The invention discloses an iron tower portable lifting appliance which comprises a hanging point main body and a hanging point lock hook. A downward bent part is formed at the upper end of the hanging point main body so as to form a hanging point clamping groove with a downward opening; the hanging point clamping groove is correspondingly matched with a vertical part on angle iron; and the hanging point lock hook is of a Z-shaped structure formed by sequentially and fixedly connecting a left vertical section, a middle connecting section and a right vertical section, wherein the lower end of the left vertical section is rotationally connected with the lower end of the hanging point main body, and a hanging hole is formed at the rotating connecting point of the left vertical section and the hanging point main body; a group of adjusting holes are formed at the connecting part of the left vertical section and the middle connecting section; the hanging point main body is provided with positioning holes corresponding to the adjusting holes; one adjusting hole and the corresponding positioning hole are detachably connected with a pin shaft; the end part of the right vertical section is bent leftwards to form a lock hook clamping groove; and the lock hook clamping groove is correspondingly matched with the horizontal part of the angle iron. According to the invention, the opening degree of the lock hook can be flexibly and rapidly adjusted according to the angle iron on iron towers with different specifications, and the angle iron is rapidly locked and is prevented from slipping.
