The invention provides an auxiliary lifting device. The auxiliary lifting device comprises a first support frame, a second support frame, a turntable, a first moving block, a second moving block, a screw rod, a bearing piece, a hook, a first connecting piece and a second connecting piece. The screw rod is rotationally connected with the first support frame through a bearing, and the screw rod is rotationally connected with the second support frame through a bearing. A first thread and a second thread are arranged on the screw rod, and the rotating direction of the first thread is opposite to that of the second thread. The first moving block is in threaded connection with the first thread, and the second moving block is in threaded connection with the second thread. One end of the first connecting piece is rotationally connected to the bottom of the first moving block, and the other end of the first connecting piece is rotationally connected with the bearing piece. One end of the secondconnecting piece is rotationally connected with the bottom of the second moving block, and the other end of the second connecting piece is rotationally connected with the bearing piece. The turntableis arranged at the end of the screw rod and further fixedly connected with the screw rod. By adopting the scheme provided by the invention, the structure is a pure mechanical structure, the structureis simple, and the use is made convenient. A power source does not need to be carried when being used outdoors.
