[0003] Therefore, it is necessary to provide a cutting device to solve the above problems. Utility Model Content

[0004] In order to solve the above technical problems, the utility model provides the following technical solutions:

[0005] A cutting device comprises a support assembly and a circular wheel cutter. A height-adjustable connecting shaft is provided at the lower end of the support assembly. The circular wheel cutter is rotatably connected to the outside of the connecting shaft. Two auxiliary wheels with symmetrical structures are also installed at the lower end of the support assembly.

[0006] Preferably, the bracket assembly includes an upper circular plate, and two structurally symmetrical brackets are installed at the lower end of the upper circular plate. A thickened platform is provided at the lower end of the bracket, and a long hole is opened on the thickened platform. The connecting shaft passes through the two long holes and a No. 1 nut is provided at its outer end for fastening.

[0007] Preferably, screws are provided at both ends of the connecting shaft, and the screws pass longitudinally through the long hole and the thickened platform and are fastened by a No. 2 nut.

[0008] Preferably, a size mark is provided on the side of the bracket, and the size mark is located above the thickened platform.

[0009] Preferably, a handle is provided at the upper end of the upper circular plate.

[0010] The beneficial effects of the utility model are as follows: the device has a simple structure, low manufacturing cost and a wide range of applications. The relative height difference between the circular wheel cutter and the auxiliary wheel can be adjusted by setting a screw to adjust the position of the connecting shaft on the long hole. It is suitable for cutting at different depths, and the auxiliary wheels on both sides of the circular wheel cutter play a supporting role, making the entire device more stable during operation and the cutting route easier to control than an ordinary knife.

[0015] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0016] like Figures 1 to 3 As shown, a cutting device includes a bracket assembly 1 and a circular wheel cutter 2. The lower end of the bracket assembly 1 is provided with a connecting shaft 3 with adjustable height. The circular wheel cutter 2 is rotatably connected to the connecting shaft 3. The lower end of the bracket assembly 1 is also equipped with two auxiliary wheels 12 with symmetrical structures. Specifically, the auxiliary wheels 12 are installed at the lower end of the bracket 5.

[0017] In this embodiment, the bracket assembly 1 includes an upper circular plate 4, and two symmetrical brackets 5 are installed at the lower end of the upper circular plate 4. A thickened platform 6 is provided at the lower end of the bracket 5, and a long hole 7 is opened on the thickened platform 6. The connecting shaft 3 passes through the two long holes 7 and a No. 1 nut 8 is fastened at its outer end.

[0018] In this embodiment, screws 9 are provided at both ends of the connecting shaft 3 , and the screws 9 longitudinally pass through the long hole 7 and the thickened platform 6 and are fastened by a No. 2 nut 10 .

[0019] In this embodiment, the side of the bracket 5 is provided with a size mark, and the size mark is located above the thickened platform 6. It is convenient to know the actual height size of the connecting shaft 3 with the circular wheel cutter 2 adjusted.

[0020] In this embodiment, a handle 11 is provided at the upper end of the upper circular plate 4 to facilitate the user to hold and cut.

[0021] Working process and principle:

[0022] According to the use requirements, the position of the connecting shaft 3 on the long hole 7 is adjusted by the screw 9 and locked with the No. 2 nut 10 and the No. 1 nut 8, so that the relative height difference between the circular wheel cutter 2 and the auxiliary wheel 12 can be adjusted, which is suitable for cutting different depths. The auxiliary wheels 12 on both sides of the circular wheel cutter 2 play a supporting role. When using this device for cutting, the device is placed on the material to be cut, the handle 11 is held, and pushed forward, so that the circular wheel cutter 2 and the auxiliary wheel 12 roll forward, the circular wheel cutter 2 cuts the material, and the auxiliary wheel 12 makes the entire device more stable during operation.

[0023] The device has a simple structure, low manufacturing cost and a wide range of applications. The relative height difference between the circular wheel cutter 2 and the auxiliary wheel 12 can be adjusted by setting a screw 9 to adjust the position of the connecting shaft 3 on the long hole 7, which is suitable for cutting at different depths. The auxiliary wheels 12 on both sides of the circular wheel cutter 2 play a supporting role, making the entire device more stable during operation and the cutting route easier to control than an ordinary knife.

[0024] It is known from common technical knowledge that the present invention can be implemented by other embodiments that do not deviate from its spirit or essential features. Therefore, the embodiments disclosed above are only illustrative in all respects and are not exclusive. All changes within the scope of the present invention or within the scope equivalent to the present invention are included in the present invention.
