The invention discloses a deflecting constant-force speed limiter which comprises a base, a first side plate and a second side plate. The first side plate and the second side plate are perpendicularly fixed to the base and are parallel. A rope wheel shaft is assembled between the first side plate and the second side plate and matches the first side plate and the second side plate through a bearing. The rope wheel shaft rotatably matches a rope wheel through a second bearing, and a steel wire rope is wound around the rope wheel. A centrifugal connecting rod amplifying mechanism is arranged on the rope wheel, and hinged to a deflecting amplifying mechanism, and the deflecting amplifying mechanism is rotatably assembled on the rope wheel shaft. The deflecting amplifying mechanism is in linkage with a regulating mechanism, and the regulating mechanism can move in the axial direction of the rope wheel shaft. The lower portions of two convex lugs of the regulating mechanism abut against the upper end of a trigger mechanism, the lower end of the trigger mechanism is hinged to a clamping mechanism, and the clamping mechanism can clamp the rope wheel or the steel wire rope after acting. The deflecting constant-force speed limiter is short in high-low-speed trigger response time, obvious in centrifugal force amplifying effect and stable in overspeed detection and control, and relatively-constant lifting force can be generated.
