[0038] In this utility model, "first" and "second" do not represent a specific quantity or order, but are merely used to distinguish names.

[0039] On the one hand, such as Figure 1 and Figure 2 As shown, a paper cutter according to one embodiment of the present invention includes:

[0040] Mounting base 1 is provided with a rotating unit 11;

[0041] The connecting handle 2 is provided with a connecting part 21 that is rotatably connected to the rotating unit 11, a positioning end 22 disposed outside the mounting base 1, and a mounting end 23;

[0042] Tool holder 3 is disposed on the mounting end 23;

[0043] The cutting blade 4 is mounted on the tool holder 3;

[0044] A compression spring 5 is sleeved on the connecting handle 2, with one end pressing against the rotating unit 11 and the other end pressing against the tool holder 3.

[0045] The aforementioned paper cutter uses a compression spring 5 to press against the rotating unit 11 at one end and against the cutter holder 3 at the other end. When the cutting blade 4 is subjected to greater pressure during the cutting process, the compression spring 5 is compressed, and the cutter holder 3 can move relative to the rotating unit 11 along the axis of the connecting handle 2, thereby preventing the cutting blade 4 from breaking and improving its service life.

[0046] In one embodiment, the mounting base 1 includes a mounting cylinder 12 with a mounting opening and a cylinder cover 13 disposed on the mounting opening of the mounting cylinder 12; the outer wall of the mounting cylinder 12 is provided with a mounting groove; and the compression spring 5 is disposed inside the mounting cylinder 12. Thus, by disposing of the compression spring 5 inside the mounting cylinder 12, paper scraps can be prevented from entering the gaps in the compression spring 5 and affecting the performance.

[0047] In one embodiment, the rotating unit 11 includes a rotating sleeve 111 sleeved on the connecting handle 2, and a bearing assembly 112 connecting the rotating sleeve 111 and the mounting cylinder 12. Specifically, both the rotating sleeve 111 and the bearing assembly 112 are disposed within the mounting cylinder 12, and the rotating sleeve 111 is slidably connected to the connecting handle 2. Thus, by disposing of the bearing assembly 112 within the mounting cylinder 12, paper scraps can be prevented from entering the gaps in the bearing assembly 112 and affecting the performance.

[0048] In one embodiment, the tool holder 3 includes a tool holder body 31 connected to the connecting handle 2, and a fixing block 32 disposed on the tool holder body 31 via a limiting mounting structure 6. The tool holder body 31 has a mounting groove and a limiting flange disposed on the mounting groove. The cutting blade 4 has a blade back adapted to the mounting groove and a limiting arc adapted to the limiting flange. The fixing block 32 is used to press the blade back into the mounting groove. In this way, the blade back of the cutting blade 4 is installed into the mounting groove, the limiting arc matches the limiting flange, and the fixing block 32 presses the blade back into the mounting groove, ensuring that the installation of the cutting blade 4 is stable and reliable. At the same time, the cutting blade 4 is detachable, which facilitates the replacement of damaged blades.

[0049] In one embodiment, the limiting mounting structure 6 includes a threaded hole and a limiting protrusion 61 on the tool holder body 31, and a mounting hole and a limiting top surface 62 on the fixing block 32. Thus, the position of the fixing block 32 is defined by the contact between the limiting protrusion 61 and the limiting top surface 62, and the fixing block 32 is stably mounted on the tool holder body 31 by a screw passing through the mounting hole and locking it into the threaded hole.

[0050] In one embodiment, the blade holder body 31 includes a connector 311 connected to the connecting handle 2, and a blade holder body 312 connected to the connector 311 via a snap-fit ​​structure 33. The snap-fit ​​structure 33 includes a connecting groove 332 on the connector 311, a connecting flange 331 on the blade holder body 312, and fasteners for locking the connecting flange 331 and the connecting groove 332. Thus, by replacing the connector 311, different cutting blades 4 can be quickly replaced, thereby improving cutting efficiency.

[0051] In one embodiment, the cutting blade 4 has a cutting edge protruding from the cutter holder 3. This ensures that while the cutting edge of the cutting blade 4 cuts the paper, the contact area between the back of the cutting blade 4 and the cutter holder 3 is sufficiently large, thereby guaranteeing the best performance.

[0052] In one embodiment, the positioning end 22 is provided with a positioning groove arranged along the axial direction. Thus, by connecting the positioning groove to the hub of the rotating component, the rotation angle of the positioning groove is driven by the rotating component, thereby realizing the adjustment of the angle of the cutting blade 4.

[0053] On the other hand, such as Figure 3 As shown, a paper cutting device according to one embodiment of the present invention includes a paper cutting drive device 7 and a paper cutting blade 8; the paper cutting blade 8 is disposed on the paper cutting drive device 7.

[0054] In one embodiment, the paper-cutting drive device 7 includes a paper-cutting platform 71, a first drive component 72, a second drive component 73, a third drive component 74, and a paper-cutting support 75. The paper-cutting blade 8 is mounted on the paper-cutting support 75. The first drive component 72 drives the paper-cutting support 75 to move relative to the paper-cutting platform 71 along a first direction. The second drive component 73 drives the paper-cutting support 75 to move relative to the paper-cutting platform 71 along a second direction. The third drive component 74 drives the paper-cutting platform 71 to move relative to the paper-cutting support 75 along a third direction. Specifically, the first direction, the second direction, and the third direction are perpendicular to each other, corresponding to the X, Y, and Z axes, respectively. This allows the paper-cutting support 75 to move relative to the paper-cutting platform 71 along the X, Y, and Z axes.

[0055] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0056] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
