Overhead circuit shearing force type strain hardware

The invention discloses an overhead circuit shearing force type strain hardware, comprising a connection sheet and a connection bolt which are connected to an outside lead; the connection sheet and the connection bolt are connected through a connection assembly; the connection assembly comprises a connection member, an elastic member and a protection member; ends of the connection member, the elastic member and the protection member are connected to the connection sheet, and the other ends are connected to the connection bolt; the length of the connection member is equal to the length of the elastic member in the normal state; the protection member is of a telescopic structure; and the maximums stretch length of the protection member is equal to the maximums stretch length of the elastic member. The overhead circuit shearing force type strain hardware can be effectively connected to the two outside leads through the arrangement of the connection member, the connection sheet and the connection bolt, the distance between the connection sheet and the connection bolt is stretched through the arrangement of the elastic member when the strain of the metal exceeds the limit, and the problem that the elastic member can be overly stretched and damaged is prevented through the arrangement of the protection member.
