Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of accounting file processing equipment, specifically to a document cutting device for accounting files. Background Technology
[0002] In the daily management and organization of accounting records, it is often necessary to trim the edges of documents or cut the paper to meet the requirements of classification, binding, or filing. Therefore, specialized document trimming devices are usually provided to help staff complete the trimming tasks efficiently.
[0003] Most existing document cutting devices use an exposed blade structure, meaning the blade is often exposed when not in use, making it susceptible to scratches or damage from accidental contact. Therefore, some devices have added protective plates to the blade area, but these protective structures are mostly manually operated, making them cumbersome to use. Utility Model Content
[0004] To address the shortcomings of existing technologies, this utility model provides a document trimming device for accounting archives.
[0005] To achieve the above objectives, the technical solution of this utility model is as follows:
[0006] An accounting document trimming device, comprising:
[0007] Placement board;
[0008] The cutter is rotatably mounted on one side of the aforementioned placement plate, and a protective plate is rotatably mounted on the side wall away from the placement plate to protect it. The protective plate has a mating block on the side near the free end of the cutter.
[0009] The handle is fixed to the free end of the cutter and is surrounded by an air bladder. A sealed gap is formed between the air bladder and the handle. A telescopic rod is slidably provided on the handle. One end of the telescopic rod is located between the cutter and the air bladder, and the other end extends to the side of the handle facing the guard plate. A pressing block that acts on the mating block is fixed at this end.
[0010] When the gap between the handle and the airbag is compressed, the telescopic rod and the compression block are pushed out toward the mating block, and the compression block compresses the guard plate to rotate through the mating block.
[0011] Preferably, the telescopic rod and the compression block can move 3mm-10mm toward the mating block.
[0012] Preferably, the guard plate can rotate 30°-90° relative to the cutter. When the guard plate is rotated to its maximum range, it is completely located on the side of the cutter away from the placement plate.
[0013] Preferably, when the cutter cuts the document, the telescopic rod and the extrusion block always tend to move toward the mating block.
[0014] Preferably, the aforementioned guard plate is initially attached to the bottom wall of the cutter.
[0015] Preferably, the bottom wall of the cutter has an arc-shaped structure, and the cutter can rotate up to a right angle with the placement plate.
[0016] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0017] 1. By utilizing the natural squeezing action of the airbag when holding the handle, the telescopic rod and squeezing block are driven to automatically push the guard plate to rotate and open. No additional steps are required in the operation process, realizing the automatic release of the protective structure before cutting, which improves the human-machine interaction and work efficiency.
[0018] 2. By setting a rotatable guard plate on the cutter and designing an automatic opening structure controlled by the handle and airbag, the blade edge can be automatically covered when not in use, avoiding the risk of accidental injury caused by the exposed cutter, and significantly improving the safety of the document cutting device during use and storage.

[0028] It is readily understood that, based on the technical solution of this utility model, those skilled in the art can propose various interchangeable structural methods and implementations without altering the essential spirit of this utility model. Therefore, the following detailed 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 limitations or restrictions on the technical solution of this utility model.
[0029] Example
[0030] like Figures 1-4 As shown, a document cutting device for accounting archives includes a placement plate 1, a cutter 2, a guard plate 21, a handle 3, an airbag 31, a telescopic rod 32, and a pressing block 321. The placement plate 1 is used to support the documents to be cut and has good stability and load-bearing capacity. The cutter 2 is rotatably mounted on one side of the placement plate 1 and is used to cut the documents. Its cutting path is set along the edge or top of the placement plate 1, which can accurately trim the edges of the documents.
[0031] In one embodiment, such as Figures 2-3 As shown, to improve safety during use, a protective plate 21 is rotatably mounted on the side wall of the cutter 2 away from the placement plate 1. This protective plate 21 is usually in its initial position covering the bottom of the cutter 2, used to shield the cutting edge and effectively prevent the user from coming into contact with the sharp blade and causing injury when not cutting. A mating block 211 is located on the side of the protective plate 21 near the free end of the cutter 2. This mating block 211 provides a force-bearing point for the protective plate 21. Through its cooperation with the pressing block 321, the protective plate 21 can be rotated open before the cutting operation.
[0032] In one embodiment, such as Figures 2-3 As shown, the handle 3 is fixed to the free end of the cutter 2, used for manual gripping and controlling the rotation of the cutter 2 to achieve the cutting action. An airbag 31 surrounds the handle 3, forming a sealed gap between the airbag 31 and the handle 3. When the user grips the handle 3 tightly, the airbag 31 is compressed, and the gap is closed. A telescopic rod 32 is slidably mounted on the handle 3. One end of the telescopic rod 32 is located between the cutter 2 and the airbag 31, and the other end extends to the side of the handle 3 facing the guard plate 21, with a pressing block 321 fixed to this end, acting on the mating block 211. When the gap between the handle 3 and the airbag 31 is compressed, the telescopic rod 32 and the pressing block 321 push out towards the mating block 211, and the pressing block 321 compresses the guard plate 21 to rotate via the mating block 211. This automatically triggers the opening action of the guard plate 21, improving operational convenience and safety, eliminating the need for manual opening of the protective components, and enhancing the ergonomics of the equipment.
[0033] In one embodiment, such as Figures 2-3As shown, the telescopic rod 32 and the compression block 321 can move 3mm-10mm toward the mating block 211. This distance range ensures that the displacement generated when the airbag 31 is compressed is sufficient to trigger the rotation of the guard plate 21, while avoiding mechanical interference or structural fatigue due to excessive displacement, thus ensuring the long-term stable operation of the entire device. By limiting the amount of telescopic displacement, the control accuracy and response consistency of the device are enhanced.
[0034] In one embodiment, such as Figures 2-3 As shown, the guard plate 21 can rotate 30°-90° relative to the cutter 2. At the maximum rotation angle, the guard plate 21 is completely located on the side of the cutter 2 away from the placement plate 1, meaning the guard plate 21 is flipped up to an area that does not interfere with the cutting action of the cutter 2, allowing the cutter 2 to execute the cutting path completely. This structure avoids the guard plate 21 obstructing the cutting area when open, improving cutting efficiency and operational smoothness. When the guard plate 21 is rotated to its maximum extent, it is completely located on the side of the cutter 2 away from the placement plate 1, allowing the guard plate 21 to fit completely against the back of the cutter 2, further saving space and avoiding interference during the cutter's movement.
[0035] In one embodiment, such as Figures 2-3 As shown, when the cutter 2 is cutting the document, the telescopic rod 32 and the pressing block 321 always tend to move towards the mating block 211, that is, they are always in a state of accumulating pressure. This setting can be achieved by setting an elastic reset structure or adjusting the internal pressure of the airbag 31, so that the guard plate 21 remains open during cutting and will not return to its original position when the hand is not holding it steadily, thereby improving the reliability and operational safety of the device.
[0036] In one embodiment, such as Figures 2-3 As shown, the guard plate 21 initially adheres to the bottom wall of the cutter 2, covering the exposed blade edge and forming a complete safety protection surface. When not in use, the guard plate 21 remains attached to the bottom of the cutter 2, preventing the cutter 2 from being directly exposed and reducing the risk of scratches during storage, handling, and accidental contact. This structure makes the device more compliant with safety requirements in office environments.
[0037] In one embodiment, such as Figures 2-3 As shown, the bottom wall of the cutter 2 has an arc-shaped structure. The cutter 2 can rotate to a right angle with the placement plate 1. This structure facilitates the achievement of maximum cutting depth and improves the adaptability of the device to various paper thicknesses. The arc-shaped bottom wall, combined with the right-angle opening and closing path, effectively improves the cutting feel and cutting accuracy.
[0038] By combining the opening control of the guard plate 21 with the compression structure of the airbag 31 on the handle 3, the guard plate 21 is "passively opened," which does not affect operation and improves safety. The overall structure is cleverly integrated into the conventional operation path, with a novel concept and obvious creativity.
[0039] The technical scope of this utility model is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the protection scope of this utility model.
