1. An electric shift actuator, comprising a case body assembly, a case cover assembly covering the case body assembly, and a gear reduction mechanism assembly arranged in the case body assembly, wherein the gear reduction mechanism assembly comprises a motor subassembly, a face gear set, a first-stage gear reduction subassembly, and an output gear assembly, wherein the output gear assembly is configured to be connected to a parking mechanism, an output of the motor subassembly meshes with an input of the first-stage gear reduction subassembly in parallel to form first-stage gear reduction transmission, an output of the first-stage gear reduction subassembly vertically meshes with an input of the face gear set to form second-stage gear reduction transmission, and an output of the face gear set meshes with an input of the output gear assembly in parallel to form a third-stage gear reduction transmission structure.
