Description

Technical Field

[0001] The utility model relates to the technical field of spring tension detection devices, in particular to a spring tension detection device. Background Art

[0002] A spring is a mechanical component that utilizes elasticity to function. Parts made of elastic materials deform under external forces and return to their original shape when the force is removed. Springs are typically tested for tensile strength before leaving the factory. This is typically done using a tensile testing device used in spring production, typically after the spring is secured and used.

[0003] However, conventional tension testing devices used in spring production suffer from poor fixing safety and low testing efficiency during use. The spring can easily become dislodged due to excessive tension during testing, and sudden contraction due to the spring's characteristics can easily cause injury to the tester. To overcome these disadvantages, the present invention provides a spring tension testing device. Utility Model Content
