Swivel Hook Extension/活動勾拉簧
Swivel Hook Extension/活動勾拉簧
A swivel hook extension spring is a type of tension spring equipped with rotating or adjustable hooks at both ends.
This design allows the hooks to rotate freely, preventing the spring from twisting during extension and enabling easier alignment during installation.
Even when the pulling direction changes, it maintains stable and smooth tension performance.
Swivel hook extension springs are widely used in mechanical devices, precision instruments, automotive components, and industrial applications that require flexible connections and adjustable tension.
Features:
Hooks can rotate or adjust angles for greater flexibility.
Prevents torsional stress on the spring body.
Improves service life and installation accuracy.
Suitable for multi-directional tension and space-limited applications.
