A safety device comprises a first heat dissipation part, a second heat dissipation part and a connecting part. The connecting part is arranged between the first heat dissipation part and the second heat dissipation part, and at least one heat locking hole disposed thereon. The heat locking hole of the connecting part can reduce a diffusion speed of heat of the connecting part, so that the heat is concentrated between the first heat locking hole and the second heat locking hole, and thus the connecting part can be fused in time at a high temperature.
