[0143] like Figure 9 As shown, the support component 500 includes a first support member 510 and a second connecting member 520. The first support member 510 is provided on the mounting frame component 100 for supporting the mounting frame component 100; the second connecting member 520 is provided at the connection between the mounting frame component 100 and the first support member 510 for rotatably connecting the first support member 510 to the mounting frame component 100.

[0144] Specifically, the first support member 510 is arranged in a plate-shaped structure, and the first support member 510 is rotatably connected to the mounting frame member 110 through the second connecting member 520; when the overall device has no working requirements, the first support member 510 can be folded on the mounting frame member 110, thereby improving the convenience of the overall device; when the overall device is in operation, the first support member 510 and the mounting frame member 110 are at a right angle, so that the first support member 510 can support the overall structure.

[0145] In some embodiments, the first support member 510 includes but is not limited to a metal plate.

[0146] Specifically, the second connecting member 520 is connected to the first supporting member 510 and the mounting frame member 110 respectively by welding, riveting or bolting. The second connecting member 520 can enable the first supporting member 510 and the cutting member 220 to be rotatably connected.

[0147] In some embodiments, the second connecting member 520 includes but is not limited to a hinge.

[0148] More specifically, the number of the second connecting members 520 is two, and the two second connecting members 520 are spaced apart along the length direction of the first supporting member 510 .

[0149] In some embodiments, the number of the second connecting members 520 may be 1, 3, etc., that is, the number of the second connecting members 520 may be set according to actual connection requirements, and no excessive restrictions are imposed herein.

[0150] The method of using this embodiment is as follows:

[0151] In actual work, before the operator performs cutting operations, the operator can rotate the first support member 510 so that the first support member 510 is arranged at a right angle to the mounting bracket 110. The operator can place the first support member 510 on the ground or a workbench to support the entire device.

[0152] The advantage of this embodiment is that by arranging the support component on the mounting frame component, the support component and the mounting frame component are arranged at right angles, and the support component can be abutted against the ground, thereby supporting the entire device and improving the convenience of operation.

[0156] Specifically, the second support member 530 is arranged in a plate-shaped structure, and the second support member 530 is rotatably connected to the mounting frame member 110 through the third connecting member 540, and is symmetrically arranged with the first support member 510; when the overall device has no working requirements, the second support member 530 can be folded on the mounting frame member 110, thereby improving the convenience of the overall device; when the overall device is in operation, the first support member 510, the second support member 530 and the mounting frame member 110 are at right angles, so that the first support member 510 and the second support member 530 can support the overall structure.

[0157] In some embodiments, the second support member 530 includes but is not limited to a metal plate.

[0158] Specifically, the third connecting member 540 is connected to the second supporting member 530 and the mounting frame member 110 respectively by welding, riveting or bolting, and the third connecting member 540 can enable the second supporting member 530 and the cutting member 220 to be rotatably connected.

[0159] In some embodiments, the third connecting member 540 includes but is not limited to a hinge.

[0160] More specifically, the number of the third connecting members 540 is two, and the two third connecting members 540 are spaced apart along the length direction of the second supporting member 530 .

[0161] In some embodiments, the number of the third connecting members 540 may be 1, 3, etc., that is, the number of the third connecting members 540 may be set according to actual connection requirements, and no excessive restrictions are imposed herein.

[0162] The method of using this embodiment is as follows:

[0163] In actual work, before the operator performs the cutting operation, the operator can rotate the first support member 510 and the second support member 530 so that the first support member 510 and the second support member 530 are arranged at right angles to the mounting frame 110. The operator can place the first support member 510 and the second support member 530 on the ground or on a workbench to support the entire device.

[0164] The advantage of this embodiment is that by arranging the support component on the mounting frame component, the support component and the mounting frame component are arranged at right angles, and the support component can be abutted against the ground, thereby supporting the entire device and improving the convenience of operation.
