The invention provides an emergency early-warning indication frame which comprises a balance weight base, a plurality of sleeve connection frames connected in a sleeving mode and an early-warning unit. The areas of the cross sections of the sleeve connection frames are increased from inside to outside in a progressive mode. The sleeve connection frame of the inner layer is sleeved with the sleeve connection frame of the outer layer. The side faces of the adjacent sleeve connection frames are connected in a clamped mode after the sleeve connection frames are stretched. The sleeve connection frames are spliced into a cone or a frustum shape after being connected in a clamping mode. The early-warning unit is located on the sleeve connection frames. The emergency early-warning indication frame has the advantages that the structure is telescopic, storage is convenient, and little space is occupied.
