The paper put forward a kind of mechanism which can output constant-force.The principal of the mechanism was that by designing the profile of the parts, the directions of normals in contact points can be controlled,which made the function relationship between the displacement and the direction of force passed via parts desirable,thus the function relationship between the displacement and the force output met the demands.Further, through an example and the related experiments,the mechanism and the design method were proved to be feasible and effective.
