The invention provides a rapid lifting device which comprises a lifting sleeve, a pulling rod, a supporting shaft, a fist lifting rod and a second lifting rod. The pulling rod is mounted at the top end of the lifting sleeve which is provided with an opening and downwards penetrates through a connecting groove in the outer wall of the lifting sleeve in the radial direction. Connecting holes are symmetrically formed in the lower ends of the two side walls of the connecting groove. The top ends of the first lifting rod and the second lifting rod are ratably connected. Two opposite side faces of the first lifting rod and the second lifting rod are symmetrically provided with open slopes with the top shallow and the bottom deep. The supporting shaft is arranged between the two open slopes and fixed to the lifting sleeve through the two connecting holes. The bottoms of the first lifting rod and the second lifting rod are symmetrically provided with semicircular convex flanges. The rapid lifting device has the beneficial effects that a lifting hole is hooked through the two matched lifting rod end convex flanges capable of changing the sizes along with the hole, and operation is convenient, fast, flexible, safe and reliable.
