The invention provides a telescopic tube for a safe telescopic heavy mechanical part, and relates to the technical field of telescopic tubes. The telescopic tube comprises the following parts: a telescopic seat tube, a connecting telescopic tube and a tail end telescopic tube, wherein the telescopic seat tube comprises an inner seat tube rotating by external power and an outer seat tube accommodating the inner seat tube; the connecting telescopic tube comprises an inner connecting tube which can be combined with the inner seat tube so as to extend and retract and transmit rotational force, and an outer connecting tube which is connected with an inner hole of the outer seat tube through threads so as to extend and retract; and the tail end telescopic tube comprises a tail end inner tube which can be combined with the inner connecting tube to extend and retract and rotate and a tail end outer tube which is driven by the rotation of the tail end inner tube and is in threaded connection with an inner hole of the outer connecting tube to extend and retract, and the basic conception is that the outer connecting tube is driven by the rotational force of the tail end outer tube subjected to expanding and retracting. According to the telescopic tube, the telescopic seat tubes are arranged, all the telescopic tubes expand and retract in a staged mode through threaded connection, safety can be guaranteed at a high position while heavy mechanical parts are expanded and retracted safely, and the remarkable effect is achieved.
