Electrical position-limiting adjusting device

The utility model discloses an electrical position-limiting adjusting device comprising a central shaft, a supporting base, a gland, a first adjusting shaft, a second adjusting shaft, a third adjusting shaft, a fourth adjusting shaft, a first cam, a second cam, a third cam, a fourth cam, a first fixed retainer ring, a second fixed retainer ring, a third fixed retainer ring and a fourth fixed retainer ring. External teeth of the four adjusting shafts are arranged at different heights. The external teeth of the four adjusting shafts and internal teeth of the four cams are engaged. The four cams are mutually position-limited by using the fixed retainer rings so that a time interval of signal switch action and limit switch action can be adjusted. The electrical position-limiting adjusting device is convenient to adjust and continuously adjustable, adjusting time can be saved, and the position-limiting device and an output shaft are surface-contacted instead of point-contacted so that mechanical damage is reduced.
