Abstract
Description
Technical Field
[0001] This utility model relates to the field of stationery technology, and more specifically to a lever clip. Background Technology
[0002] Drawer clips are a common office stationery item, mainly used for organizing and storing documents, papers, and other items. They are widely used in schools, offices, homes, and other places, and play a significant role in the classification, storage, and organization of various documents and other paper products.
[0003] The lever clip consists of a plastic cover and vertical levers. To use it, first categorize the documents. Then, pull the lever out from one end of the cover, open the cover, align the left sides of all documents, and place them against the left edge of the cover's clip. Finally, insert the lever back into the cover from the top or bottom. Using the lever clip eliminates the need for punching or binding; simply pulling and moving the lever secures and retrieves documents, and it is reusable.
[0004] like Figure 1 The image shows the structure of the vertical bar of a common drawer clip. This type of vertical bar has a triangular structure. During use, it uses the deformation of the spine to generate elasticity to hold documents and papers in place. The contact point between the vertical bar and the plastic surface is relatively sharp, and there is a risk of scratching the plastic surface when inserting the drawer. After storing thicker documents, the rebound performance of the drawer is poor, and it can no longer be used to store a small number of documents. Utility Model Content

[0021] like Figure 1 As shown, this application discloses a lever clip including a vertical rod and a cover (not shown). The cover can be plastic or other durable materials. The vertical rod is generally made of plastic, but can also be made of other durable and elastic materials.
[0022] The vertical rod includes a spine 1, with a first clamping wall 2 and a second clamping wall 3 connected to both sides of the spine 1. The spine 1, the first clamping wall 2, and the second clamping wall 3 are integrally formed, and an extrusion groove 4 is formed between the spine 1, the first clamping wall 2, and the second clamping wall 3. The thickness of the first clamping wall 2 and the thickness of the second clamping wall 3 gradually increase from the guide opening 5 towards the spine 1.
[0023] The first clamping wall 2 has a first guide portion 201 on the side away from the spine 1. The first guide portion 201 is an arc-shaped convex surface and is formed by bending one side of the first clamping wall 2. The thickness of the first guide portion 201 is greater than the thickness of one side of the first clamping wall 2. The second clamping wall 3 has a second guide portion 301 on the side away from the spine 1. The second guide portion 301 is an arc-shaped convex surface and is formed by bending one side of the second clamping wall 3. The thickness of the second guide portion 301 is greater than the thickness of one side of the second clamping wall 3. A guide opening 5 is formed between the first guide portion 201 and the second guide portion 301. The guide opening 5 is a flared opening.
[0024] The inner sides of the first clamping wall 2 and the second clamping wall 3 are respectively provided with a first anti-detachment rib 202 and a second anti-detachment rib 302. Both the first anti-detachment rib 202 and the second anti-detachment rib 302 are elongated strips, and are arranged along the length directions of the first clamping wall 2 and the second clamping wall 3, respectively. The first anti-detachment rib 202 and the second anti-detachment rib 302 are symmetrically arranged along the center plane of the extrusion groove 4.
