Description

Technical Field

[0001] The utility model relates to the technical field of clip, in particular to a new type of clip. Background Art

[0002] The clip is also known as the long-tail clip, a kind of stationery clip made of metal, used to gather a stack of documents together, also known as the phoenix tail clip and ticket clip. The handle is movable, the paper clamping is tight and not easy to fall off; made of pure metal material, it is convenient to disassemble, recyclable, environmentally friendly and durable.

[0003] The traditional clip consists of a spring plate clip body and two relatively long tail handles. The clip body is a spring steel sheet formed in one piece, while the tail handle is generally made of steel wire, and one end connected to the clip body is movable. This design enables the steel wire clip to be laid flat after clamping the documents, facilitating the stacking of documents and saving space.

[0004] However, the length of the tail handle of the clip is fixed, and it is inconvenient to adjust the length of the tail handle of the clip according to needs during use, and it is inconvenient for personnel to press and save effort. Content of the Utility Model

[0005] The purpose of the utility model is to provide a new type of clip that can facilitate personnel to adjust the length of the tail handle.

[0006] The above technical purpose of the utility model is achieved through the following technical solutions: a new type of clip, including a clip body and a connecting handle rotatably connected to one end thereof. There are two groups of the connecting handles, which are oppositely arranged at both ends of the clip body. An extension handle is rotatably arranged at one end of the connecting handle away from the clip body. A connecting block is slidably arranged at the connection between the extension handle and the connecting handle. A receiving groove is formed on the connecting block, and the connection between the extension handle and the connecting handle is located in the receiving groove.

[0007] Preferably, the extension handle is connected to the connecting handle through a connecting disk, a sliding groove is formed in the receiving groove, and the connecting disk is slidably connected to the sliding groove.

[0008] Preferably, there are two groups of the connecting blocks, which are oppositely arranged at one end of the connecting handle away from the clip body, and a limiting rod is respectively inserted through one end of the two groups of the connecting blocks close to each other.

[0009] Preferably, a slot and a plug rod that are inserted and matched with each other are oppositely arranged on the relatively close sides of the two groups of connecting blocks respectively.

[0010] Preferably, a friction pad is arranged on the outer wall of the plug rod.

[0011] Preferably, a dial block is arranged at one end of the extension handle away from the connection with the connecting handle.

[0012] Advantages of the present utility model: By rotatably arranging an extension handle on the connection handle and slidably arranging a connection block at the connection between the extension handle and the connection handle, the connection between the extension handle and the connection handle is limited by the connection block. Personnel can open the dovetail frame body by pressing the extension handle, reducing the pressing force required by the personnel. Compared with the prior art, the present utility model enables personnel to conveniently adjust the length of the tail handle, providing more choices for the personnel to select the pressing position. The connection block on the connection handle increases the contact surface when the personnel press, and it is more comfortable for the personnel to press the connection handle through the connection block.

[0018] The following is only the preferred embodiment of the present utility model, and the protection scope is not limited to this embodiment. Any technical solution falling within the idea of the present utility model shall belong to the protection scope of the present utility model. At the same time, it should be noted that for those of ordinary skill in the art in this technical field, several improvements and refinements made without departing from the principle of the present utility model should also be regarded as the protection scope of the present utility model.

[0019] It should be noted that in this article, relational terms such as first and second, such as "connection plate one, connection plate two", are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations.

[0020] The orientation terms mentioned in this embodiment, such as "up, down, left, right", etc., are only used to assist those skilled in the art in this technical field to understand the connection between each feature or part through each drawing.

[0021] In this embodiment, unless otherwise clearly specified and defined, terms such as "connection" and "fixation" shall be understood in a broad sense. For example, "fixation" can be a fixed connection, a detachable connection, or an integral one; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two components or the interaction relationship between two components. Unless otherwise clearly defined, for those of ordinary skill in the art, the specific meanings of the above terms in this utility model can be understood according to specific circumstances.

[0022] As Figures 1 to 4 shown, a new type of clip includes a clip body 1 and a connecting handle 2 rotatably connected to one end thereof. There are two groups of connecting handles 2, and the two groups of connecting handles 2 are oppositely arranged at both ends of the clip body 1. The end of the connecting handle 2 far from the clip body 1 is connected to an extension handle 3 through a connecting disc 4. In this embodiment, the end of the connecting handle 2 far from the clip body 1 is in a disconnected state, forming two breakpoints. Connecting discs 4 are arranged on both breakpoints. The two ends of the extension handle 3 are respectively connected to the two groups of connecting discs 4, and a rectangular connecting block 5 is slidably arranged at the connection between the connecting handle 2 and the extension handle 3. A receiving groove 6 is opened in the middle of the connecting block 5, and a sliding groove 7 is opened on the inner wall of the receiving groove 6. The connecting disc 4 is slidably connected to the sliding groove 7. Shafts 8 in the shape of a capital I are respectively inserted through the ends of the two groups of connecting blocks 5 close to each other, and the position of the shafts 8 is between the connecting handle 2 and the extension handle 3. The purpose is to ensure that the connecting block 5 does not slide out of the connecting handle 2 during the sliding process of the connecting block 5 through the shafts 8, playing a limiting role on the connecting block 5.

[0023] Slots 9 and inserting rods 11 in plug-in fit are oppositely arranged on the sides of the two groups of connecting blocks 5 close to each other, and a friction pad 10 is arranged on the outer wall of the inserting rod 11. The purpose is to increase the friction between the inserting rod 11 and the slot 9. A dial block 12 is arranged at the end of the extension handle 3 far from its connection with the connecting handle 2. The purpose is to facilitate personnel to drive the extension handle 3.

[0024] When personnel do not extend and use the clip, as Figure 1 shown, the extension handle 3 is located inside the connecting handle 2, and the two groups of opposite connecting blocks 5 are not plugged in. Personnel can press the connecting block 5 to use the clip.

[0025] When personnel need to adjust the pressing position, they can start to rotate the extension handle 3 through the dial block 12. As Figure 2 shown, the extension handle 3 is rotated around the central axis of its connection with the connecting handle 2 until it is appropriate. Then personnel start to push the two groups of connecting blocks 5 closer, so that the inserting rod 11 is inserted into the slot 9 to limit the sliding of the connecting block 5. Then personnel can press the extension handle 3, and it will be more labor-saving to open and close the clip body 1.

[0026] The above embodiments are illustrative of the present utility model and not restrictive thereof. Any solution obtained by a simple transformation of the present utility model falls within the protection scope of the present utility model.
