DETAILED DESCRIPTION OF THE EMBODIMENTS

[0019] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model. Embodiment 1

[0020] Please refer to Figures 1 - 5, the present utility model discloses an anti - detachment structure for grinding wheel installation, including a mounting seat 1 fixedly installed at the output end of a motor and a grinding wheel body 2. The front end face of the mounting seat 1 is fixedly installed with a mounting shaft 11. The outer wall of the mounting shaft 11 is detachably installed with a mounting cylinder 12. The outer wall of the mounting shaft 11 is symmetrically provided with inwardly recessed mounting grooves 111. A fixing component 3 is arranged in the mounting grooves 111. The outer wall of the mounting cylinder 12 is provided with through grooves 121 corresponding to the mounting grooves 111. A limiting component 4 that cooperates with the fixing component 3 is arranged in the through grooves 121. A fixing ring 123 is installed on the outer wall of the mounting cylinder 12. The grinding wheel body 2 is detachably installed on the outer wall of the mounting cylinder 12 and is located between the fixing ring 123 and the limiting component 4.

[0021] Through the above design, by setting the mounting cylinder 12, the fixing ring 123, the fixing component 3 and the limiting component 4, it can prevent the grinding wheel from falling off during operation. When disassembling, the mounting cylinder 12 together with the grinding wheel body 2 can be removed, so that the grinding wheel body 2 can be quickly disassembled. During replacement and installation, it can be more rapid, thus improving the installation and disassembly efficiency.

[0022] Please refer to Figure 1 , Figure 2 , Figure 3 , Figure 5 , the fixing component 3 includes a spring 31 and a fixing tooth 32. The fixing tooth 32 is slidably connected in the mounting groove 111 and extends into the through groove 121. The spring 31 is arranged in the mounting groove 111, and both ends of the spring 31 are fixedly connected to the mounting groove 111 and the fixing tooth 32 respectively. By setting the spring 31 and the fixing tooth 32, the spring 31 can be used to push the fixing tooth 32 into the through groove 121 to fix the mounting cylinder 12. When disassembling, it only needs to be pressed down to complete unlocking, making disassembly and installation more convenient. The limiting component 4 includes a limiting tooth 41 and a slider 42. The limiting tooth 41 is arranged in the through groove 121. A sliding groove 122 is arranged in the through groove 121. The slider 42 is arranged on the outer wall of the limiting tooth 41 and is slidably connected to the sliding groove 122. The inner ring of the grinding wheel body 2 is provided with a limiting groove 21 that cooperates with the limiting tooth 41. By setting the limiting tooth 41, the slider 42 and the sliding groove 122, the limiting tooth 41 can be pushed upward out of the through groove 121 by the fixing tooth 32 to cooperate with the fixing ring 123 to realize the limitation of the grinding wheel, and the slider 42 and the sliding groove 122 can facilitate the sliding of the limiting tooth 41. Embodiment Two

[0023] Based on the above Embodiment One, please refer to Figure 2, a rounded corner is provided on the front end face of the fixed tooth 32. By providing the rounded corner, when contacting the mounting cylinder 12, the mounting cylinder 12 can press the fixed tooth 32 into the mounting groove 111 through the guidance of the arc surface, thereby facilitating the loading of the mounting cylinder 12 and improving the convenience of installation. Arc surfaces are symmetrically provided on the left and right of the upper end face of the fixed tooth 32. By providing the arc surfaces, when the spring 31 pushes the fixed tooth 32 into the through groove 121, the fixed tooth 32 can be conveniently engaged through the guidance of the arc surfaces. A bevel surface is provided on the front end face of the limiting tooth 41. By providing the bevel surface, when loading the grinding wheel, the limiting tooth 41 can be pushed back into the through groove 121 by the grinding wheel through the guidance of the bevel surface, thereby facilitating the loading of the grinding wheel.

[0024] Working principle and usage process of the present utility model:

[0025] During installation, the grinding wheel body 2 is loaded onto the outer wall of the mounting cylinder 12. When the grinding wheel body 2 contacts the bevel surface, the limiting tooth 41 is pushed into the through hole. As the grinding wheel body 2 is loaded, when the grinding wheel body 2 contacts the mounting ring, the installation is completed. The mounting cylinder 12 is sleeved on the mounting shaft 11. When the mounting cylinder 12 contacts the rounded corner of the fixed tooth 32, through the guidance of the rounded corner, the mounting cylinder 12 pushes the fixed tooth 32 into the mounting groove 111, and the fixed tooth 32 compresses the spring 31. As the mounting cylinder 12 is loaded, when the fixed tooth 32 contacts the through groove 121, it is pushed by the spring 31 to engage into the through groove 121 and push out the limiting tooth 41. At this time, the installation is completed. During disassembly, just press the limiting tooth 41, so that the limiting tooth 41 pushes the mounting tooth and pushes the mounting tooth out of the through groove 121 to achieve unlocking. At this time, the mounting tooth compresses the spring 31, and then directly pull out the mounting cylinder 12, so that the mounting cylinder 12 and the grinding wheel body 2 are separated from the mounting shaft 11 together, and the disassembly can be completed.
