[0035] The locking mechanism 3 includes a cylindrical locking groove 301, a slot 302, a threaded column 306 and a locking cylinder 303. The cylindrical locking groove 301 is provided inside the cylindrical grinding wheel body 1, and the cylindrical locking groove 301 is arranged along the axial direction of the cylindrical grinding wheel body 1. One end of the cylindrical locking groove 301 passes through one end of the cylindrical grinding wheel body 1. The slot 302 is provided on the side of the cylindrical grinding wheel body 1, and the slot 302 passes through the cylindrical locking groove 301. The locking groove 301 is provided, and the threaded column 306 is fixedly installed inside the other end of the cylindrical locking groove 301. The cross section of the locking cylinder 303 is elliptical, and a fixing block 304 is fixedly installed at one end of the locking cylinder 303. A threaded hole 305 is opened inside the fixing block 304. One end of the threaded column 306 is screwed into the threaded hole 305. The locking cylinder 303 is fixed in the cylindrical locking groove 301 through the threaded column 306 and the threaded hole 305.

[0036] Among them, both ends of the grinding belt 2 are free ends, and the grinding belt 2 is covered on the side of the cylindrical grinding wheel body 1. Both ends of the grinding belt 2 pass through the slot 302 and are inserted into the interior of the cylindrical locking groove 301, and both ends of the grinding belt 2 are pressed against the inner wall of the cylindrical locking groove 301 by the outer wall of the locking cylinder 303.

[0037] The grinding wheel that adopts the above technical solution is easy to replace the abrasive material. The grinding belt 2 is installed on the cylindrical grinding wheel body 1 through the locking mechanism 3. The locking mechanism 3 is mainly composed of a cylindrical locking groove 301, a slot 302, a threaded column 306 and a locking cylinder 303. The locking cylinder 303 is fixed in the cylindrical locking groove 301 through the threaded column 306 and the threaded hole 305. At the same time, the outer wall of the locking cylinder 303 is pressed against the inner wall of the cylindrical locking groove 301 at both ends of the grinding belt 2. It only needs to rotate the locking cylinder 303 to achieve the purpose of locking or unlocking the grinding belt 2. The operation is relatively convenient, which makes it convenient to disassemble and replace the grinding belt 2, and can effectively improve work efficiency.

[0038] In order to facilitate the installation of the grinding wheel with easy replacement of abrasive materials on the grinder, a connecting seat 5 is fixedly installed on one end of the cylindrical grinding wheel body 1 by screws, and a connecting shaft 6 is installed on the connecting seat 5 by screws. The connecting shaft 6 is used to connect the output shaft of the grinder. In order to ensure that the grinding wheel with easy replacement of abrasive materials can run stably, the connecting shaft 6 is coaxially arranged with the cylindrical grinding wheel body 1.

[0039] In order to avoid a potential safety hazard caused by one end of the locking cylinder 303 being exposed from the cylindrical locking groove 301 , the length of the locking cylinder 303 is set to be no greater than the depth of the cylindrical locking groove 301 .

[0040] In order to facilitate the rotation of the locking cylinder 303, a tool 4 for operating the locking cylinder 303 is also provided. The tool 4 includes an insertion rod 401 and an operating rod 402. The cross-section of the insertion rod 401 is elliptical, and one end of the insertion rod 401 is inserted into one end of the locking cylinder 303 and will not rotate. The operating rod 402 is fixedly installed on the other end of the insertion rod 401, and the operating rod 402 is arranged perpendicular to the insertion rod 401. When in use, hold the operating rod 402 and insert one end of the insertion rod 401 into one end of the locking cylinder 303, and the locking cylinder 303 can be rotated using the operating rod 402.

[0041] Specifically, in this embodiment, in order to prevent the two ends of the operating rod 402 from accidentally scratching the user's hands, the edges of both ends of the operating rod 402 are set to have rounded corners.

[0042] In summary, the grinding wheel provided in this embodiment, which is convenient for replacing abrasive materials, has the following advantages:

[0043] The grinding wheel, which is convenient for replacing abrasive materials, has both ends of the grinding belt 2 pressed against the inner wall of the cylindrical locking groove 301 by the outer wall of the locking cylinder 303. The grinding belt 2 can be locked or unlocked by simply rotating the locking cylinder 303. The operation is convenient, making it easy to disassemble and replace the grinding belt 2, which can effectively improve work efficiency.

[0044] When in use, hold the operating rod 402 to insert one end of the insertion rod 401 into one end of the locking cylinder 303, and rotate the locking cylinder 303 to lock or unlock the grinding belt 2. When the grinding belt 2 needs to be removed, rotate the locking cylinder 303 to loosen the grinding belt 2. When the grinding belt 2 needs to be installed on the cylindrical grinding wheel body 1, wrap the grinding belt 2 on the side of the cylindrical grinding wheel body 1, and insert both ends of the grinding belt 2 through the slot 302 into the cylindrical locking groove 301. Then rotate the locking cylinder 303 to tighten the two ends of the grinding belt 2 against the inner wall of the cylindrical locking groove 301.

[0045] The above are only preferred embodiments of the present invention, and do not limit the implementation mode and protection scope of the present invention. Those skilled in the art should be aware that all solutions obtained by equivalent substitutions and obvious changes made using the description and illustrations of the present invention should be included in the protection scope of the present invention.
