The invention discloses a constant force speed governor. The constant force speed governor comprises a bottom board, two side boards, a centrifugal trigger block mechanism, a clamping trigger mechanism, a clamping mechanism and a reset mechanism, wherein the two side boards are fixedly mounted on the bottom board; a sheave shaft is mounted between the two side boards; the sheave shaft is rotationally matched with a rope sheave; a steel wire rope winds through an outer ring of the rope sheave; the centrifugal trigger mechanism is arranged on the rope sheave; the sheave shaft is rotationally matched with a trigger plate; when the speed of the rope sheave is excessively high, the centrifugal trigger block mechanism drives the trigger plate to rotate through friction force; the trigger plate fixes a trigger pin; the trigger pin is hooked to the clamping trigger mechanism; the trigger pin is separated from the clamping trigger mechanism after the trigger plate rotates; the clamping trigger mechanism is mounted on the two side boards in a vertical sliding mode; the clamping trigger mechanism is connected with the clamping mechanism to achieve linkage; the clamping mechanism is mounted on the bottom board; the steel wire rope vertically penetrates through the clamping mechanism and the bottom board; after the trigger pin is separated from the clamping trigger mechanism, the clamping trigger mechanism drives the clamping mechanism to move so as to clamp the steel wire rope, and the steel wire rope clamped by the clamping mechanism is loosened by the aid of the reset mechanism.
