Description

Technical Field

[0001] This application relates to the field of dovetail clips, and in particular to a novel dovetail clip. Background Technology

[0002] Brush clips are a common tool for daily office and study use, and are widely used for organizing paper documents, binding materials, and temporarily fixing documents.

[0003] However, traditional swallowtail clips use a triangular clip body and two handles. This structure has significant drawbacks when stored: when the handles are closed, the length of the swallowtail clip is the sum of the clip body's length and the clip's length, making it quite long. When the handles are open, the two handles rest against the two inclined surfaces of the clip body. At this point, the furthest distance between the two ends of the handles equals the height of the swallowtail clip, which is 1.5-2.5 times the height of the clip body, making it quite tall. When placed in a pencil case, folder, or pocket, the traditional swallowtail clip's large height or length, regardless of whether the handles are open or closed, results in a larger volume. Furthermore, after clipping a document, the handles need to be folded back, at which point the clip's length is the sum of the clip body's length and the handle's length. This makes the overall length of the swallowtail clip too long, and the handles can interfere with page turning, affecting the viewing experience. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the prior art and provide a new type of dovetail clip.

[0005] To achieve the above objectives, this application adopts the following technical solution:

[0006] A novel dovetail clip includes a clip body and two clip handles. The clip body is formed by bending an elastic sheet to form a ridge and two clips. The ends of the clips are rolled to form a pivot shaft portion. The clip handles have pivot posts. The pivot shaft portion has a first pivot groove and a second pivot groove. The pivot post is located in the first pivot groove or the second pivot groove. The clip body also has a storage groove. When the pivot post is located in the first pivot groove, the clip handle enters the storage groove. When the pivot post is located in the second pivot groove, the clip handle abuts against the surface of the clips. The first pivot groove is farther away from the ridge than the second pivot groove.

[0007] Preferably, the storage slot includes a clearance area formed on the clip and a storage area formed on the spine, and when the clip is located on the bottom wall of the storage area, the farthest distance between the two clips is less than the width of the spine.

[0008] Preferably, the storage area has two sides, which gradually move closer to each other from the position of the storage area and the clearance area to the bottom position of the storage area.

[0009] Preferably, the bottom of the storage area is arc-shaped, and the arc-shaped surface of the clamp is concentrically adapted.

[0010] Preferably, a buffer groove is also connected between the first pivot groove and the second pivot groove, and the spacing of the buffer groove is smaller than the diameter of the pivot post.

[0011] In summary, this utility model has the following beneficial technical effects:

[0012] When the handle is closed, the overall length of the binder clip is the length of the handle minus the length of the clip body. This closed state of the binder clip does not affect the turning and reading of documents. On the other hand, multiple documents clipped by different binders can be stacked, and users can use the handle to quickly pick up documents from different positions. Attached Figure Description

[0018] The directional terms such as up, down, left, right, front, back, front, back, top, and bottom mentioned or possibly used in this specification are defined relative to the structures shown in the accompanying drawings. These are relative concepts and may therefore vary depending on their location and usage. Therefore, these or other directional terms should not be interpreted as restrictive. Furthermore, the terms "first," "second," "third," and similar expressions are used only for descriptive and distinguishing purposes and should not be construed as indicating or implying the relative importance of the corresponding components.

[0019] The following is in conjunction with the appendix Figure 1 - Appendix Figure 4 This application will be described in further detail.

[0020] This application discloses a novel swallowtail clip.

[0021] A novel dovetail clip includes a clip body 1 and two clip handles 2. The clip body 1 is formed by bending a piece of elastic metal material to form a ridge 11 and two symmetrically distributed clips 12. The ends of the clips 12 are curled outward to form a pivot shaft portion 3. The elastic metal material is prior art and will not be described in detail. The clip handles 2 are made of wound steel wire. Each clip handle 2 has a pivot post 21 at its end. The pivot shaft portion 3 has a first pivot groove 31, a buffer groove 33, and a second pivot groove 32 that are interconnected along the length of the clips 12. The pivot post 21 can be located in either the first pivot groove 31 or the second pivot groove 32, thereby fixing the clip handle 2 in different positions. The width of the buffer groove 33 is smaller than the diameter of the pivot post 21. Because the pivot shaft portion 3 has a certain degree of elasticity, the buffer groove 33 allows the pivot post 21 to pass through. The buffer groove 33 serves as a transition structure, providing resistance and positioning feel when switching the position of the clip handle 2, preventing the clip handle 2 from accidentally slipping out of the target groove, and improving the clarity and reliability of the operation.

[0022] The clip body 1 is also provided with a storage slot 13, which is used to accommodate the clip 2 when it is not in use (that is, when the clip 2 is not unfolded).

[0023] When the pivot post 21 is located in the first pivot groove 31, the handle 2 retracts inward, and part of the handle 2 enters the storage groove 13. At this time, the included angle between the two handles 2 becomes smaller, making the overall structure of the dovetail clip compact. When the pivot post 21 is located in the second pivot groove 32, part of the handle 2 emerges from the storage groove 13 and abuts against the outer surface of the clip 12. At this time, the handle 2 unfolds outward, and the user can press the two handles 2 to open the clip body 1, thus enabling the dovetail clip to clamp. The first pivot groove 31 is located further away from the central axis of the spine 11 than the second pivot groove 32. The position of the pivot post 21 can be switched by pulling or pushing the handle 2.

[0024] The storage slot 13 consists of two parts: a clearance area 131 located at the clip 12; and a storage area 132 extending into the spine 11. The function of the storage slot 13 is to prevent the clip body 1 from interfering with the rotation of the clip handle 2, allowing the handle 2 to continue rotating towards the clip body 1, thus achieving the effect that the total length of the dovetail clip is the length of the handle 2 minus the length of the clip body 1. When the handle 2 is in the stored state, it is located at the bottom of the storage area 132. At this time, the maximum distance between the outer sides of the two handles 2 is less than the overall width of the spine 11, making the clip appear flatter.

[0025] The two sidewalls of the storage area 132 gradually converge inwards towards the bottom from where they meet the clearance area 131, forming a guide slope to facilitate the smooth opening and closing of the handle 2. The minimum distance between the two sidewalls can also be set to be slightly smaller than the diameter of the handle 2, so that the storage area 132 can dampen the handle 2 through friction when the handle 2 is closed, thereby improving the stability of the dovetail clip when it is closed.

[0026] The bottom of the storage area 132 is an arc-shaped surface 1321, which is concentrically matched with the arc-shaped outer surface of the end of the handle 2, thereby improving the contact area and structural stability.

[0027] Detailed implementation: After clamping the document, push the handle to allow the pivot pin to move from the first pivot slot into the second pivot slot. At this time, part of the handle enters the storage slot, realizing the closing of the dovetail clip. This closed state of the dovetail clip does not affect the turning and reading of the document. On the other hand, multiple documents clamped by different dovetail clips can be stacked, and the user can also use the handle to quickly pick up documents from different positions.

[0028] The above are all preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, based on the technical solution of this utility model, those skilled in the art can propose various interchangeable structural methods and implementation methods without changing the essential spirit of this utility model. Therefore, the above specific embodiments and accompanying drawings are merely illustrative descriptions of the technical solution of this utility model and should not be considered as the entirety of this utility model or as a limitation or restriction on the technical solution of this utility model. Therefore, all equivalent changes made according to the structure, shape, and principle of this application should be covered within the scope of protection of this application.
