The invention provides a screw pipe set type extensible mechanism and belongs to the technical field of extensible mechanism. The screw pipe set type extensible mechanism comprises a base combination, a driving device combination, extensible screw pipe (4) combinations, an upper top plate combination; each end of a base plate (1) is provided with a screw pipe base (2); a driving pipe (3) is arranged in each screw pipe base (2); each extensible screw pipe (4) combination is arranged in the corresponding driving pipe (3); the upper end of each extensible screw pipe (4) combination is provided with an upper screw (5) and a top plate (7). In the extensible process of the screw pipe set type extensible mechanism, a motor (13) is started to drive the driving pipes (3) to rotate to promote a plurality of extensible screw pipes (4) to extend out one by one, and accordingly the extension process is achieved and the motor (13) rotates reversely and accordingly the retraction of the screw pipe set type extensible mechanism can be achieved according to the same principle. The screw pipe set type extensible mechanism can be matched with a corresponding machine to form a device which is large in vertical lifting distance and horizontal push-pull, simple in structure, smooth and safe and convenient to operate.
