[0017] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below with reference to the accompanying drawings.

[0018] like Figure 1 and Figure 2 As shown, an electric disc cutting device provided by an embodiment of the present application comprises a housing 1, a rotating shaft arranged on the housing 1, a motor arranged in the housing 1 and connected coaxially with one end of the rotating shaft, a large blade 2 arranged at the other end of the rotating shaft, a shield 3 arranged on the housing 1, and a bracket 4 arranged on the housing 1, wherein a working opening 100 is formed between the shield 3 and the bracket 4. A torsion spring 5 and an adjustable fastener 6 are also included, wherein the shield 3 is hinged to the housing 1 at one end away from the working opening 100, and the two ends of the torsion spring 5 are respectively against the housing 1 and the shield 3, so that the shield 3 rotates relative to the bracket 4 to increase the angle of the working opening 100, and the adjustable fastener 6 is used to fix the housing 1 and the shield 3.

[0019] In actual use, when it is necessary to adjust the angle of the working opening 100, the adjustable fastener 6 is loosened to allow the shield 3 to rotate under the action of the torsion spring 5, and then the adjustable fastener 6 is used to lock the shield 3 and the casing 1, so as to perform the cutting operation.

[0020] In the above design, the angle of the operating opening 100 can be adjusted in time, overcoming the operating limitations caused by safety regulations, so that products of different thicknesses can be cut.

[0021] Specifically: Figure 2 As shown, the housing 1 includes a first housing 11 and a second housing 12 symmetrically arranged, a first column 13 arranged outside the first housing 11, and a plurality of connecting bolts connecting the first housing 11 and the second housing 12. Figure 4 As shown, the guard 3 includes a side plate 31 hinged to the No. 1 column 13 and parallel to the end face of the large blade 2, and a retaining edge 32 arranged on the side plate 31 to shield the cutting edge of the large blade 2. The torsion spring 5 is sleeved on the No. 1 column 13, one end of the torsion spring 5 is against the retaining edge 32, and the other end of the torsion spring 5 is against the No. 1 shell 11.

[0022] In actual use, through the limitation of the other end of the torsion spring 5 and the first shell 11 , one end of the torsion spring 5 applies a force to the retaining edge 32 to enlarge the working opening 100 .

[0023] In the above design, the structural design and assembly method of the housing 1 , the shield 3 and the torsion spring 5 make the shield 3 more stable when rotated by the torsion spring 5 .

[0024] Specifically: Figure 2 and Figure 3 As shown, the No. 1 shell 11 is provided with a No. 1 hole, and the torsion spring 5 includes a spiral section 51 sleeved on the No. 1 column 13, a No. 1 bending section 52 connected to one end of the spiral end, and a No. 2 bending section 53 connected to the other end of the spiral section 51, the end of the No. 1 bending section 52 extends into the No. 1 hole, and the No. 2 bending section 53 abuts against the retaining edge 32.

[0025] In actual use, the spiral section 51 is sleeved on the No. 1 column 13 , and the elastic force on the shield 3 changes through the elastic deformation of the No. 1 bending end and the No. 2 bending section 53 .

[0026] In the above design, the structural design and assembly method of the torsion spring 5 can make the installation of the torsion spring 5 more stable and the elastic force on the shield 3 more stable.

[0027] Specifically: Figure 4As shown, an arc-shaped hole 310 is provided on the side plate 31, a No. 1 screw hole is provided on the No. 1 shell 11, and the adjustable fastener 6 is a No. 2 bolt. The No. 2 bolt includes a threaded section passing through the arc-shaped hole 310 and threadedly connected to the No. 1 screw hole, and an end head provided at the end of the threaded section, and the end head can be abutted against the side plate 31.

[0028] In actual use, when the working opening 100 needs to be adjusted, the No. 2 bolt is loosened, and then the shield 3 is rotated. When the shield 3 is rotated to a preset position, the No. 2 bolt is screwed again so that the No. 2 bolt locks the shield 3 and the casing 1.

[0029] In the above design, the shield 3 can be quickly loosened or locked, which effectively improves the efficiency of adjusting the shield 3.

[0030] Specifically: Figure 1 and Figure 2 As shown, the cutting edge of the straight blade 7 is offset toward the large blade 2 and contacts the cutting edge of the large blade 2 .

[0031] In actual use, when the large blade 2 rotates, the straight blade 7 abuts against the cutting edge of the large blade 2 to grind the cutting edge of the large blade 2.

[0032] In the above design, it is possible to ensure that the cutting edge of the large blade 2 is polished, thereby increasing the service life of the large blade 2.

[0033] To further explain in detail, it should be understood that the above is only a specific embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
