[0002] The office stationery product category is developing rapidly. The demand for paper cutters has increased significantly in offices, schools, and homes, and most customers are also demanding higher cost-performance ratios from paper cutters.

[0003] Existing paper cutters generate paper scraps when cutting paper. In addition, the lack of an integrated structure to clean up the paper scraps causes them to accumulate inside the cutting groove, which affects the subsequent cutting quality. To address this, we provide a paper cutter with adjustable blades. Utility Model Content

[0004] To address the problem in the aforementioned background technology where paper scraps are difficult to remove during paper cutting, causing them to accumulate in the cutting groove and affecting the subsequent paper cutting quality, this utility model provides a paper cutter with easily adjustable blades.

[0005] This utility model is achieved by the following technical solution: a paper cutter with easy-to-adjust blades, including a chassis and a cleaning component, a crossbeam is provided above the chassis, a cutting component is movably mounted on the crossbeam, and a cutting groove is provided on the top of the chassis.

[0006] The cleaning component includes two sets of movable slots symmetrically arranged on the chassis. A limiting plate is movably connected inside the movable slot. A spring is also added inside the movable slot. A vertical rod is fixedly connected to the top of the limiting plate, and the top end of the vertical rod extends to the outside of the movable slot and is fixedly connected to the crossbeam. A strip groove is fixedly connected between the movable slot and the cutting slot. A push block is movably connected inside the cutting slot. A strip connecting frame is movably connected inside the strip groove, and both ends of the strip connecting frame are fixedly connected to the limiting plate and the push block, respectively.

[0007] As a further improvement to the above solution, the cutting assembly includes a side shell 1, a connecting plate fixedly connected to the side shell 1 by screws, a connecting seat rotatably connected to the connecting plate, three sets of cutting blades provided on the connecting seat, a connecting cover fixedly connected to the connecting seat, a side shell 2 fixedly connected to one side of the side shell 1 by screws, the bottom of the side shell 1 and the side shell 2 are snap-fitted to the same bottom shell and the bottom shell is slidably connected to the crossbeam, and a knob is provided on the outer side of the side shell 1 and the knob is fixedly connected to the connecting seat.

[0011] As a further improvement to the above solution, EVA anti-slip pads are fixedly connected to the four corners of the bottom of the chassis.

[0012] As a further improvement to the above solution, the surface of the knob is provided with three sets of pattern markings with different cutting methods.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] 1. This utility model uses downward pressing of the crossbeam and the movable cooperation between the limiting plate and the movable groove to drive the pressure bar to press down on the paper and drive the cutting blade to move closer to the paper. At this time, the spring is compressed, and when the limiting plate moves down, it also drives the pushing block fixedly connected to it via the strip connecting frame to move down together. At this time, the cutting groove is exposed to facilitate the cutting of the paper. When the crossbeam is released after cutting, the elasticity of the spring itself causes the crossbeam to automatically return to its original position. At this time, the pushing block also returns to its original position to push out the paper scraps that have fallen into the cutting groove, thereby achieving the purpose of automatic cleaning. This effectively avoids the problem that paper scraps generated during paper cutting are difficult to remove, causing them to accumulate in the cutting groove and affecting the subsequent cutting quality of the paper.

[0015] 2. This utility model allows for free switching between three sets of cutting blades by rotating a knob to achieve straight cutting, point cutting, and wave cutting, thereby increasing the practicality of the device. Attached Figure Description

Detailed Implementation

[0021] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments. Example

[0022] Please combine Figure 1-3 This embodiment of a paper cutter with an adjustable blade includes a chassis 1, a crossbeam 2 above the chassis 1, a cutting assembly 3 movably mounted on the crossbeam 2, and a cutting groove 4 on the top of the chassis 1.

[0023] A cleaning assembly for cleaning paper scraps inside the cutting groove 4 includes two sets of movable grooves 101 symmetrically arranged on the chassis 1. A limiting plate 102 is movably connected inside each movable groove 101. A spring 103 is also installed inside each movable groove 101, with both ends of the spring 103 fixedly connected to the bottom of the inner cavity of the movable groove 101 and the limiting plate 102, respectively. A vertical rod 104 is fixedly connected to the top of the limiting plate 102, and the top end of the vertical rod 104 extends to the outside of the movable groove 101 and is fixedly connected to the crossbeam 2. Next, a strip groove is fixedly connected between the movable groove 101 and the cutting groove 4. A push block 105 is movably connected inside the cutting groove 4. A strip connecting frame 106 is movably connected inside the strip groove, and both ends of the strip connecting frame 106 are fixedly connected to the limiting plate 102 and the push block 105, respectively. The cross-sectional size of the push block 105 matches the cross-sectional size of the cutting groove 4, so as to completely push the paper scraps out of the cutting groove 4. Pressure strips 5 are fixedly connected to the lower parts of both sides of the crossbeam 2, so as to press down the paper.

[0024] The cutting assembly 3 includes a side housing 301, a connecting plate 302 fixedly connected to the side housing 301 by screws, a connecting seat 303 rotatably connected to the connecting plate 302, three sets of cutting blades 304 provided on the connecting seat 303, and a connecting cover 305 fixedly connected to the connecting seat 303. A side housing 306 is fixedly connected to one side of the side housing 301 by screws. The bottom of the side housing 301 and the side housing 306 are snapped together with the same bottom housing 307, and the bottom housing 307 is slidably connected to the crossbeam 2. A knob 308 is provided on the outside of the side housing 301 and is fixedly connected to the connecting seat 303. The surface of the knob 308 is provided with three sets of pattern markings for different cutting methods, making it easy to switch cutting methods clearly and easily.

[0025] The implementation principle of a paper cutter with an adjustable blade in this embodiment is as follows: First, the paper is placed on the base plate 1 and passes under the crossbeam 2. Then, the crossbeam 2 is pressed down, and the movable cooperation between the limiting plate 102 and the movable groove 101 is used to drive the pressure bar 5 to press down on the paper and drive the cutting blade 304 to move closer to the paper. At this time, the spring 103 is compressed, and when the limiting plate 102 moves down, it also drives the push block 105, which is fixedly connected to it through the strip connecting frame 106, to move down together. At this time, the cutting groove 4 is exposed to facilitate cutting the paper. Then, the cutting assembly 3 is pulled to slide on the crossbeam 2, so that the cutting blade... The blade 304 cuts the paper, then releases the crossbeam 2. Utilizing the elasticity of the spring 103, the crossbeam 2 automatically resets. At this time, the push block 105 also resets to push out the paper scraps that have fallen into the cutting groove 4, thus achieving automatic cleaning. This effectively avoids the problem of paper scraps accumulating in the cutting groove and affecting the subsequent paper cutting quality due to the difficulty in removing paper scraps generated during paper cutting. Finally, the cut paper can be removed. By rotating the knob 308, the three sets of cutting blades 304 can be freely switched to achieve straight cutting, point cutting, and wave cutting, thereby increasing the practicality of the device. Example

[0026] Based on Example 1, this embodiment is further improved in that: EVA anti-slip pads are fixedly connected to the four corners of the bottom of the chassis 1, which can play an anti-slip role and ensure the stability when cutting paper.
