A tension spring is an elastic element that can stretch axially under external force and recover its original length after removing the external force. Its core relies on the elastic deformation of spring wires to store and release energy, widely adapting to the force control requirements of stretching scenarios. It is commonly used in fields such as medical devices, automotive parts, and daily necessities, and its specifications need to be customized according to the required stretching length and load-bearing capacity.
