Key structure

The invention discloses a key structure. A base-plate of the key structure is provided with a key cap, a connecting rod and a restoring component, wherein the key cap is supported by the connecting rod and can move in a first direction corresponding to the base-plate. When the key cap vertically moves corresponding to the base-plate in the first direction, the key cap drives the connecting rod to pivot corresponding to the key cap, and slides on the base-plate in a second direction. The restoring component linked by the connecting rod is further driven by the connecting rod in a horizontal direction and is used for storing elastic restoring force by an elastic member in the restoring component. According to the key structure provided by the invention, the movement of the key cap corresponding to the base-plate in the vertical direction is converted into the movement of driving the restoring component in the horizontal direction by the connecting rod so as to store the elastic restoring force; furthermore, the
