[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Example: Figures 1-4 As shown, this utility model provides a brazing abrasive tool with diamond lines arranged at intervals, including an abrasive body 1. A conical column 2 is fixedly connected to the top of the abrasive body 1, and a top seat 3 is fixedly connected to the top of the conical column 2. The upper and lower surfaces of the top seat 3 are both set as inclined surfaces. A connecting seat 4 is provided at the top of the abrasive body 1. An installation groove 5 is opened inside the connecting seat 4. The conical column 2 and the top seat 3 are movably inserted into the installation groove 5. A sliding groove 6 is opened inside the abrasive body 1 on both sides of the installation groove 5. A locking block 7 is slidably engaged inside the sliding groove 6 and engages with the top seat 3. By inserting the conical column 2 and the top seat 3 into the installation groove 5 and engaging the top seat 3 with the locking block 7, the vertical movement of the conical column 2 is limited.

[0020] A guide rod 8 is fixedly connected to the side of the snap-fit ​​block 7 away from the top seat 3. A spring 10 is provided between the side of the snap-fit ​​block 7 near the guide rod 8 and the inner wall of the slide groove 6. The spring 10 is movably sleeved on the outside of the guide rod 8.

[0021] By adopting the above technical solution, when installing the mold body 1, the spring 10 is set to facilitate the reset of the snap-fit ​​block 7. At the same time, the elastic force of the spring 10 makes the snap-fit ​​block 7 and the top seat 3 more securely snap-fitted together.

[0022] The end of the guide rod 8 away from the snap-fit ​​block 7 extends movably to the outside of the connecting seat 4 and is fixedly connected to the limit block 9.

[0023] By adopting the above technical solution and setting the limiting block 9, it is convenient to limit the lateral movement of the locking block 7, and prevent the locking block 7 from sliding out of the inside of the slide groove 6 when the conical column 2 is pulled out.

[0024] The bottom end of the connecting seat 4 is fixedly connected with a ring-shaped magnetic plate one 11, and the top end of the abrasive tool body 1 is fixedly connected with a ring-shaped magnetic plate two 12, and the ring-shaped magnetic plate one 11 and the ring-shaped magnetic plate two 12 attract each other.

[0025] By adopting the above technical scheme, the abrasive tool body 1 is installed more firmly through the mutual attraction between the ring-shaped magnetic plate one 11 and the ring-shaped magnetic plate two 12.

[0026] Two symmetrically distributed positioning grooves 14 are arranged at the top end of the inner wall of the mounting groove 5, and the top end of the top seat 3 is fixedly connected with two symmetrically distributed positioning rods 13, and the top end of the positioning rod 13 is movably inserted into the positioning groove 14.

[0027] By adopting the above technical scheme, the abrasive tool body 1 is positioned through the cooperation between the positioning rod 13 and the positioning groove 14, so as to prevent the relative rotation between the abrasive tool body 1 and the connecting seat 4.

[0028] The outer surface of the abrasive tool body 1 is brazed with diamond abrasives 15 arranged in line intervals.

[0029] By adopting the above technical scheme, the diamond abrasives 15 arranged in line intervals are brazed on the outer surface of the abrasive tool body 1, which significantly improves the wear resistance of the abrasive tool, thereby prolonging the service life thereof.

[0030] Working principle: when the brazed abrasive tool is used, the diamond abrasives 15 arranged in line intervals are brazed on the outer surface of the abrasive tool body 1, which significantly improves the wear resistance of the abrasive tool, thereby prolonging the service life thereof;

[0031] When the abrasive tool is installed with the connecting seat, the conical column 2 at the top end of the abrasive tool body 1 and the top seat 3 are inserted into the inside of the mounting groove 5, and the positioning rod 13 corresponds to the position of the positioning groove 14, when the top end of the top seat 3 is in contact with the clamping block 7, the two clamping blocks 7 are simultaneously pushed to move to one side of the spring 10, when the top seat 3 moves to the bottom end and corresponds to the position of the clamping block 7, the spring 10 is used to push the clamping block 7 to move to one side of the top seat 3, so that the clamping block 7 and the top seat 3 are clamped with each other, thereby limiting the pulling out of the abrasive tool body 1, at the same time, the ring-shaped magnetic plate one 11 and the ring-shaped magnetic plate two 12 attract each other, so that the abrasive tool body 1 is installed more firmly, at this time, the positioning rod 13 is inserted into the inside of the positioning groove 14, which limits the relative rotation between the abrasive tool body 1 and the connecting seat 4, and the installation of the abrasive tool body 1 is completed.

[0032] When the abrasive tool body 1 needs to be disassembled, by applying appropriate force to the abrasive tool body 1, the top seat 3 and the conical column 2 can be pulled out from the inside of the mounting groove 5 through the cooperation between the bottom end of the top seat 3 and the clamping block 7, thereby completing the disassembly of the abrasive tool body 1.

[0033] Obviously, those skilled in the art can make various modifications and variations to the present application without departing from the spirit and scope of the present application. Thus, if these modifications and variations of the present application fall within the scope of the claims of the present application and their equivalents, the present application also intends to include these modifications and variations.
