The invention discloses an elastic electric conduction device. Under effects of a deformation mechanism, the elastic electric conduction device can change to a deformation position from an elastic recovery position. The elastic electric conduction device comprises at least one electric conduction unit having an elastic bar which can bend and elastically reset. The electric conduction unit is also provided with an acting end and an electric conduction assembly, the acting end can bend in an arc manner under action of the deformation mechanism, the electric conduction assembly is mounted on the elastic bar and is electrically conductive, the electric conduction assembly is applied to a lamp, and utilization scope of the clamp can be expanded. Due to the sheet-shaped structure of the elastic electric conduction device, the beneficial effects of the elastic electric conduction device are that no big space is occupied when the elastic electric conduction device is put away, the elastic electric conduction device is convenient to store and easy to carry, and other effects.
