[0036] As Figs. 1 to 3As shown in the figure, the embodiment provides an angle grinder cutting auxiliary tool for assisting the angle grinder 100 to cut the metal plate 300 placed on the workbench surface 200. The angle grinder cutting auxiliary tool comprises a guide rail 1, a connecting frame 2, a rocker arm 3 and a mounting piece 4. The guide rail 1 is press-connected to the metal plate 300 and fixedly connected with the workbench surface 200. Specifically, the guide rail 1 is laid on the metal plate 300 and the area exposed from the metal plate 300 is fixedly connected with the workbench surface 200 by bolts. The guide rail 1 is laid along the linear cutting path of the metal plate 300. The connecting frame 2 is slidingly arranged on the guide rail 1 and can move along the direction in which the guide rail 1 is laid. One end of the rocker arm 3 is rotationally connected with the connecting frame 2. The mounting piece 4 is rotationally arranged at the other end of the rocker arm 3 and away from the guide rail 1. The angle grinder 100 is connected with the mounting piece 4. The mounting piece 4 is away from the guide rail 1, which facilitates the mutual assembly between the angle grinder 100 and the mounting piece 4. By laying the guide rail 1 along the linear cutting path of the metal plate 300, when the connecting frame 2 is pushed to move along the guide rail 1, the angle grinder 100 is driven to move along the linear cutting path required by the metal plate 300, thereby avoiding the problem of the cutting path of the metal plate 300 being skewed and avoiding the metal plate 300 being scrapped due to the cutting problem. The rocker arm 3 is rotationally connected with the connecting frame 2. By controlling the rotation angle of the rocker arm 3 relative to the connecting frame 2, the cutting depth of the angle grinder 100 on the metal plate 300 can be controlled, thereby improving the flexibility of the angle grinder cutting auxiliary tool. The mounting piece 4 is rotationally connected with the rocker arm 3. The worker can make the angle grinder 100 abut against the metal plate 300 at different angles according to the cutting conditions, thereby realizing more stable cutting of the metal plate 300.

[0037] In the embodiment, the guide rail 1 is fixedly connected with the workbench surface 200 by bolts, i.e., the guide rail 1 and the workbench surface 200 can be detached. Thus, the laying direction of the guide rail 1 can be adjusted according to the linear cutting path of the metal plate 300, thereby further improving the flexibility of the angle grinder cutting auxiliary tool.

[0038] Further, a plurality of screw holes 11 are arranged on the guide rail 1 at intervals. The angle grinder cutting auxiliary tool further comprises a plurality of locking pieces corresponding to the plurality of screw holes 11. After the locking pieces are threadedly connected with the screw holes 11, the locking pieces abut against the metal plate 300. Thus, the locking pieces can clamp the metal plate 300 on the workbench surface 200. The plurality of locking pieces can clamp the metal plate 300 and the workbench surface 200 at multiple points, thereby avoiding the metal plate 300 being deviated during the cutting process by the angle grinder 100, which affects the cutting path of the metal plate 300. In the embodiment, the locking pieces can be selected as bolts.

[0039] In this embodiment, the angle grinder cutting auxiliary tool further comprises an elastic member 5 connected to the rocker arm 3 and the connecting frame 2. The elastic member 5 is arranged to facilitate the staff to control the rocker arm 3 more labor-saving, thereby achieving more accurate control of the cutting depth of the angle grinder 100 on the metal plate 300. After the staff releases the rocker arm 3, the rocker arm 3 can be automatically reset under the action of the elastic member 5. Specifically, the elastic member 5 can be a spring.

[0040] Exemplarily, the connecting frame 2 comprises a sliding block 21 and a fixed support 22, wherein the sliding block 21 is movably connected to the guide rail 1, and the fixed support 22 is fixedly connected to the sliding block 21. When the fixed support 22 is subjected to an external force, the sliding block 21 will move along the guide rail 1, thereby moving the angle grinder 100. The arrangement of the sliding block 21 enables the connecting frame 2 to move along the guide rail 1 more smoothly. Further, the fixed support 22 comprises a first lifting lug 221, a second lifting lug 222, and a pin shaft 223. The rocker arm 3 is arranged between the first lifting lug 221 and the second lifting lug 222, and the pin shaft 223 penetrates the first lifting lug 221, the rocker arm 3, and the second lifting lug 222, thereby achieving the rotational connection of the rocker arm 3 and the fixed support 22, and enabling the layout of the rocker arm 3 and the fixed support 22 to be more reasonable, further improving the rationality of the design of the angle grinder cutting auxiliary tool.

[0041] As a preferred, the elastic member 5 is provided with two hook portions 51 at its two ends, and a first mounting portion 31 is arranged on the rocker arm 3. The two hook portions 51 are respectively hooked on the first mounting portion 31 and the pin shaft 223. The arrangement of the hook portions 51 enables the staff to quickly assemble the elastic member 5, and enables the elastic member 5 to be more stably arranged between the rocker arm 3 and the fixed support 22. Specifically, the elastic member 5 is hooked on the pin shaft 223 of the second lifting lug 222 and the side wall region of the fixed support 22, thereby further improving the rationality of the layout of the elastic member 5 and the fixed support 22, and making the design of the angle grinder cutting auxiliary tool more reasonable.

[0042] Exemplarily, the mounting member 4 comprises a mounting seat 41, a connecting shaft 42, and a bearing. A mounting hole is arranged on the rocker arm 3, and the bearing is arranged in the mounting hole. The connecting shaft 42 penetrates the inner ring of the bearing and is connected to the mounting seat 41. In this way, the mounting seat 41 can rotate relative to the rocker arm 3. The angle grinder 100 is connected to the mounting seat 41, thereby enabling the angle grinder 100 to rotate relative to the rocker arm 3, and achieving that the angle grinder 100 can cut the metal plate 300 at different angles. Further, the mounting member 4 further comprises a retaining ring 43, which is clamped on the outer periphery of the connecting shaft 42 and abuts against the end face of the inner ring of the bearing. The arrangement of the retaining ring 43 can prevent the bearing from moving during rotation, thereby further improving the stability and smoothness of the rotation of the bearing.

[0043] Further, the mounting seat 41 is provided with an assembly groove 411, and the main body of the angle grinder 100 is fixed in the assembly groove 411 by bolts. Specifically, an installation groove can be arranged on the main body of the angle grinder 100, and an internal thread is arranged in the installation groove. The external thread of the bolt is screwed with the internal thread, so that the angle grinder 100 and the assembly groove 411 are assembled with each other. Preferably, the cross-sectional shape of the assembly groove 411 is U-shaped, so that the main body of the angle grinder 100 is wrapped in the circumferential direction in a larger range, and the connection between the angle grinder 100 and the assembly groove 411 is more stable.

[0044] In the embodiment, the angle grinder cutting auxiliary tool further comprises a gasket, which is arranged in the gap between the guide rail 1 and the workbench surface 200. The gasket is arranged to make the guide rail 1 more stably connected with the workbench surface 200. The thickness of the gasket can be adjusted according to the thickness of the metal plate 300, so as to further improve the stability of the guide rail 1.
