The traditional three-side long tail clip has been upgraded to four-side long tail clip. With a longer, smoother finger handle and also maintained with the old long tail clip's firm clamping force, it has significantly improved the disadvantage of excessive load when pressing the handle. And the four-side long tail clip can save 50% of the lever force. The long tail clip is integrated with the hook. The long tail clip is widely used. It has adopted the lever principle and moves the bearing point forward, saving more effort than the traditional one. It can be used in combination with hooks while maintaining the function of the traditional long tail clip. Based on the above two kinds of ideas, we have developed a perfect shape combining clip and hook, upgrading product construction and styling. Quadrilateral long tail clamp body distributes a more uniform load, solving the disadvantage of finger pain when users are using the clip. We have designed different clips based on different sizes on the market. By making a new stress point at the turning point of the quadrilateral long tail clip, we save the cost. At the same time, users can use it more gracefully. This design solves the disadvantage and upgrades the product functionality, Suitable for turning pages, 13% less material, four sizes available to choose which can be labeled for better classification.
