The invention discloses an arc block type lifting rod combination and belongs to the field of construction tools. The combination can be used for manually lifting up and moving a heavy object conveniently and quickly. The combination comprises a pair of circular lifting rods, the lifting rods are longitudinally arranged side by side at certain intervals in the left-right direction, and screw rodswith opposite thread turning directions are transversely connected to the portions, away from the ends by a certain distance, of rod bodies of the lifting rods in a left-right opposite mode correspondingly. A round pipe, namely a nut pipe, is in threaded connection with each screw rod. Threads matched with threads on the left and right screw rods are machined in the inner walls of the round pipescorrespondingly. A section of sleeve sleeves a middle rod body section of each lifting rod in a clearance fit mode, and the outer side surfaces and the inner side surfaces of the walls of the sleevesare fixedly connected with balance weights and arc blocks correspondingly. The design provided by the invention is suitable for construction sites such as stone carving sites.
