving contact mounting structure and a ground wire ice-melting grounding device. The moving contact mounting structure comprises a mounting rack; the first driving part is provided with a switching-on position and a switching-off position, and the first driving part comprises a first elastic piece; the locking structure has a locking state in which the locking structure is in locking fit with the first driving part and an unlocking state in which the locking structure is separated from the first driving part, when the locking structure is in the locking state, the first driving part is located at the switching-on position, and the first elastic piece is compressed, and when the locking structure is in the unlocking state, under the action of the elastic restoring force of the first elastic piece, the first elastic piece is locked. The first driving part quickly moves to an opening position; and the second driving part is provided with an unlocking position for enabling the locking st
