Description

Technical Field

[0001] This utility model relates to the field of stationery, and more specifically, to an easy-open lever clip. Background Technology

[0002] A lever clip is a stationery item that uses a lever to hold pages together. Lever clips are usually made of plastic or metal, are lightweight and durable, and are typically used with book covers.

[0003] A lever clip typically includes a connecting part and two symmetrically arranged clamping wings. A clamping opening is formed between the two clamping wings. In use, the book page is passed through the clamping opening, so that the two clamping wings press against the sides of the book page, thus completing the lever clip's clamping of the book page.

[0004] To ensure gripping of thinner pages, existing lever clips typically have small openings. This makes it inconvenient to use fingers to pry open the two gripping wings to widen the opening when gripping thicker pages.

[0005] Therefore, a new solution is needed to address this problem. Utility Model Content

[0006] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide an easy-opening rod clamp.

[0007] The above-mentioned technical objective of this utility model is achieved through the following technical solution: an easy-opening lever clamp, including a connecting part and two symmetrically arranged clamping wings, the two clamping wings are respectively fixed at both ends of the connecting part, a clamping opening is provided between the two clamping wings, a sliding groove is provided on the outer side wall of the clamping wing that passes through the outer side wall of the connecting part, a lever piece with one end exposed outside the connecting part is slidably connected in the sliding groove, and a limiting member is provided on the clamping wing to restrict the sliding of the lever piece.

[0008] The present invention is further configured such that: a magnetic plate is provided on the lever plate, a plurality of grooves are provided on the side wall of the slide groove, and the limiting member is an iron plate fixed in the groove.

[0009] The present invention is further configured such that: a plurality of deformation grooves are provided on the outer wall of the clamping wing along the length direction, and the groove is connected to a deformation groove provided near the connecting part.

[0010] The present invention is further configured such that: a limiting groove is formed on the two opposite inner walls of the slide, the length of the limiting groove is less than the length of the slide, and the two ends of the lever are provided with ball protrusions that slide in the limiting groove.

[0011] The present invention is further configured such that the groove is opened at the end near the clamping wing.

[0012] The present invention is further configured such that the thickness of the end of the clamping wing away from the connecting part is less than the thickness of the connection between the clamping wing and the connecting part.

[0013] In summary, this utility model has the following beneficial effects:

[0014] When using the lever clamp, release the limiting member from the lever plate and allow part of the lever plate to slide out along the side wall of the slide groove outside the connecting part. At this time, people can squeeze the two lever plates by hand to make the two clamping wings rotate with the connecting part as the lever point, thereby making the clamping opening formed between the two clamping wings larger, making it easier for thicker pages to pass through the clamping opening. Compared with the existing method of prying open the clamping wings with fingers, the above setting makes it more convenient to expand the clamping opening. Attached Figure Description

[0019] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0020] Easy-opening lever clip, such as Figure 1 and Figure 2 As shown, the device includes a connecting part 1 and two symmetrically arranged clamping wings 2. The two clamping wings 2 are fixed to both ends of the connecting part 1, and a clamping opening 3 is provided between the two clamping wings 2. A groove 4 is provided on the outer wall of the clamping wing 2, which passes through the outer wall of the connecting part 1. A lever piece 5 with one end exposed outside the connecting part 1 is slidably connected in the groove 4. A limiting member is provided on the clamping wing 2 to limit the sliding of the lever piece 5. When using the lever clamp, the limiting member is released from the limiting member on the lever piece 5, and part of the lever piece 5 slides out of the connecting part 1 along the side wall of the groove 4. At this time, people can squeeze the two lever pieces 5 by hand to make the two clamping wings 2 rotate with the connecting part 1 as the lever point, thereby making the clamping opening 3 formed between the two clamping wings 2 larger, which makes it easier for thicker pages to pass through the clamping opening 3. Compared with the existing method of prying open the clamping wings 2 with fingers, the above-mentioned setting makes it more convenient to expand the clamping opening 3.

[0021] like Figures 1 to 3As shown, the lever 5 is equipped with a magnetic piece 6, which is located away from the lever 5. Several grooves 7 are formed on the side wall of the slide groove 4. The limiting element is an iron piece 8 fixed in the groove 7. After using the lever 5, it is slid back into the slide groove 4. The magnetic piece 6 adheres to the iron piece 8, and the lever 5 is fully embedded in the slide groove 4, thus completing the storage of the lever 5. This allows the lever 5 to be well-limited by the iron piece 8 during subsequent use of the lever clip, reducing the possibility of accidental slippage. Furthermore, the iron piece 8 also improves the strength of the slide groove 4 on the clamping wing 2 to some extent. Several deformation grooves 9 are formed along the length of the outer wall of the clamping wing 2. This design ensures that when the clamping wing 2 contacts the page... The lever 4 can deform along the deformation groove 9 to increase the contact area between the clamping wing 2 and the page. By increasing the friction between the clamping wing 2 and the page, the possibility of relative sliding between the clamping wing 2 and the page is reduced. The slide 4 is connected to a deformation groove 9 near the connecting part 1. When it is necessary to slide the lever 5, the fingernail can be inserted into the deformation groove 9 and force can be applied to the lever 5 to cause the magnetic piece 6 to disengage from the iron piece 8, making it easy to release the limit of the lever 5. Limiting grooves 10 are opened on the two opposite inner walls of the slide 4. The length of the limiting grooves 10 is less than the length of the slide 4. The limiting grooves 10 are not connected to the outer wall of the connecting part 1. The two ends of the lever 5 are provided with ball protrusions 11 that slide in the limiting grooves 10. Specifically, the lever 5 is made of polycarbonate. Made of ester material, the ball protrusion 11 and the lever piece 5 are integrally formed. The ball protrusion 11, which slides in the limiting groove 10, can effectively prevent the lever piece 5 from completely sliding out of the slide groove 4, making it difficult for the lever piece 5 to detach from the clamping wing 2. When the lever piece 5 is installed on the clamping wing 2, the ball protrusion 11 and the two opposing inner walls of the slide groove 4 can abut and deform, facilitating the installation of the lever piece 5. The slide groove 4 is opened near the end of the clamping wing 2, and there is only one slide groove 4 on a single clamping wing 2. When the lever piece 5 is pressed, the end of the clamping wing 2 is more likely to deform, thereby facilitating the expansion of the clamping opening 3 and making it easier for the book page to be inserted through the clamping opening 3. The above configuration can reduce the opening area of ​​the slide groove 4 on the clamping wing 2, reducing the cost. The low groove 4 affects the strength of the clamping wing 2 itself. The thickness of the end of the clamping wing 2 away from the connecting part 1 is less than the thickness of the connection between the clamping wing 2 and the connecting part 1. This setting makes the end of the clamping wing 2 closer to the page more prone to deformation when the clamping wing 2 comes into contact with the page. Since the connection between the clamping wing 2 and the connecting part 1 is thicker, the connection strength is higher. During long-term use, the connection between the clamping wing 2 and the connecting part 1 is less likely to break, which can improve the service life of the pull rod clip. The connecting part 1 and the clamping wing 2 are both made of polypropylene. The connecting part 1, the clamping wing 2 and the groove 4 are injection molded in one piece. Polypropylene material has good toughness. The pull rod clip made of this material still maintains its original performance after long-term contact with the page.

All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
