Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of spring processing, in particular to a spring limiter. Background Art
[0002] A spring is a mechanical part that uses elasticity to work. Parts made of elastic materials deform under the action of external forces and return to their original shape after the external force is removed. They are generally made of spring steel. There are many types of springs. According to their shapes, they mainly include helical springs, scroll springs, leaf springs, special-shaped springs, etc. During the spring processing, in order to prevent the spring from moving, a limiter is usually used to fix the spring. When the limiter is used, it is generally used to clamp and fix springs of fixed sizes. It is not convenient to fix springs of different sizes. Therefore, a spring limiter is proposed to facilitate the fixation of springs of different sizes. Utility Model Content
