[0012] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0013] like Figures 1 to 3As shown, a sandpaper cutting device includes: a first body 2, a second body 3, a handle 4, and a cutting wheel 5. The first body 2 has a first connecting part 21 and a mounting part 22. The second body 3 is cross-connected to the first body 2 by a pin 6. The second body 3 has a second connecting part 31 and a supporting bottom 32. The mounting part 22 corresponds to the supporting bottom 32, and a cutting hole 321 is provided on the supporting bottom 32. The first connecting part 21 corresponds to the second connecting part 31, and an adjustment component 7 is provided between the first connecting part 21 and the second connecting part 31. The adjustment component 7 is used to adjust the distance between the mounting part 22 and the supporting bottom 32. The handle 4 is connected to the second connecting part 31. The cutting wheel 5 is rotatably mounted on the mounting part 22, and the cutting wheel 5 can partially extend into the cutting hole 321.

[0014] The sandpaper cutting device is adjustable through a cross-connection structure between the first main body 2 and the second main body 3, similar to scissors, but without the need for repeated hand gripping. During operation, the operator holds the handle 4 connected to the second connecting part 31 and directly pushes the cutting device to move horizontally, causing the cutting wheel 5 on the mounting part 22 and the support bottom 32 to generate relative movement with the sandpaper 100. Since the cutting wheel 5 can partially extend into the cutting hole 321 of the support bottom 32, when the sandpaper 100 is placed between the mounting part 22 and the support bottom 32, the cutting wheel 5 will cut the sandpaper while rotating. At the same time, the adjustment component 7 between the first connecting part 21 and the second connecting part 31 can flexibly adjust the distance between the mounting part 22 and the support bottom 32 to adapt to sandpaper of different thicknesses, ensuring a stable and efficient cutting process, and making the cutting process easy and convenient.

[0015] Compared to ordinary scissors, it reduces the direct force exerted by the worker's hands, effectively alleviating discomfort during cutting. Cutting can be achieved by simply pushing the cutting device. With the help of the adjustment component 7 to adjust the distance between the mounting part 22 and the support bottom 32, it can meet the cutting needs of sandpaper of different specifications and thicknesses, improving the versatility of the device and eliminating the need for frequent tool changes.

[0016] Specifically, the adjusting assembly 7 includes a connecting cylinder 71, a bolt 72, and a torsion spring 73. A through hole is provided on the second connecting part 31. The two ends of the torsion spring 73 are respectively connected between the first connecting part 21 and the second connecting part 31 so that the first connecting part 21 and the second connecting part 31 are far apart from each other. The connecting cylinder 71 is fixed on the first connecting part 21. The bolt 72 passes through the through hole and is threadedly connected to the connecting cylinder 71. Tightening the bolt 72 can bring the first connecting part 21 and the second connecting part 31 closer together, while the mounting part 22 and the support bottom 32 are close to each other.

[0017] The adjusting component 7 adjusts the distance between the mounting part 22 and the support bottom 32 through the coordinated action of the connecting cylinder 71, bolt 72, and torsion spring 73. The two ends of the torsion spring 73 are connected to the first connecting part 21 and the second connecting part 31 respectively. Its own elastic force will cause the first connecting part 21 and the second connecting part 31 to move away from each other, thereby driving the mounting part 22 and the support bottom 32 closer together. When it is necessary to reduce the distance between the two, the operator can tighten the bolt 72, which passes through the through hole of the second connecting part 31 and is threaded to the connecting cylinder 71 on the first connecting part 21. As the bolt 72 is tightened, it will push the second connecting part 31 closer to the first connecting part 21, overcoming the elastic force of the torsion spring 73, so that the mounting part 22 and the support bottom 32 move closer together, thereby achieving the purpose of adjusting the distance. When the bolt 72 is loosened, the elastic force of the torsion spring 73 will play a role again, allowing the first connecting part 21 and the second connecting part 31 to return to a state of moving away from each other, and the mounting part 22 and the support bottom 32 will move closer together.

[0018] The threaded connection between bolt 72 and connecting sleeve 71 has precise adjustment characteristics. By controlling the tightening degree of bolt 72, the operator can precisely control the distance between the mounting part 22 and the support bottom 32 to meet the cutting needs of sandpaper of different thicknesses. At the same time, the self-locking property of the threaded connection can ensure the stability of the adjusted distance and prevent it from changing due to force during the cutting process, thus ensuring the stability of the cutting work.

[0019] Bolt 72 can move back and forth in the through hole during adjustment. The cap end 721 of bolt 72 abuts against the second connecting part 31, and the threaded part 722 of bolt 72 is threadedly connected to the connecting cylinder 71.

[0020] Specifically, the two ends of the torsion spring 73 are welded to the first connecting part 21 and the second connecting part 31, respectively.

[0021] It can effectively prevent problems such as loosening and falling off during long-term and frequent stress expansion and contraction and device operation, ensuring that the torsion spring 73 can always stably perform its elastic restoring function.

[0022] Specifically, handle 4 is made of rubber.

[0023] Specifically, the first body 2 and the second body 3 are made of steel.

[0024] Specifically, the handle 4 is arranged parallel to the support bottom 32.

[0025] The parallel design ensures that when the operator grips the handle 4, the direction of force applied by their hand is consistent with the force-bearing surface of the support base 32, conforming to natural force application habits. In practical applications, the height of the sandpaper 100 production line is relatively high, making this design more comfortable to use.

[0026] It should be noted that all directional indications in the embodiments of the present invention, such as up, down, left, right, front, back, etc., are only used to explain the relative positional relationship and movement of the components in a specific posture, as shown in the attached figure. If the specific posture changes, the directional indication will also change accordingly.

[0027] Furthermore, the use of terms such as "first" and "second" in this invention is for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features. Meanwhile, the word "and / or" throughout the text means including three solutions; for example, "A and / or B" includes solution A, solution B, or a solution that simultaneously satisfies A and B. Additionally, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed by this invention.
