[0026] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.
[0027] In order to protect the grinding disc when it is not practical, as an embodiment of the present invention, Figure 1-Figure 4 As shown, the rear cover shell of an angle grinder described in the present invention includes a rear cover 1, a mounting column 11 is provided at the center of the rear cover 1, the mounting column 11 is used for the base plate 3 to be installed in a sleeve manner, a mounting groove 8 is opened at the center of the base plate 3, the mounting groove 8 is used for the mounting column 11 to pass through, and a guard plate 2 is fixedly connected to the top end of the base plate 3, and the guard plate 2 is arranged in an arc-shaped structure.
[0028] During use, the base plate 3 is installed with the mounting groove 8 placed on the mounting column 11, so that the base plate 3 can be rotated on the rear shell cover 1. When the base plate 3 is fully rotated out, the guard plate 2 can protect the exposed edge of the grinding disc to prevent the edge of the grinding disc from being damaged by collision.
[0029] For example, Figure 1-4 As shown, the present invention further includes that the top end of the installation column 11 is fixedly connected with a threaded column 12, and the threaded column 12 is used for threaded installation of the limiting piece 9.
[0030] When in use, the limiting piece 9 is installed on the threaded column 12 through the thread, so that the limiting piece 9 can limit the position of the bottom plate 3;
[0031] It should be noted that the limiting piece 9 does not interfere with the rotation of the bottom plate 3 and only limits the position of the bottom plate 3 .
[0032] For example, Figure 1-4 As shown, the present invention further includes that a slide groove 5 is provided inside the rear shell cover 1 , and the slide groove 5 is used for sliding installation of the rotating rod 7 .
[0033] During use, during the installation process of the base plate 3, the push block 6 needs to be passed through the slide groove 5, so that the rotating rod 7 is located in the slide groove 5, so that the push block 6 is at the bottom of the rear shell cover 1, making it convenient for the staff to rotate the base plate 3 along the slide groove 5.
[0034] For example, Figure 1-4As shown, the present invention further includes that the top end of the rotating rod 7 is fixedly connected to the bottom of the base plate 3 , and the bottom end of the rotating rod 7 is movably connected to the top end of the push block 6 .
[0035] When the angle grinder is not in use, the push block 6 can be pushed to allow the rotating rod 7 to drive the bottom plate 3 to rotate completely out of the rear housing cover 1.
[0036] For example, Figure 1-4 As shown, the present invention further includes that a magnetic block 4 is fixedly connected to one side of the bottom plate 3 , and the magnetic block 4 is magnetically connected to both ends of the rear shell cover 1 .
[0037] During use, when the bottom plate 3 is completely rotated into the rear shell cover 1, the magnetic block 4 can be sucked at one end of the rear shell cover 1 to fix the bottom plate 3. When the bottom plate 3 is completely rotated out from the rear shell cover 1, the magnetic block 4 can be sucked at the other end of the rear shell cover 1 to fix the bottom plate 3.
[0038] For example, Figure 1-4 As shown, the present invention further includes that the rear shell cover 1 is sleeved on the outside of the angle grinder rotor 10 , and the top end of the angle grinder rotor 10 passes through the mounting column 11 and the threaded column 12 .
[0039] When in use, the angle grinder rotor 10 is used for sleeve installation of the grinding disc of the angle grinder and drives the grinding disc to rotate.
[0040] When the angle grinder is not in use, the push block 6 can be pushed to allow the rotating rod 7 to drive the bottom plate 3 to rotate completely out of the rear shell cover 1, and the magnetic block 4 can be attracted to one end of the rear shell cover 1, so that the guard plate 2 can protect the exposed edge of the grinding disc to prevent the edge of the grinding disc from being damaged by collision.
[0041] When installing the base plate 3, first put the mounting groove 8 on the mounting column 11, and then install the limit plate 9 on the threaded column 12 through threads, so that the limit plate 9 can limit the position of the base plate 3. During the installation process, the push block 6 needs to pass through the slide groove 5, and let the rotating rod 7 be located in the slide groove 5, so that the push block 6 is at the bottom of the rear shell cover 1, which is convenient for the staff to rotate the base plate 3 along the slide groove 5. When the base plate 3 is completely rotated into the rear shell cover 1, the magnetic block 4 can be sucked at one end of the rear shell cover 1 to fix the base plate 3. When the base plate 3 is completely rotated out from the rear shell cover 1, the magnetic block 4 can be sucked at the other end of the rear shell cover 1 to fix the base plate 3.
