Wing-shaped spring and irregularly-shaped wire harness fixing clamp

The utility model provides a wing-shaped spring. The wing-shaped spring includes a connection part, a wing-shaped elastic part including two mutually-symmetrical wing-shaped components formed by extending outward from end parts of two connection arms and a clamping part including two mutually-parallel clamping arms formed by extending from an end part of the wing-shaped elastic part in the direction of a curved board and arranged in parallel with the central axis of the curved board. The utility model provides an irregularly-shaped wire harness fixing clamp including the wing-shaped spring. The wing-shaped spring provided by the utility model is ingenious in structure, reasonable in design and easy to dismount and install. The metal plate pieces with different thicknesses can be clamped firmly on a basis of not damaging the metal plate pieces and other components. The irregularly-shaped wire harness fixing clamp provided by the utility model solves a problem of wire harness arrangement on the peripheries of the metal plates successfully.
