The invention discloses a stroke adjusting mechanism for a point switch and a locking rod and an indicating rod comprising the stroke adjusting mechanism and belongs to the field of connecting structures, the stroke adjusting mechanism comprises a screw joint, and a front nut, an adjusting screw sleeve and a rear nut which are in threaded connection with one side of the screw joint in sequence; alimiting protrusion is arranged on the outer wall of one end of the adjusting threaded sleeve. The outer wall of the other end of the adjusting threaded sleeve is in threaded connection with a round nut, the limiting protrusion and the round nut are used for clamping a main rod connector and an auxiliary rod connector in a matched mode, the adjusting threaded sleeve is rotated to drive the auxiliary rod to move to adjust the distance between a main rod notch and an auxiliary rod notch of the point switch, and the front nut and the rear nut are matched to clamp the adjusting threaded sleeve. The stroke adjusting mechanism can be directly connected to the auxiliary locking rod (or the indicating rod) and the locking rod connector (or the indicating rod connector), and it is guaranteed that the original function of the locking rod (or the indicating rod) is not changed; and the adjusting structure of the linkage locking rod is arranged at the joint of the outer rod of the point switch, sothat field observation, inspection and adjustment are facilitated.
