The invention relates to construction site tools, in particular to a supporting frame with height convenient to adjust for a construction site. The height of the device is convenient to adjust, a top end supporting plate and a tool needing to be supported are always horizontal, and therefore supporting of the device is not affected. The upper ends of connecting rods are connected with a base, the lower ends of the connecting rods are connected with connecting pieces, the upper ends of universal wheel supports are connected with the connecting pieces, and the lower ends of the universal wheel supports are connected with universal wheels. The upper ends of hydraulic cylinders are connected with the base, and the lower ends of the hydraulic cylinders are connected with flat plates. An electromagnetic valve, a control chip and a battery are all arranged in the base. A top plate is installed on the base and located at the top end of the base, and a control panel is installed on the top plate. The lower end of a supporting frame body is connected with the top plate, the upper end of the supporting frame body is connected with an external member, the external member is movably connected with a rotary piece, and the top end supporting plate is installed on the rotary piece.
