Special Hook Tension Spring/Tension Spring

  V-shaped German hook extension springs refer to extension springs with hooks at both ends designed in a V shape, originating from Germany, hence called German hooks.Compared to traditional round hooks, the V-shaped hooks provide stronger grip, making the spring less likely to detach under load.  V-shaped German hook extension springs feature a specialized hook shape suitable for unique assemblies where tensile force is applied. When stretched, the spring exerts a counteracting force using its restoring tension.

  Long German hook extension springs are a common type of extension spring featuring long German-style triangular hooks at both ends.This design increases the contact area between the hooks and the fixture under load, enhancing grip and thereby improving the spring’s reliability.  Long German hook extension springs are mostly used in electronic and electrical products. Like other extension springs, they operate by exerting a counteracting force when stretched, utilizing the restoring tension force.

 Short German hook extension springs are a specialized type of extension spring featuring short German-style triangular hooks at both ends.This design enables the spring to provide strong tension within limited space and allows for a more compact installation. The short German hook is compact and robust, making it suitable for applications with restricted space and customizable development according to customer requirements.  The short German hook is ideal when the hook area on the product is small. Like other extension springs, it works by exerting a counteracting force when stretched, utilizing the restoring tension force. 

  Mixed hook extension springs refer to extension springs that combine two or more types of hooks on a single spring.These hooks can differ in shape, size, or even material. This design offers high flexibility and can meet various complex application requirements.

  Swivel hook extension springs are a highly versatile type of extension spring.Unlike standard hooks, the hooks on both ends of a swivel hook extension spring are designed to freely rotate, which greatly enhances the spring’s flexibility and allows it to perform exceptionally well in various specialized equipment.  They are primarily used in mechanical devices, and the main difference from regular hooks is that both ends can rotate, providing added adaptability. Therefore, swivel hook extension springs are considered a highly practical spring type, widely used across many fields due to their flexible nature.  When selecting a swivel hook extension spring, it is important to consider the specific application requirements, taking into account factors such as hook type, material, and dimensions. These factors are often critical and make swivel hook extension springs the preferred choice for many customers.  Swivel hook extension springs are a very practical type of spring, and their flexible characteristics enable them to be widely used in numerous industries. When choosing a swivel hook extension spring, it is essential to comprehensively evaluate the hook design, materials, and dimensions according to the specific application needs.
