Description

[Technical field]

[0001] The utility model relates to the technical field of hollow dovetail clips, in particular to a hollow dovetail clip. [Background technology]

[0002] The hollow dovetail clip is a type of dovetail clip, which is mainly used to collect a stack of documents. It is a commonly used office stationery. It has a relatively simple structure, is cheap, and is easy and convenient to operate. Therefore, it has been widely used. The existing dovetail clip is mainly composed of a hollow clip body and a tail handle. The document is clamped by the hollow clip body, and then the tail handle connected to the hollow clip body is rotatably attached to the document to fix the document. The setting of the hollow clip body can mainly prevent the text from being blocked by the dovetail clip, thereby preventing the copy from being blocked;

[0003] Although the above scheme can fix the file, the following problems still exist: first, the thickness of the file will change according to the amount of documents, and the opening and closing angle of the hollow dovetail clip in the above scheme is fixed. When there are fewer files, the files will be clamped and fixed by the hollow dovetail clip, but when there are more files, since the opening and closing size of the hollow clamp body in the above scheme is fixed, when the opening and closing size is smaller than the thickness of the file, the hollow dovetail clip needs to be replaced to a size corresponding to the thickness of the file in order to clamp the file, which makes the dovetail clip unable to clamp files of various thicknesses, resulting in poor applicability. [Contents of the utility model]

[0004] The purpose of the utility model is to solve the problems in the prior art and to provide a hollow dovetail clip that can clamp documents.

[0005] To achieve the above-mentioned purpose, the utility model proposes a hollow dovetail clamp, comprising: a hollow clamp body and a tail handle rotatably connected to the hollow clamp body.

[0006] Also includes:

[0007] Two support seats, the two support seats are fixedly connected to the side walls on both sides of the hollow clamp body;

[0008] A moving block corresponding to the supporting seat, wherein the moving block is slidably connected to the supporting seat;

[0009] A rotating column, the rotating column is rotatably connected to the moving block, and both ends of the rotating column extend outside the supporting seat, and the rotating column is slidably connected to the supporting seat;

[0010] Two connecting blocks and clamping plates corresponding to the connecting blocks, the two connecting blocks are elastically slidably connected to the rotating columns respectively, and the clamping plates are fixedly connected to the connecting blocks respectively.

[0011] Preferably, a positioning block is fixedly connected to one of the clamping plates, and a positioning groove for the positioning block to enter is formed on the other clamping plate.

[0012] Preferably, the positioning block is elastically slidably connected to a fixing block, the fixing block is rotatably connected to a ball 1, and the positioning groove is provided with a fixing groove for the ball 1 to enter.

[0013] Preferably, a spring 1 is fixedly connected to the positioning block, and one end of the spring 1 is fixedly connected to the fixing block.

[0014] Preferably, a limit baffle is fixedly connected to the rotating column, and a side wall of the limit baffle is in contact with a side wall of the moving block.

[0015] Preferably, a second ball is rotatably connected to the rotating column, and the second ball is in contact with the moving block.

[0016] The beneficial effects of the utility model are as follows: compared with the prior art, the utility model adjusts the position of the clamping plate indirectly by moving the moving block arranged on the support seat. Once the position adjustment of the clamping plate is completed, the personnel can put the document into the clamping plate. By resetting the clamping plate, the document can be clamped. By putting the document into the clamping plate for clamping, it is possible to clamp documents of various thicknesses, thereby increasing the applicability of the dovetail clamp. By clamping at the edge of the document, the clamp body is set in a hollow shape, which is convenient for personnel to view the contents of the document without worrying about the document being blocked by the clamp body.

[0027] like Figures 1 to 4 , a hollow dovetail clamp, comprising: a hollow clamp body 1 and a tail handle 2 rotatably connected to the hollow clamp body 1, the hollow clamp body 1 is hollow;

[0028] The dovetail clamp of the utility model further includes: two support seats 3, a moving block 4 corresponding to the support seats 3, a rotating column 5, two connecting blocks 6 and a clamping plate 7 corresponding to the connecting blocks 6.

[0029] Two of the support seats 3 are fixedly connected to the side walls on both sides of the hollow clamping body 1, and the moving blocks 4 are slidably connected to the support seats 3 respectively. When the document needs to be clamped, the personnel can slide the moving block 4. When the moving block 4 slides to the required position, the rotating column 5 is rotated. The rotation of the rotating column 5 drives the connecting block 6 to drive the clamping plate 7 to adjust the position. Once the position adjustment of the clamping plate 7 is completed, the personnel pulls the connecting block 6 elastically slidably connected to the rotating column 5, so that the connecting block 6 drives the clamping plate 7 fixedly connected to it to adjust the position so that the document is located in the clamping plate 7. At this time, the personnel releases the clamping plate 7 and resets the connecting block 6 to fix the document. It is worth mentioning that the connecting block 6 is elastically connected by the spring 2 16, and the spring 2 16 is fixedly connected to the rotating column 5, and one end is fixedly connected to the connecting block 6, so that the resetting of the connecting block 6 can be achieved.

[0030] Specifically, a positioning block 8 is fixedly connected to one of the clamping plates 7 , and a positioning groove 9 for the positioning block 8 to enter is opened on the other clamping plate 7 . The positioning block 8 enters the positioning groove 9 , thereby achieving the positioning of the two clamping plates 7 .

[0031] Specifically, the fixing block 10 is elastically slidably connected to the positioning block 8, and the ball 11 connected to the fixing block 10 is rotated to enter the fixing groove 12 provided on the positioning groove 9, thereby achieving the fixing of the positioning block 8.

[0032] Specifically, a spring 13 is fixedly connected to the positioning block 8, and one end of the spring 13 is fixedly connected to the fixing block 10, so that the fixing block 10 can be reset.

[0033] Specifically, since the limiting baffle 14 is fixedly connected to the rotating column 5, the side wall of the limiting baffle 14 is in contact with the side wall of the moving block 4. Therefore, the limiting baffle 14 is in contact with the moving block 4, and thus the rotating column 5 can be limited to prevent the rotating column 5 from moving outside the moving block 4.

[0034] Specifically, the second ball 15 is rotatably connected to the rotating column 5 , and the second ball 15 is in contact with the moving block 4 , thereby reducing the friction between the moving block 4 and the rotating column 5 .

[0035] The principle of the utility model is as follows: by moving the moving block 4, the clamping plate 7 is adjusted to the required position, and the clamping plate 7 is pulled to open the two clamping plates 7 outwards. At this time, the document is placed between the clamping plates 7. When the document is placed between the clamping plates 7, the clamping plates 7 are released, and the clamping of the document can be achieved by the relative resetting of the clamping plates 7.

[0036] The above embodiments are intended to illustrate the present invention, not to limit the present invention. Any solution that is a simple transformation of the present invention falls within the protection scope of the present invention.
