Zusammenfassung:	The utility model relates to a controller with an extending function. The controller comprises a pipe body; the pipe body sequentially comprises an outer threaded pipe, an inner threaded pipe and a limit pipe, wherein, the outer threaded pipe, the inner threaded pipe and the limit pipe are matched with each other; externally convex threads are formed on the pipe wall of one inward end of the outer threaded pipe; internally concave threads are formed on the pipe wall of one outward end of the inner threaded pipe; an internally concave ring is circumferentially arranged on a pipe wall of an inward end of the inner threaded pipe; at least two convex limit blocks which are matched with the internally concave ring on the inner threaded pipe are circumferentially and uniformly arranged on the pipe wall of one inward end of the limit pipe; and an extending control component, which movably penetrates between the outer threaded pipe and the limit pipe, comprises a center connecting pipe, a small pipe sleeve, a connect
